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 |
29 | double. Usual values are 2, 4 and 8. |
30 | |
31 | ansi2knr (ansi2knr.U): |
32 | This variable is set if the user needs to run ansi2knr. |
33 | Currently, this is not supported, so we just abort. |
34 | |
35 | aphostname (d_gethname.U): |
36 | This variable contains the command which can be used to compute the |
37 | host name. The command is fully qualified by its absolute path, to make |
38 | it safe when used by a process with super-user privileges. |
39 | |
40 | apiversion (patchlevel.U): |
5bf26616 |
41 | MakeMaker will install add-on modules in a directory with the |
42 | PERL_APIVERSION version number. The value is set manually in |
43 | patchlevel.h. Normally, for maintenance releases, this is |
44 | just something like 5.005 or 5.6 or 5.7. That is, it does not |
45 | include the subversion number and does not change across |
46 | maintenance releases. This is so that add-on extensions can |
47 | be shared across maintenance versions. It is unclear how this |
48 | ought to work for developer versions. If a release breaks |
49 | binary compatibility, this number should be increased. |

74 | archobjs (Unix.U): |
75 | This variable defines any additional objects that must be linked |
76 | in with the program on this architecture. On unix, it is usually |
77 | empty. It is typically used to include emulations of unix calls |

2051 | |
2052 | inews (Loc.U): |

2054 | The value is a plain '' and is not useful. |
2055 | |
2056 | installarchlib (archlib.U): |
2057 | This variable is really the same as archlibexp but may differ on |
2058 | those systems using AFS. For extra portability, only this variable |
2059 | should be used in makefiles. |
2060 | |
2061 | installbin (bin.U): |
2062 | This variable is the same as binexp unless AFS is running in which case |
2063 | the user is explicitely prompted for it. This variable should always |
2064 | be used in your makefiles for maximum portability. |
2065 | |
2066 | installman1dir (man1dir.U): |
2067 | This variable is really the same as man1direxp, unless you are using |
2068 | AFS in which case it points to the read/write location whereas |
2069 | man1direxp only points to the read-only access location. For extra |
2070 | portability, you should only use this variable within your makefiles. |
2071 | |
2072 | installman3dir (man3dir.U): |
2073 | This variable is really the same as man3direxp, unless you are using |
2074 | AFS in which case it points to the read/write location whereas |
2075 | man3direxp only points to the read-only access location. For extra |
2076 | portability, you should only use this variable within your makefiles. |
2077 | |
2078 | installprefix (installprefix.U): |
2079 | This variable holds the name of the directory below which |
2080 | "make install" will install the package. For most users, this |
2081 | is the same as prefix. However, it is useful for |
2082 | installing the software into a different (usually temporary) |
2083 | location after which it can be bundled up and moved somehow |
2084 | to the final location specified by prefix. |
2085 | |
2086 | installprefixexp (installprefix.U): |
2087 | This variable holds the full absolute path of installprefix |
2088 | with all ~-expansion done. |
2089 | |
2090 | installprivlib (privlib.U): |
2091 | This variable is really the same as privlibexp but may differ on |
2092 | those systems using AFS. For extra portability, only this variable |
2093 | should be used in makefiles. |
2094 | |
2095 | installscript (scriptdir.U): |
2096 | This variable is usually the same as scriptdirexp, unless you are on |
2097 | a system running AFS, in which case they may differ slightly. You |
2098 | should always use this variable within your makefiles for portability. |
2099 | |
2100 | installsitearch (sitearch.U): |
2101 | This variable is really the same as sitearchexp but may differ on |
2102 | those systems using AFS. For extra portability, only this variable |

