7 | _a (Unix.U): |
8 | This variable defines the extension used for ordinary libraries. |
9 | For unix, it is '.a'. The '.' is included. Other possible |
10 | values include '.lib'. |
11 | |
12 | _exe (Unix.U): |
13 | This variable defines the extension used for executable files. |
14 | For unix it is empty. Other possible values include '.exe'. |
15 | |
16 | _o (Unix.U): |
17 | This variable defines the extension used for object files. |
18 | For unix, it is '.o'. The '.' is included. Other possible |
19 | values include '.obj'. |
20 | |
21 | afs (afs.U): |
22 | This variable is set to 'true' if AFS (Andrew File System) is used |
23 | on the system, 'false' otherwise. It is possible to override this |
24 | with a hint value or command line option, but you'd better know |
25 | what you are doing. |
26 | |
27 | alignbytes (alignbytes.U): |
28 | This variable holds the number of bytes required to align a |
87b71857 |
29 | double-- or a long double when applicable. Usual values are |
30 | 2, 4 and 8. The default is eight, for safety. |
781b178c |
31 | |
32 | ansi2knr (ansi2knr.U): |
33 | This variable is set if the user needs to run ansi2knr. |
34 | Currently, this is not supported, so we just abort. |
35 | |
36 | aphostname (d_gethname.U): |
37 | This variable contains the command which can be used to compute the |
38 | host name. The command is fully qualified by its absolute path, to make |
39 | it safe when used by a process with super-user privileges. |
40 | |
ff935051 |
41 | api_revision (patchlevel.U): |
42 | The three variables, api_revision, api_version, and |
43 | api_subversion, specify the version of the oldest perl binary |
44 | compatible with the present perl. In a full version string |
45 | such as '5.6.1', api_revision is the '5'. |
46 | Prior to 5.5.640, the format was a floating point number, |
47 | like 5.00563. |
48 | perl.c:incpush() and lib/lib.pm will automatically search in |
49 | $sitelib/.. for older directories back to the limit specified |
50 | by these api_ variables. This is only useful if you have a |
51 | perl library directory tree structured like the default one. |
52 | See INSTALL for how this works. The versioned site_perl |
53 | directory was introduced in 5.005, so that is the lowest |
54 | possible value. The version list appropriate for the current |
55 | system is determined in inc_version_list.U. |
56 | XXX To do: Since compatibility can depend on compile time |
57 | options (such as bincompat, longlong, etc.) it should |
58 | (perhaps) be set by Configure, but currently it isn't. |
59 | Currently, we read a hard-wired value from patchlevel.h. |
60 | Perhaps what we ought to do is take the hard-wired value from |
61 | patchlevel.h but then modify it if the current Configure |
62 | options warrant. patchlevel.h then would use an #ifdef guard. |
63 | |
64 | api_subversion (patchlevel.U): |
65 | The three variables, api_revision, api_version, and |
66 | api_subversion, specify the version of the oldest perl binary |
67 | compatible with the present perl. In a full version string |
68 | such as '5.6.1', api_subversion is the '1'. See api_revision for |
69 | full details. |
70 | |
71 | api_version (patchlevel.U): |
72 | The three variables, api_revision, api_version, and |
73 | api_subversion, specify the version of the oldest perl binary |
74 | compatible with the present perl. In a full version string |
75 | such as '5.6.1', api_version is the '6'. See api_revision for |
76 | full details. As a special case, 5.5.0 is rendered in the |
77 | old-style as 5.005. (In the 5.005_0x maintenance series, |
78 | this was the only versioned directory in $sitelib.) |
79 | |
80 | api_versionstring (patchlevel.U): |
81 | This variable combines api_revision, api_version, and |
82 | api_subversion in a format such as 5.6.1 (or 5_6_1) suitable |
83 | for use as a directory name. This is filesystem dependent. |

107 | |
108 | archobjs (Unix.U): |
109 | This variable defines any additional objects that must be linked |
110 | in with the program on this architecture. On unix, it is usually |
111 | empty. It is typically used to include emulations of unix calls |
112 | or other facilities. For perl on OS/2, for example, this would |
113 | include os2/os2.obj. |

2169 | to the C program that it should include <sys/wait.h>. |
2170 | |
2171 | i_termio (i_termio.U): |
2172 | This variable conditionally defines the I_TERMIO symbol, which |
2173 | indicates to the C program that it should include <termio.h> rather |
2174 | than <sgtty.h>. |
2175 | |
2176 | i_termios (i_termio.U): |
2177 | This variable conditionally defines the I_TERMIOS symbol, which |
2178 | indicates to the C program that the POSIX <termios.h> file is |
2179 | to be included. |
2180 | |
2181 | i_time (i_time.U): |
2182 | This variable conditionally defines I_TIME, which indicates |

2188 | |
0545a864 |
2189 | i_ustat (i_ustat.U): |
2190 | This variable conditionally defines the I_USTAT symbol, and indicates |
2191 | whether a C program should include <ustat.h>. |
2192 | |
781b178c |
2193 | i_utime (i_utime.U): |
2194 | This variable conditionally defines the I_UTIME symbol, and indicates |