2104 | |
2105 | installsitelib (sitelib.U): |
2106 | This variable is really the same as sitelibexp but may differ on |
2107 | those systems using AFS. For extra portability, only this variable |
2108 | should be used in makefiles. |
2109 | |
2110 | installstyle (installstyle.U): |
2111 | This variable describes the "style" of the perl installation. |
2112 | This is intended to be useful for tools that need to |
2113 | manipulate entire perl distributions. Perl itself doesn't use |
2114 | this to find its libraries -- the library directories are |
2115 | stored directly in Config.pm. Currently, there are only two |
2116 | styles: "lib" and "lib/perl5". The default library locations |
2117 | (e.g. privlib, sitelib) are either $prefix/lib or |
2118 | $prefix/lib/perl5. The former is useful if $prefix is a |
2119 | directory dedicated to perl (e.g. /opt/perl), while the latter |
2120 | is useful if $prefix is shared by many packages, e.g. if |
2121 | $prefix=/usr/local. |
2122 | This may later be extended to include other information, so |
2123 | be careful with pattern-matching on the results. |
2124 | For compatibility with perl5.005 and earlier, the default |
2125 | setting is based on whether or not $prefix contains the string |
2126 | "perl". |
2127 | |
2128 | installusrbinperl (instubperl.U): |
2129 | This variable tells whether Perl should be installed also as |
2130 | /usr/bin/perl in addition to |
2131 | $installbin/perl |
2132 | |
a3635516 |
2133 | installvendorlib (vendorlib.U): |
2134 | This variable is really the same as vendorlibexp but may differ on |
2135 | those systems using AFS. For extra portability, only this variable |
2136 | should be used in makefiles. |
2137 | |
781b178c |
2138 | intsize (intsize.U): |
2139 | This variable contains the value of the INTSIZE symbol, which |

2151 | This variable contains a flag which will tell the C compiler and loader |
2152 | to produce a program running with a large memory model. It is up to |
2153 | the Makefile to use this. |
2154 | |
2155 | ld (dlsrc.U): |
2156 | This variable indicates the program to be used to link |
2157 | libraries for dynamic loading. On some systems, it is 'ld'. |
2158 | On ELF systems, it should be $cc. Mostly, we'll try to respect |
2159 | the hint file setting. |
2160 | |
2161 | lddlflags (dlsrc.U): |
2162 | This variable contains any special flags that might need to be |
2163 | passed to $ld to create a shared library suitable for dynamic |
2164 | loading. It is up to the makefile to use it. For hpux, it |
2165 | should be '-b'. For sunos 4.1, it is empty. |
2166 | |
2167 | ldflags (ccflags.U): |
2168 | This variable contains any additional C loader flags desired by |
2169 | the user. It is up to the Makefile to use this. |
2170 | |

2172 | This variable holds the name of the shared library |
2173 | search path, often LD_LIBRARY_PATH. To get an empty |
2174 | string, the hints file must set this to 'none'. |
2175 | |
2176 | less (Loc.U): |
5bf26616 |
2177 | This variable is used internally by Configure to determine the |
781b178c |
2178 | full pathname (if any) of the less program. After Configure runs, |
2179 | the value is reset to a plain "less" and is not useful. |
2180 | |
2181 | lib_ext (Unix.U): |
2182 | This is an old synonym for _a. |
2183 | |
2184 | libc (libc.U): |
2185 | This variable contains the location of the C library. |
2186 | |
2187 | libperl (libperl.U): |
2188 | The perl executable is obtained by linking perlmain.c with |
2189 | libperl, any static extensions (usually just DynaLoader), |
2190 | and any other libraries needed on this system. libperl |
2191 | is usually libperl.a, but can also be libperl.so.xxx if |
2192 | the user wishes to build a perl executable with a shared |
2193 | library. |
2194 | |
2195 | libpth (libpth.U): |
2196 | This variable holds the general path (space-separated) used to find |
2197 | libraries. It is intended to be used by other units. |
2198 | |
2199 | libs (libs.U): |
2200 | This variable holds the additional libraries we want to use. |
2201 | It is up to the Makefile to deal with it. |
2202 | |
2203 | libswanted (Myinit.U): |
2204 | This variable holds a list of all the libraries we want to |
2205 | search. The order is chosen to pick up the c library |
2206 | ahead of ucb or bsd libraries for SVR4. |
2207 | |
2208 | line (Loc.U): |
2209 | This variable is defined but not used by Configure. |
2210 | The value is a plain '' and is not useful. |
2211 | |
2212 | lint (Loc.U): |