2200 | and friends. |
2201 | |
2202 | i_varargs (i_varhdr.U): |
2203 | This variable conditionally defines I_VARARGS, which indicates |
2204 | to the C program that it should include <varargs.h>. |
2205 | |
2206 | i_varhdr (i_varhdr.U): |
2207 | Contains the name of the header to be included to get va_dcl definition. |
2208 | Typically one of varargs.h or stdarg.h. |
2209 | |
2210 | i_vfork (i_vfork.U): |
2211 | This variable conditionally defines the I_VFORK symbol, and indicates |
2212 | whether a C program should include vfork.h. |
2213 | |
2214 | ignore_versioned_solibs (libs.U): |
2215 | This variable should be non-empty if non-versioned shared |
2216 | libraries (libfoo.so.x.y) are to be ignored (because they |
2217 | cannot be linked against). |
2218 | |
ff935051 |
2219 | inc_version_list (inc_version_list.U): |
2220 | This variable specifies the list of subdirectories in over |
2221 | which perl.c:incpush() and lib/lib.pm will automatically |
3a096bf3 |
2222 | search when adding directories to @INC. The elements in |
2223 | the list are separated by spaces. This is only useful |
ff935051 |
2224 | if you have a perl library directory tree structured like the |
2225 | default one. See INSTALL for how this works. The versioned |
2226 | site_perl directory was introduced in 5.005, so that is the |
2227 | lowest possible value. |
2228 | |
3a096bf3 |
2229 | inc_version_list_init (inc_version_list.U): |
2230 | This variable holds the same list as inc_version_list, but |
2231 | each item is enclosed in double quotes and separated by commas, |
2232 | suitable for use in the PERL_INC_VERSION_LIST initialization. |
2233 | |
781b178c |
2234 | incpath (usrinc.U): |
2235 | This variable must preceed the normal include path to get hte |
2236 | right one, as in "$incpath/usr/include" or "$incpath/usr/lib". |
2237 | Value can be "" or "/bsd43" on mips. |
2238 | |
2239 | inews (Loc.U): |
2240 | This variable is defined but not used by Configure. |
2241 | The value is a plain '' and is not useful. |
2242 | |
2243 | installarchlib (archlib.U): |
2244 | This variable is really the same as archlibexp but may differ on |
2245 | those systems using AFS. For extra portability, only this variable |
2246 | should be used in makefiles. |
2247 | |
2248 | installbin (bin.U): |
2249 | This variable is the same as binexp unless AFS is running in which case |
2250 | the user is explicitely prompted for it. This variable should always |
2251 | be used in your makefiles for maximum portability. |
2252 | |
2253 | installman1dir (man1dir.U): |
2254 | This variable is really the same as man1direxp, unless you are using |
2255 | AFS in which case it points to the read/write location whereas |
2256 | man1direxp only points to the read-only access location. For extra |
2257 | portability, you should only use this variable within your makefiles. |
2258 | |
2259 | installman3dir (man3dir.U): |
2260 | This variable is really the same as man3direxp, unless you are using |
2261 | AFS in which case it points to the read/write location whereas |
2262 | man3direxp only points to the read-only access location. For extra |
2263 | portability, you should only use this variable within your makefiles. |
2264 | |
2265 | installprefix (installprefix.U): |
2266 | This variable holds the name of the directory below which |
2267 | "make install" will install the package. For most users, this |
2268 | is the same as prefix. However, it is useful for |
2269 | installing the software into a different (usually temporary) |
2270 | location after which it can be bundled up and moved somehow |
2271 | to the final location specified by prefix. |
2272 | |
2273 | installprefixexp (installprefix.U): |
2274 | This variable holds the full absolute path of installprefix |
2275 | with all ~-expansion done. |
2276 | |
2277 | installprivlib (privlib.U): |
2278 | This variable is really the same as privlibexp but may differ on |
2279 | those systems using AFS. For extra portability, only this variable |
2280 | should be used in makefiles. |
2281 | |
2282 | installscript (scriptdir.U): |
2283 | This variable is usually the same as scriptdirexp, unless you are on |
2284 | a system running AFS, in which case they may differ slightly. You |
2285 | should always use this variable within your makefiles for portability. |
2286 | |
2287 | installsitearch (sitearch.U): |
2288 | This variable is really the same as sitearchexp but may differ on |
2289 | those systems using AFS. For extra portability, only this variable |
2290 | should be used in makefiles. |
2291 | |
0617aed7 |
2292 | installsitebin (sitebin.U): |
2293 | This variable is usually the same as sitebinexp, unless you are on |
2294 | a system running AFS, in which case they may differ slightly. You |
2295 | should always use this variable within your makefiles for portability. |
2296 | |
781b178c |
2297 | installsitelib (sitelib.U): |
2298 | This variable is really the same as sitelibexp but may differ on |
2299 | those systems using AFS. For extra portability, only this variable |
2300 | should be used in makefiles. |
2301 | |
2302 | installstyle (installstyle.U): |
2303 | This variable describes the "style" of the perl installation. |
2304 | This is intended to be useful for tools that need to |
2305 | manipulate entire perl distributions. Perl itself doesn't use |
2306 | this to find its libraries -- the library directories are |
2307 | stored directly in Config.pm. Currently, there are only two |
2308 | styles: "lib" and "lib/perl5". The default library locations |
2309 | (e.g. privlib, sitelib) are either $prefix/lib or |
2310 | $prefix/lib/perl5. The former is useful if $prefix is a |
2311 | directory dedicated to perl (e.g. /opt/perl), while the latter |
2312 | is useful if $prefix is shared by many packages, e.g. if |
2313 | $prefix=/usr/local. |
2314 | This may later be extended to include other information, so |
2315 | be careful with pattern-matching on the results. |
2316 | For compatibility with perl5.005 and earlier, the default |
2317 | setting is based on whether or not $prefix contains the string |
2318 | "perl". |
2319 | |
2320 | installusrbinperl (instubperl.U): |
2321 | This variable tells whether Perl should be installed also as |
2322 | /usr/bin/perl in addition to |
2323 | $installbin/perl |
2324 | |
65f19062 |
2325 | installvendorarch (vendorarch.U): |
2326 | This variable is really the same as vendorarchexp but may differ on |
2327 | those systems using AFS. For extra portability, only this variable |
2328 | should be used in makefiles. |
2329 | |
0617aed7 |
2330 | installvendorbin (vendorbin.U): |
2331 | This variable is really the same as vendorbinexp but may differ on |
2332 | those systems using AFS. For extra portability, only this variable |

2334 | |
a3635516 |
2335 | installvendorlib (vendorlib.U): |
2336 | This variable is really the same as vendorlibexp but may differ on |

2363 | This variable contains a flag which will tell the C compiler and loader |
2364 | to produce a program running with a large memory model. It is up to |
2365 | the Makefile to use this. |
2366 | |
2367 | ld (dlsrc.U): |
2368 | This variable indicates the program to be used to link |
2369 | libraries for dynamic loading. On some systems, it is 'ld'. |
2370 | On ELF systems, it should be $cc. Mostly, we'll try to respect |
2371 | the hint file setting. |
2372 | |
2373 | lddlflags (dlsrc.U): |
2374 | This variable contains any special flags that might need to be |
2375 | passed to $ld to create a shared library suitable for dynamic |
2376 | loading. It is up to the makefile to use it. For hpux, it |
2377 | should be '-b'. For sunos 4.1, it is empty. |
2378 | |
2379 | ldflags (ccflags.U): |
2380 | This variable contains any additional C loader flags desired by |
2381 | the user. It is up to the Makefile to use this. |
2382 | |

2384 | This variable holds the name of the shared library |
2385 | search path, often LD_LIBRARY_PATH. To get an empty |
2386 | string, the hints file must set this to 'none'. |
2387 | |
2388 | less (Loc.U): |
5bf26616 |
2389 | This variable is used internally by Configure to determine the |
781b178c |
2390 | full pathname (if any) of the less program. After Configure runs, |
2391 | the value is reset to a plain "less" and is not useful. |
2392 | |

2400 | The perl executable is obtained by linking perlmain.c with |
2401 | libperl, any static extensions (usually just DynaLoader), |
2402 | and any other libraries needed on this system. libperl |
2403 | is usually libperl.a, but can also be libperl.so.xxx if |
2404 | the user wishes to build a perl executable with a shared |
2405 | library. |
2406 | |
2407 | libpth (libpth.U): |
2408 | This variable holds the general path (space-separated) used to find |
2409 | libraries. It is intended to be used by other units. |
2410 | |
2411 | libs (libs.U): |
2412 | This variable holds the additional libraries we want to use. |
2413 | It is up to the Makefile to deal with it. |
2414 | |
fe749a9f |
2415 | libsdirs (libs.U): |
2416 | This variable holds the directory names aka dirnames of the libraries |
2417 | we found and accepted, duplicates are removed. |
2418 | |

5bf26616 |
2448 | This variable is used internally by Configure to determine the |
781b178c |
2449 | full pathname (if any) of the ln program. After Configure runs, |
2450 | the value is reset to a plain "ln" and is not useful. |
2451 | |
2452 | lns (lns.U): |
2453 | This variable holds the name of the command to make |
2454 | symbolic links (if they are supported). It can be used |
2455 | in the Makefile. It is either 'ln -s' or 'ln' |
2456 | |
2457 | locincpth (ccflags.U): |
2458 | This variable contains a list of additional directories to be |
2459 | searched by the compiler. The appropriate '-I' directives will |
2460 | be added to ccflags. This is intended to simplify setting |
2461 | local directories from the Configure command line. |
2462 | It's not much, but it parallels the loclibpth stuff in libpth.U. |
2463 | |
2464 | loclibpth (libpth.U): |
2465 | This variable holds the paths (space-separated) used to find local |
2466 | libraries. It is prepended to libpth, and is intended to be easily |

2468 | |
2469 | longdblsize (d_longdbl.U): |
2470 | This variable contains the value of the LONG_DOUBLESIZE symbol, which |
2471 | indicates to the C program how many bytes there are in a long double, |

2495 | |
2496 | lseeksize (lseektype.U): |
2497 | This variable defines lseektype to be something like off_t, long, |
2498 | or whatever type is used to declare lseek offset's type in the |

2500 | |
2501 | lseektype (lseektype.U): |
2502 | This variable defines lseektype to be something like off_t, long, |
2503 | or whatever type is used to declare lseek offset's type in the |

2523 | Possible values are: |
2524 | make_set_make='#' # If your make program handles this for you, |
2525 | make_set_make="MAKE=$make" # if it doesn't. |
2526 | I used a comment character so that we can distinguish a |
2527 | 'set' value (from a previous config.sh or Configure '-D' option) |
2528 | from an uncomputed value. |
2529 | |
2530 | mallocobj (mallocsrc.U): |
2531 | This variable contains the name of the malloc.o that this package |
2532 | generates, if that malloc.o is preferred over the system malloc. |

2541 | |
2542 | malloctype (mallocsrc.U): |
2543 | This variable contains the kind of ptr returned by malloc and realloc. |
2544 | |
2545 | man1dir (man1dir.U): |
2546 | This variable contains the name of the directory in which manual |
2547 | source pages are to be put. It is the responsibility of the |
2548 | Makefile.SH to get the value of this into the proper command. |

2594 | |
fe749a9f |
2595 | mmaptype (d_mmap.U): |
2596 | This symbol contains the type of pointer returned by mmap() |
2597 | (and simultaneously the type of the first argument). |
2598 | It can be 'void *' or 'caddr_t'. |