2214 | The value is a plain '' and is not useful. |
2215 | |
2216 | lkflags (ccflags.U): |
2217 | This variable contains any additional C partial linker flags desired by |
2218 | the user. It is up to the Makefile to use this. |
2219 | |
2220 | ln (Loc.U): |
5bf26616 |
2221 | This variable is used internally by Configure to determine the |
781b178c |
2222 | full pathname (if any) of the ln program. After Configure runs, |
2223 | the value is reset to a plain "ln" and is not useful. |
2224 | |
2225 | lns (lns.U): |
2226 | This variable holds the name of the command to make |
2227 | symbolic links (if they are supported). It can be used |
2228 | in the Makefile. It is either 'ln -s' or 'ln' |
2229 | |
2230 | locincpth (ccflags.U): |
2231 | This variable contains a list of additional directories to be |
2232 | searched by the compiler. The appropriate '-I' directives will |
2233 | be added to ccflags. This is intended to simplify setting |
2234 | local directories from the Configure command line. |
2235 | It's not much, but it parallels the loclibpth stuff in libpth.U. |
2236 | |
2237 | loclibpth (libpth.U): |
2238 | This variable holds the paths (space-separated) used to find local |
2239 | libraries. It is prepended to libpth, and is intended to be easily |
2240 | set from the command line. |
2241 | |
2242 | longdblsize (d_longdbl.U): |
2243 | This variable contains the value of the LONG_DOUBLESIZE symbol, which |

2248 | This variable contains the value of the LONGLONGSIZE symbol, which |
2249 | indicates to the C program how many bytes there are in a long long, |
2250 | if this system supports long long. |
2251 | |
2252 | longsize (intsize.U): |
2253 | This variable contains the value of the LONGSIZE symbol, which |
2254 | indicates to the C program how many bytes there are in a long. |

2268 | |
2269 | lseeksize (lseektype.U): |
2270 | This variable defines lseektype to be something like off_t, long, |
2271 | or whatever type is used to declare lseek offset's type in the |

2273 | |
2274 | lseektype (lseektype.U): |
2275 | This variable defines lseektype to be something like off_t, long, |
2276 | or whatever type is used to declare lseek offset's type in the |

2290 | the value is reset to a plain "make" and is not useful. |
2291 | |
2292 | make_set_make (make.U): |
2293 | Some versions of 'make' set the variable MAKE. Others do not. |
2294 | This variable contains the string to be included in Makefile.SH |
2295 | so that MAKE is set if needed, and not if not needed. |
2296 | Possible values are: |
2297 | make_set_make='#' # If your make program handles this for you, |
2298 | make_set_make="MAKE=$make" # if it doesn't. |
2299 | I used a comment character so that we can distinguish a |
2300 | 'set' value (from a previous config.sh or Configure '-D' option) |
2301 | from an uncomputed value. |
2302 | |
2303 | mallocobj (mallocsrc.U): |
2304 | This variable contains the name of the malloc.o that this package |
2305 | generates, if that malloc.o is preferred over the system malloc. |