2602 | system. Possible component values are none, split, unsplit, small, |
2603 | medium, large, and huge. The component values are space separated. |
2604 | |
2605 | modetype (modetype.U): |
2606 | This variable defines modetype to be something like mode_t, |
2607 | int, unsigned short, or whatever type is used to declare file |
2608 | modes for system calls. |
2609 | |
2610 | more (Loc.U): |
5bf26616 |
2611 | This variable is used internally by Configure to determine the |
781b178c |
2612 | full pathname (if any) of the more program. After Configure runs, |
2613 | the value is reset to a plain "more" and is not useful. |
2614 | |
2615 | multiarch (multiarch.U): |
2616 | This variable conditionally defines the MULTIARCH symbol |
2617 | which signifies the presence of multiplatform files. |
2618 | This is normally set by hints files. |
2619 | |
2620 | mv (Loc.U): |
2621 | This variable is defined but not used by Configure. |
2622 | The value is a plain '' and is not useful. |
2623 | |
2624 | myarchname (archname.U): |
2625 | This variable holds the architecture name computed by Configure in |
2626 | a previous run. It is not intended to be perused by any user and |
2627 | should never be set in a hint file. |
2628 | |
2629 | mydomain (myhostname.U): |
2630 | This variable contains the eventual value of the MYDOMAIN symbol, |
2631 | which is the domain of the host the program is going to run on. |
2632 | The domain must be appended to myhostname to form a complete host name. |
2633 | The dot comes with mydomain, and need not be supplied by the program. |
2634 | |
2635 | myhostname (myhostname.U): |
2636 | This variable contains the eventual value of the MYHOSTNAME symbol, |
2637 | which is the name of the host the program is going to run on. |
2638 | The domain is not kept with hostname, but must be gotten from mydomain. |
2639 | The dot comes with mydomain, and need not be supplied by the program. |
2640 | |
2641 | myuname (Oldconfig.U): |
2642 | The output of 'uname -a' if available, otherwise the hostname. On Xenix, |
2643 | pseudo variables assignments in the output are stripped, thank you. The |
2644 | whole thing is then lower-cased. |
2645 | |
2646 | n (n.U): |
2647 | This variable contains the '-n' flag if that is what causes the echo |
2648 | command to suppress newline. Otherwise it is null. Correct usage is |
2649 | $echo $n "prompt for a question: $c". |
2650 | |
2651 | netdb_hlen_type (netdbtype.U): |
2652 | This variable holds the type used for the 2nd argument to |
2653 | gethostbyaddr(). Usually, this is int or size_t or unsigned. |

2655 | |
2656 | netdb_host_type (netdbtype.U): |
2657 | This variable holds the type used for the 1st argument to |
2658 | gethostbyaddr(). Usually, this is char * or void *, possibly |
2659 | with or without a const prefix. |