2313 | Makefiles. |
2314 | |

2323 | |
2324 | man1direxp (man1dir.U): |

2338 | |
2339 | man3direxp (man3dir.U): |
2340 | This variable is the same as the man3dir variable, but is filename |
2341 | expanded at configuration time, for convenient use in makefiles. |
2342 | |
2343 | man3ext (man3dir.U): |
2344 | This variable contains the extension that the manual page should |
2345 | have: one of 'n', 'l', or '3'. The Makefile must supply the '.'. |
2346 | See man3dir. |
2347 | |
2348 | Mcc (Loc.U): |
5bf26616 |
2349 | This variable is used internally by Configure to determine the |
781b178c |
2350 | full pathname (if any) of the Mcc program. After Configure runs, |
2351 | the value is reset to a plain "Mcc" and is not useful. |
2352 | |
2353 | medium (models.U): |
2354 | This variable contains a flag which will tell the C compiler and loader |
2355 | to produce a program running with a medium memory model. If the |
2356 | medium model is not supported, contains the flag to produce large |
2357 | model programs. It is up to the Makefile to use this. |
2358 | |
2359 | mips_type (usrinc.U): |
2360 | This variable holds the environment type for the mips system. |
2361 | Possible values are "BSD 4.3" and "System V". |
2362 | |

5bf26616 |
2384 | This variable is used internally by Configure to determine the |

2396 | |
2397 | myarchname (archname.U): |
2398 | This variable holds the architecture name computed by Configure in |
2399 | a previous run. It is not intended to be perused by any user and |
2400 | should never be set in a hint file. |
2401 | |
2402 | mydomain (myhostname.U): |
2403 | This variable contains the eventual value of the MYDOMAIN symbol, |
2404 | which is the domain of the host the program is going to run on. |
2405 | The domain must be appended to myhostname to form a complete host name. |
2406 | The dot comes with mydomain, and need not be supplied by the program. |
2407 | |
2408 | myhostname (myhostname.U): |
2409 | This variable contains the eventual value of the MYHOSTNAME symbol, |
2410 | which is the name of the host the program is going to run on. |
2411 | The domain is not kept with hostname, but must be gotten from mydomain. |
2412 | The dot comes with mydomain, and need not be supplied by the program. |
2413 | |
2414 | myuname (Oldconfig.U): |
2415 | The output of 'uname -a' if available, otherwise the hostname. On Xenix, |
2416 | pseudo variables assignments in the output are stripped, thank you. The |
2417 | whole thing is then lower-cased. |
2418 | |
2419 | n (n.U): |
2420 | This variable contains the '-n' flag if that is what causes the echo |
2421 | command to suppress newline. Otherwise it is null. Correct usage is |
2422 | $echo $n "prompt for a question: $c". |
2423 | |
2424 | netdb_hlen_type (netdbtype.U): |
2425 | This variable holds the type used for the 2nd argument to |
2426 | gethostbyaddr(). Usually, this is int or size_t or unsigned. |