2661 | |
2662 | netdb_name_type (netdbtype.U): |
2663 | This variable holds the type used for the argument to |
2664 | gethostbyname(). Usually, this is char * or const char *. |
2665 | This is only useful if you have gethostbyname(), naturally. |
2666 | |
2667 | netdb_net_type (netdbtype.U): |
2668 | This variable holds the type used for the 1st argument to |
2669 | getnetbyaddr(). Usually, this is int or long. |
2670 | This is only useful if you have getnetbyaddr(), naturally. |
2671 | |
2672 | nm (Loc.U): |
5bf26616 |
2673 | This variable is used internally by Configure to determine the |
781b178c |
2674 | full pathname (if any) of the nm program. After Configure runs, |
2675 | the value is reset to a plain "nm" and is not useful. |
2676 | |
2677 | nm_opt (usenm.U): |
2678 | This variable holds the options that may be necessary for nm. |
2679 | |
2680 | nm_so_opt (usenm.U): |
2681 | This variable holds the options that may be necessary for nm |
2682 | to work on a shared library but that can not be used on an |
2683 | archive library. Currently, this is only used by Linux, where |
2684 | nm --dynamic is *required* to get symbols from an ELF library which |
2685 | has been stripped, but nm --dynamic is *fatal* on an archive library. |
2686 | Maybe Linux should just always set usenm=false. |
2687 | |
2688 | nonxs_ext (Extensions.U): |
2689 | This variable holds a list of all non-xs extensions included |
2690 | in the package. All of them will be built. |
2691 | |
2692 | nroff (Loc.U): |
5bf26616 |
2693 | This variable is used internally by Configure to determine the |
781b178c |
2694 | full pathname (if any) of the nroff program. After Configure runs, |
2695 | the value is reset to a plain "nroff" and is not useful. |
2696 | |
a22e52b9 |
2697 | nvsize (perlxv.U): |
2698 | This variable is the size of an NV in bytes. |
2699 | |
2700 | nvtype (perlxv.U): |
2701 | This variable contains the C type used for Perl's NV. |
2702 | |
781b178c |
2703 | o_nonblock (nblock_io.U): |
2704 | This variable bears the symbol value to be used during open() or fcntl() |
2705 | to turn on non-blocking I/O for a file descriptor. If you wish to switch |
2706 | between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead, |
2707 | but that is only supported by some devices. |
2708 | |
2709 | obj_ext (Unix.U): |
2710 | This is an old synonym for _o. |
2711 | |
2712 | old_pthread_create_joinable (d_pthrattrj.U): |
2713 | This variable defines the constant to use for creating joinable |
2714 | (aka undetached) pthreads. Unused if pthread.h defines |
2715 | PTHREAD_CREATE_JOINABLE. If used, possible values are |
2716 | PTHREAD_CREATE_UNDETACHED and __UNDETACHED. |
2717 | |
2718 | optimize (ccflags.U): |
2719 | This variable contains any optimizer/debugger flag that should be used. |
2720 | It is up to the Makefile to use it. |
2721 | |
2722 | orderlib (orderlib.U): |
2723 | This variable is "true" if the components of libraries must be ordered |
2724 | (with `lorder $* | tsort`) before placing them in an archive. Set to |
2725 | "false" if ranlib or ar can generate random libraries. |
2726 | |
2727 | osname (Oldconfig.U): |
2728 | This variable contains the operating system name (e.g. sunos, |
2729 | solaris, hpux, etc.). It can be useful later on for setting |
2730 | defaults. Any spaces are replaced with underscores. It is set |
2731 | to a null string if we can't figure it out. |
2732 | |
2733 | osvers (Oldconfig.U): |
2734 | This variable contains the operating system version (e.g. |
2735 | 4.1.3, 5.2, etc.). It is primarily used for helping select |
2736 | an appropriate hints file, but might be useful elsewhere for |
2737 | setting defaults. It is set to '' if we can't figure it out. |
2738 | We try to be flexible about how much of the version number |
2739 | to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the |
2740 | same for this package, hints files might just be os_4.0 or |
2741 | os_4.1, etc., not keeping separate files for each little release. |
2742 | |
2743 | package (package.U): |
2744 | This variable contains the name of the package being constructed. |
2745 | It is primarily intended for the use of later Configure units. |
2746 | |
2747 | pager (pager.U): |
2748 | This variable contains the name of the preferred pager on the system. |
2749 | Usual values are (the full pathnames of) more, less, pg, or cat. |
2750 | |
2751 | passcat (nis.U): |
2752 | This variable contains a command that produces the text of the |
2753 | /etc/passwd file. This is normally "cat /etc/passwd", but can be |
2754 | "ypcat passwd" when NIS is used. |
aaacdc8b |
2755 | On some systems, such as os390, there may be no equivalent |
2756 | command, in which case this variable is unset. |
781b178c |
2757 | |
2758 | patchlevel (patchlevel.U): |
2759 | The patchlevel level of this package. |
2760 | The value of patchlevel comes from the patchlevel.h file. |
ff935051 |
2761 | In a version number such as 5.6.1, this is the "6". |
c890dc6c |
2762 | In patchlevel.h, this is referred to as "PERL_VERSION". |
781b178c |
2763 | |
2764 | path_sep (Unix.U): |
2765 | This is an old synonym for p_ in Head.U, the character |
2766 | used to separate elements in the command shell search PATH. |
2767 | |
c890dc6c |
2768 | perl5 (perl5.U): |
2769 | This variable contains the full path (if any) to a previously |
2770 | installed perl5.005 or later suitable for running the script |
2771 | to determine inc_version_list. |
2772 | |
781b178c |
2773 | perl (Loc.U): |
c890dc6c |
2774 | This variable is defined but not used by Configure. |
2775 | The value is a plain '' and is not useful. |
781b178c |
2776 | |
ff935051 |
2777 | PERL_REVISION (Oldsyms.U): |
2778 | In a Perl version number such as 5.6.2, this is the 5. |
2779 | This value is manually set in patchlevel.h |
2780 | |
2781 | PERL_SUBVERSION (Oldsyms.U): |
2782 | In a Perl version number such as 5.6.2, this is the 2. |
2783 | Values greater than 50 represent potentially unstable |
2784 | development subversions. |
2785 | This value is manually set in patchlevel.h |
2786 | |
2787 | PERL_VERSION (Oldsyms.U): |
2788 | In a Perl version number such as 5.6.2, this is the 6. |
2789 | This value is manually set in patchlevel.h |
2790 | |
781b178c |
2791 | perladmin (perladmin.U): |
2792 | Electronic mail address of the perl5 administrator. |
2793 | |
2794 | perlpath (perlpath.U): |
2795 | This variable contains the eventual value of the PERLPATH symbol, |
2796 | which contains the name of the perl interpreter to be used in |
2797 | shell scripts and in the "eval 'exec'" idiom. |
2798 | |
2799 | pg (Loc.U): |
5bf26616 |
2800 | This variable is used internally by Configure to determine the |
781b178c |
2801 | full pathname (if any) of the pg program. After Configure runs, |
2802 | the value is reset to a plain "pg" and is not useful. |
2803 | |
2804 | phostname (myhostname.U): |
2805 | This variable contains the eventual value of the PHOSTNAME symbol, |
2806 | which is a command that can be fed to popen() to get the host name. |
2807 | The program should probably not presume that the domain is or isn't |
2808 | there already. |
2809 | |
2810 | pidtype (pidtype.U): |
2811 | This variable defines PIDTYPE to be something like pid_t, int, |
2812 | ushort, or whatever type is used to declare process ids in the kernel. |
2813 | |
2814 | plibpth (libpth.U): |
2815 | Holds the private path used by Configure to find out the libraries. |
2816 | Its value is prepend to libpth. This variable takes care of special |
2817 | machines, like the mips. Usually, it should be empty. |
2818 | |
fe749a9f |
2819 | pm_apiversion (xs_apiversion.U): |
2820 | This variable contains the version of the oldest perl |
2821 | compatible with the present perl. (That is, pure perl modules |
2822 | written for $pm_apiversion will still work for the current |
2823 | version). perl.c:incpush() and lib/lib.pm will automatically |
2824 | search in $sitelib for older directories across major versions |
2825 | back to pm_apiversion. This is only useful if you have a perl |
2826 | library directory tree structured like the default one. The |
2827 | versioned site_perl library was introduced in 5.005, so that's |
2828 | the default setting for this variable. It's hard to imagine |
2829 | it changing before Perl6. It is included here for symmetry |
2830 | with xs_apiveprsion -- the searching algorithms will |
2831 | (presumably) be similar. |
2832 | See the INSTALL file for how this works. |
2833 | |
781b178c |
2834 | pmake (Loc.U): |
2835 | This variable is defined but not used by Configure. |
2836 | The value is a plain '' and is not useful. |
2837 | |
2838 | pr (Loc.U): |
2839 | This variable is defined but not used by Configure. |
2840 | The value is a plain '' and is not useful. |
2841 | |
2842 | prefix (prefix.U): |
2843 | This variable holds the name of the directory below which the |
2844 | user will install the package. Usually, this is /usr/local, and |
2845 | executables go in /usr/local/bin, library stuff in /usr/local/lib, |
2846 | man pages in /usr/local/man, etc. It is only used to set defaults |
2847 | for things in bin.U, mansrc.U, privlib.U, or scriptdir.U. |
2848 | |
2849 | prefixexp (prefix.U): |
2850 | This variable holds the full absolute path of the directory below |
2851 | which the user will install the package. Derived from prefix. |
2852 | |
2853 | privlib (privlib.U): |
2854 | This variable contains the eventual value of the PRIVLIB symbol, |
2855 | which is the name of the private library for this package. It may |
2856 | have a ~ on the front. It is up to the makefile to eventually create |
2857 | this directory while performing installation (with ~ substitution). |
2858 | |
2859 | privlibexp (privlib.U): |
2860 | This variable is the ~name expanded version of privlib, so that you |
2861 | may use it directly in Makefiles or shell scripts. |
2862 | |
2863 | prototype (prototype.U): |
2864 | This variable holds the eventual value of CAN_PROTOTYPE, which |
2865 | indicates the C compiler can handle funciton prototypes. |
2866 | |
2867 | ptrsize (ptrsize.U): |
2868 | This variable contains the value of the PTRSIZE symbol, which |
2869 | indicates to the C program how many bytes there are in a pointer. |
2870 | |
e0a10278 |
2871 | quadkind (quadtype.U): |
0befd8de |
2872 | This variable, if defined, encodes the type of a quad: |
2873 | 1 = int, 2 = long, 3 = long long, 4 = int64_t. |
2874 | |
2875 | quadtype (quadtype.U): |
2876 | This variable defines Quad_t to be something like long, int, |
2877 | long long, int64_t, or whatever type is used for 64-bit integers. |
2878 | |
781b178c |
2879 | randbits (randfunc.U): |
2880 | Indicates how many bits are produced by the function used to |
2881 | generate normalized random numbers. |
2882 | |
2883 | randfunc (randfunc.U): |
2884 | Indicates the name of the random number function to use. |
2885 | Values include drand48, random, and rand. In C programs, |
2886 | the 'Drand01' macro is defined to generate uniformly distributed |
2887 | random numbers over the range [0., 1.[ (see drand01 and nrand). |
2888 | |
2889 | randseedtype (randfunc.U): |
2890 | Indicates the type of the argument of the seedfunc. |
2891 | |
2892 | ranlib (orderlib.U): |
2893 | This variable is set to the pathname of the ranlib program, if it is |
2894 | needed to generate random libraries. Set to ":" if ar can generate |
2895 | random libraries or if random libraries are not supported |
2896 | |
2897 | rd_nodata (nblock_io.U): |
2898 | This variable holds the return code from read() when no data is |
2899 | present. It should be -1, but some systems return 0 when O_NDELAY is |
2900 | used, which is a shame because you cannot make the difference between |
2901 | no data and an EOF.. Sigh! |
2902 | |
c890dc6c |
2903 | revision (patchlevel.U): |
2904 | The value of revision comes from the patchlevel.h file. |
2905 | In a version number such as 5.6.1, this is the "5". |
2906 | In patchlevel.h, this is referred to as "PERL_REVISION". |
2907 | |
781b178c |
2908 | rm (Loc.U): |
5bf26616 |
2909 | This variable is used internally by Configure to determine the |
781b178c |
2910 | full pathname (if any) of the rm program. After Configure runs, |
2911 | the value is reset to a plain "rm" and is not useful. |
2912 | |
2913 | rmail (Loc.U): |
2914 | This variable is defined but not used by Configure. |
2915 | The value is a plain '' and is not useful. |
2916 | |
2917 | runnm (usenm.U): |
2918 | This variable contains 'true' or 'false' depending whether the |
2919 | nm extraction should be performed or not, according to the value |
2920 | of usenm and the flags on the Configure command line. |
2921 | |
2922 | sched_yield (d_pthread_y.U): |
2923 | This variable defines the way to yield the execution |
2924 | of the current thread. |
2925 | |
2926 | scriptdir (scriptdir.U): |
2927 | This variable holds the name of the directory in which the user wants |
2928 | to put publicly scripts for the package in question. It is either |
2929 | the same directory as for binaries, or a special one that can be |
2930 | mounted across different architectures, like /usr/share. Programs |
2931 | must be prepared to deal with ~name expansion. |
2932 | |
2933 | scriptdirexp (scriptdir.U): |
2934 | This variable is the same as scriptdir, but is filename expanded |
2935 | at configuration time, for programs not wanting to bother with it. |
2936 | |
2937 | sed (Loc.U): |
5bf26616 |
2938 | This variable is used internally by Configure to determine the |
781b178c |
2939 | full pathname (if any) of the sed program. After Configure runs, |
2940 | the value is reset to a plain "sed" and is not useful. |
2941 | |
2942 | seedfunc (randfunc.U): |
2943 | Indicates the random number generating seed function. |
2944 | Values include srand48, srandom, and srand. |
2945 | |
2946 | selectminbits (selectminbits.U): |
2947 | This variable holds the minimum number of bits operated by select. |
2948 | That is, if you do select(n, ...), how many bits at least will be |
2949 | cleared in the masks if some activity is detected. Usually this |
2950 | is either n or 32*ceil(n/32), especially many little-endians do |
2951 | the latter. This is only useful if you have select(), naturally. |
2952 | |
2953 | selecttype (selecttype.U): |
2954 | This variable holds the type used for the 2nd, 3rd, and 4th |
2955 | arguments to select. Usually, this is 'fd_set *', if HAS_FD_SET |
2956 | is defined, and 'int *' otherwise. This is only useful if you |
2957 | have select(), naturally. |
2958 | |
2959 | sendmail (Loc.U): |
ff935051 |
2960 | This variable is defined but not used by Configure. |
2961 | The value is a plain '' and is not useful. |

2962 | |
2963 | sh (sh.U): |
2964 | This variable contains the full pathname of the shell used |
2965 | on this system to execute Bourne shell scripts. Usually, this will be |
2966 | /bin/sh, though it's possible that some systems will have /bin/ksh, |
2967 | /bin/pdksh, /bin/ash, /bin/bash, or even something such as |
2968 | D:/bin/sh.exe. |
2969 | This unit comes before Options.U, so you can't set sh with a '-D' |
2970 | option, though you can override this (and startsh) |
2971 | with '-O -Dsh=/bin/whatever -Dstartsh=whatever' |
2972 | |
2973 | shar (Loc.U): |
2974 | This variable is defined but not used by Configure. |
2975 | The value is a plain '' and is not useful. |
2976 | |
2977 | sharpbang (spitshell.U): |

2979 | construct. |
2980 | |
2981 | shmattype (d_shmat.U): |
2982 | This symbol contains the type of pointer returned by shmat(). |
2983 | It can be 'void *' or 'char *'. |
2984 | |
2985 | shortsize (intsize.U): |
2986 | This variable contains the value of the SHORTSIZE symbol which |
2987 | indicates to the C program how many bytes there are in a short. |
2988 | |
2989 | shrpenv (libperl.U): |
2990 | If the user builds a shared libperl.so, then we need to tell the |
2991 | 'perl' executable where it will be able to find the installed libperl.so. |
2992 | One way to do this on some systems is to set the environment variable |
2993 | LD_RUN_PATH to the directory that will be the final location of the |
2994 | shared libperl.so. The makefile can use this with something like |
2995 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
2996 | Typical values are |
2997 | shrpenv="env LD_RUN_PATH=$archlibexp/CORE" |
2998 | or |
2999 | shrpenv='' |
3000 | See the main perl Makefile.SH for actual working usage. |
3001 | Alternatively, we might be able to use a command line option such |
3002 | as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath |
3003 | $archlibexp/CORE (Linux). |
3004 | |
3005 | shsharp (spitshell.U): |
3006 | This variable tells further Configure units whether your sh can |
3007 | handle # comments. |
3008 | |
3009 | sig_count (sig_name.U): |
3010 | This variable holds a number larger than the largest valid |
3011 | signal number. This is usually the same as the NSIG macro. |
3012 | |

3429 | This variable conditionally defines the USE_LONG_DOUBLE symbol, |
3430 | and indicates that long doubles should be used when available. |
3431 | |
1baac590 |
3432 | usemorebits (usemorebits.U): |
3433 | This variable conditionally defines the USE_MORE_BITS symbol, |
3434 | and indicates that explicit 64-bit interfaces and long doubles |
3435 | should be used when available. |
3436 | |
781b178c |
3437 | usemultiplicity (usemultiplicity.U): |
3438 | This variable conditionally defines the MULTIPLICITY symbol, |
3439 | and indicates that Perl should be built to use multiplicity. |
3440 | |
3441 | usemymalloc (mallocsrc.U): |
3442 | This variable contains y if the malloc that comes with this package |
3443 | is desired over the system's version of malloc. People often include |
3444 | special versions of malloc for effiency, but such versions are often |
3445 | less portable. See also mallocsrc and mallocobj. |
3446 | If this is 'y', then -lmalloc is removed from $libs. |
3447 | |
3448 | usenm (usenm.U): |
3449 | This variable contains 'true' or 'false' depending whether the |
3450 | nm extraction is wanted or not. |
3451 | |
3452 | useopcode (Extensions.U): |
3453 | This variable holds either 'true' or 'false' to indicate |
3454 | whether the Opcode extension should be used. The sole |
3455 | use for this currently is to allow an easy mechanism |
3456 | for users to skip the Opcode extension from the Configure |
3457 | command line. |
3458 | |
3459 | useperlio (useperlio.U): |
3460 | This variable conditionally defines the USE_PERLIO symbol, |
3461 | and indicates that the PerlIO abstraction should be |
3462 | used throughout. |
3463 | |
3464 | useposix (Extensions.U): |
3465 | This variable holds either 'true' or 'false' to indicate |
3466 | whether the POSIX extension should be used. The sole |
3467 | use for this currently is to allow an easy mechanism |
3468 | for hints files to indicate that POSIX will not compile |
3469 | on a particular system. |
3470 | |
3471 | usesfio (d_sfio.U): |
3472 | This variable is set to true when the user agrees to use sfio. |
3473 | It is set to false when sfio is not available or when the user |
3474 | explicitely requests not to use sfio. It is here primarily so |
3475 | that command-line settings can override the auto-detection of |
3476 | d_sfio without running into a "WHOA THERE". |
3477 | |
3478 | useshrplib (libperl.U): |
3479 | This variable is set to 'yes' if the user wishes |
3480 | to build a shared libperl, and 'no' otherwise. |
3481 | |
3482 | usesocks (usesocks.U): |
3483 | This variable conditionally defines the USE_SOCKS symbol, |
3484 | and indicates that Perl should be built to use SOCKS. |
3485 | |
3486 | usethreads (usethreads.U): |
3487 | This variable conditionally defines the USE_THREADS symbol, |
3488 | and indicates that Perl should be built to use threads. |
3489 | |
9f50e519 |
3490 | usevendorprefix (vendorprefix.U): |
3491 | This variable tells whether the vendorprefix |
3492 | and consequently other vendor* paths are in use. |
3493 | |
781b178c |
3494 | usevfork (d_vfork.U): |
3495 | This variable is set to true when the user accepts to use vfork. |
3496 | It is set to false when no vfork is available or when the user |
3497 | explicitely requests not to use vfork. |
3498 | |
3499 | usrinc (usrinc.U): |
3500 | This variable holds the path of the include files, which is |
3501 | usually /usr/include. It is mainly used by other Configure units. |
3502 | |
3503 | uuname (Loc.U): |
3504 | This variable is defined but not used by Configure. |
3505 | The value is a plain '' and is not useful. |
3506 | |
a22e52b9 |
3507 | uvoformat (perlxvf.U): |
3508 | This variable contains the format string used for printing |
3509 | a Perl UV as an unsigned octal integer. |
3510 | |
3511 | uvsize (perlxv.U): |
3512 | This variable is the size of a UV in bytes. |

3523 | a Perl UV as an unsigned hexadecimal integer. |
3524 | |
65f19062 |
3525 | vendorarch (vendorarch.U): |
3526 | This variable contains the value of the PERL_VENDORARCH symbol. |
3527 | It may have a ~ on the front. |
3528 | The standard distribution will put nothing in this directory. |
3529 | Vendors who distribute perl may wish to place their own |
3530 | architecture-dependent modules and extensions in this directory with |
3531 | MakeMaker Makefile.PL INSTALLDIRS=vendor |
3532 | or equivalent. See INSTALL for details. |
3533 | |
3534 | vendorarchexp (vendorarch.U): |
3535 | This variable is the ~name expanded version of vendorarch, so that you |
3536 | may use it directly in Makefiles or shell scripts. |
3537 | |
0617aed7 |
3538 | vendorbin (vendorbin.U): |
f868067f |
3539 | This variable contains the eventual value of the VENDORBIN symbol. |
3540 | It may have a ~ on the front. |
3541 | The standard distribution will put nothing in this directory. |
3542 | Vendors who distribute perl may wish to place additional |
3543 | binaries in this directory with |
3544 | MakeMaker Makefile.PL INSTALLDIRS=vendor |
3545 | or equivalent. See INSTALL for details. |
0617aed7 |
3546 | |
3547 | vendorbinexp (vendorbin.U): |
3548 | This variable is the ~name expanded version of vendorbin, so that you |
3549 | may use it directly in Makefiles or shell scripts. |
3550 | |
a3635516 |
3551 | vendorlib (vendorlib.U): |
3552 | This variable contains the eventual value of the VENDORLIB symbol, |
f868067f |
3553 | which is the name of the private library for this package. |
3554 | The standard distribution will put nothing in this directory. |
3555 | Vendors who distribute perl may wish to place their own |
3556 | modules in this directory with |
3557 | MakeMaker Makefile.PL INSTALLDIRS=vendor |
3558 | or equivalent. See INSTALL for details. |
a3635516 |
3559 | |
65f19062 |
3560 | vendorlib_stem (vendorlib.U): |
3561 | This variable is $vendorlibexp with any trailing version-specific component |
3562 | removed. The elements in inc_version_list (inc_version_list.U) can |
3563 | be tacked onto this variable to generate a list of directories to search. |
3564 | |
a3635516 |
3565 | vendorlibexp (vendorlib.U): |
3566 | This variable is the ~name expanded version of vendorlib, so that you |
3567 | may use it directly in Makefiles or shell scripts. |
3568 | |
3569 | vendorprefix (vendorprefix.U): |
3570 | This variable holds the full absolute path of the directory below |
3571 | which the vendor will install add-on packages. |
f868067f |
3572 | See INSTALL for usage and examples. |
a3635516 |
3573 | |
3574 | vendorprefixexp (vendorprefix.U): |
3575 | This variable holds the full absolute path of the directory below |
3576 | which the vendor will install add-on packages. Derived from vendorprefix. |
3577 | |
781b178c |
3578 | version (patchlevel.U): |
ff935051 |
3579 | The full version number of this package, such as 5.6.1 (or 5_6_1). |
c890dc6c |
3580 | This combines revision, patchlevel, and subversion to get the |
ff935051 |
3581 | full version number, including any possible subversions. |
3582 | This is suitable for use as a directory name, and hence is |
3583 | filesystem dependent. |
781b178c |
3584 | |
3585 | vi (Loc.U): |
3586 | This variable is defined but not used by Configure. |
3587 | The value is a plain '' and is not useful. |
3588 | |
3589 | voidflags (voidflags.U): |
3590 | This variable contains the eventual value of the VOIDFLAGS symbol, |
3591 | which indicates how much support of the void type is given by this |
3592 | compiler. See VOIDFLAGS for more info. |
3593 | |
3594 | xlibpth (libpth.U): |
3595 | This variable holds extra path (space-separated) used to find |
3596 | libraries on this platform, for example CPU-specific libraries |
3597 | (on multi-CPU platforms) may be listed here. |
3598 | |
fe749a9f |
3599 | xs_apiversion (xs_apiversion.U): |
3600 | This variable contains the version of the oldest perl binary |
3601 | compatible with the present perl. perl.c:incpush() and |
3602 | lib/lib.pm will automatically search in $sitearch for older |
3603 | directories across major versions back to xs_apiversion. |
3604 | This is only useful if you have a perl library directory tree |
3605 | structured like the default one. |
3606 | See INSTALL for how this works. |
3607 | The versioned site_perl directory was introduced in 5.005, |
3608 | so that is the lowest possible value. |
3609 | Since this can depend on compile time options (such as |
3610 | bincompat) it is set by Configure. Other non-default sources |
3611 | of potential incompatibility, such as multiplicity, threads, |
3612 | debugging, 64bits, sfio, etc., are not checked for currently, |
3613 | though in principle we could go snooping around in old |
3614 | Config.pm files. |
3615 | |
781b178c |
3616 | zcat (Loc.U): |
3617 | This variable is defined but not used by Configure. |
3618 | The value is a plain '' and is not useful. |
3619 | |
3620 | zip (Loc.U): |
5bf26616 |
3621 | This variable is used internally by Configure to determine the |
781b178c |
3622 | full pathname (if any) of the zip program. After Configure runs, |
3623 | the value is reset to a plain "zip" and is not useful. |
3624 | |