2428 | |
2429 | netdb_host_type (netdbtype.U): |
2430 | This variable holds the type used for the 1st argument to |
2431 | gethostbyaddr(). Usually, this is char * or void *, possibly |
2432 | with or without a const prefix. |
2433 | This is only useful if you have gethostbyaddr(), naturally. |
2434 | |
2435 | netdb_name_type (netdbtype.U): |
2436 | This variable holds the type used for the argument to |
2437 | gethostbyname(). Usually, this is char * or const char *. |
2438 | This is only useful if you have gethostbyname(), naturally. |
2439 | |
2440 | netdb_net_type (netdbtype.U): |
2441 | This variable holds the type used for the 1st argument to |
2442 | getnetbyaddr(). Usually, this is int or long. |
2443 | This is only useful if you have getnetbyaddr(), naturally. |
2444 | |
2445 | nm (Loc.U): |
5bf26616 |
2446 | This variable is used internally by Configure to determine the |
781b178c |
2447 | full pathname (if any) of the nm program. After Configure runs, |
2448 | the value is reset to a plain "nm" and is not useful. |
2449 | |
2450 | nm_opt (usenm.U): |
2451 | This variable holds the options that may be necessary for nm. |
2452 | |
2453 | nm_so_opt (usenm.U): |
2454 | This variable holds the options that may be necessary for nm |
2455 | to work on a shared library but that can not be used on an |
2456 | archive library. Currently, this is only used by Linux, where |
2457 | nm --dynamic is *required* to get symbols from an ELF library which |
2458 | has been stripped, but nm --dynamic is *fatal* on an archive library. |
2459 | Maybe Linux should just always set usenm=false. |
2460 | |
2461 | nonxs_ext (Extensions.U): |
2462 | This variable holds a list of all non-xs extensions included |
2463 | in the package. All of them will be built. |
2464 | |
2465 | nroff (Loc.U): |
5bf26616 |
2466 | This variable is used internally by Configure to determine the |
781b178c |
2467 | full pathname (if any) of the nroff program. After Configure runs, |
2468 | the value is reset to a plain "nroff" and is not useful. |
2469 | |
2470 | o_nonblock (nblock_io.U): |
2471 | This variable bears the symbol value to be used during open() or fcntl() |
2472 | to turn on non-blocking I/O for a file descriptor. If you wish to switch |
2473 | between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead, |
2474 | but that is only supported by some devices. |
2475 | |
2476 | obj_ext (Unix.U): |
2477 | This is an old synonym for _o. |
2478 | |
2479 | old_pthread_create_joinable (d_pthrattrj.U): |
2480 | This variable defines the constant to use for creating joinable |
2481 | (aka undetached) pthreads. Unused if pthread.h defines |
2482 | PTHREAD_CREATE_JOINABLE. If used, possible values are |
2483 | PTHREAD_CREATE_UNDETACHED and __UNDETACHED. |
2484 | |
2485 | optimize (ccflags.U): |
2486 | This variable contains any optimizer/debugger flag that should be used. |
2487 | It is up to the Makefile to use it. |
2488 | |
2489 | orderlib (orderlib.U): |
2490 | This variable is "true" if the components of libraries must be ordered |
2491 | (with `lorder $* | tsort`) before placing them in an archive. Set to |
2492 | "false" if ranlib or ar can generate random libraries. |
2493 | |
2494 | osname (Oldconfig.U): |
2495 | This variable contains the operating system name (e.g. sunos, |
2496 | solaris, hpux, etc.). It can be useful later on for setting |
2497 | defaults. Any spaces are replaced with underscores. It is set |
2498 | to a null string if we can't figure it out. |
2499 | |
2500 | osvers (Oldconfig.U): |
2501 | This variable contains the operating system version (e.g. |
2502 | 4.1.3, 5.2, etc.). It is primarily used for helping select |
2503 | an appropriate hints file, but might be useful elsewhere for |
2504 | setting defaults. It is set to '' if we can't figure it out. |
2505 | We try to be flexible about how much of the version number |
2506 | to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the |
2507 | same for this package, hints files might just be os_4.0 or |
2508 | os_4.1, etc., not keeping separate files for each little release. |
2509 | |
2510 | package (package.U): |
2511 | This variable contains the name of the package being constructed. |
2512 | It is primarily intended for the use of later Configure units. |
2513 | |
2514 | pager (pager.U): |
2515 | This variable contains the name of the preferred pager on the system. |
2516 | Usual values are (the full pathnames of) more, less, pg, or cat. |
2517 | |
2518 | passcat (nis.U): |
2519 | This variable contains a command that produces the text of the |
2520 | /etc/passwd file. This is normally "cat /etc/passwd", but can be |
2521 | "ypcat passwd" when NIS is used. |
2522 | |
2523 | patchlevel (patchlevel.U): |
2524 | The patchlevel level of this package. |
2525 | The value of patchlevel comes from the patchlevel.h file. |
2526 | |
2527 | path_sep (Unix.U): |
2528 | This is an old synonym for p_ in Head.U, the character |
2529 | used to separate elements in the command shell search PATH. |
2530 | |
2531 | perl (Loc.U): |
2532 | This variable is defined but not used by Configure. |
2533 | The value is a plain '' and is not useful. |

2540 | which contains the name of the perl interpreter to be used in |
2541 | shell scripts and in the "eval 'exec'" idiom. |
2542 | |
2543 | pg (Loc.U): |
5bf26616 |
2544 | This variable is used internally by Configure to determine the |
781b178c |
2545 | full pathname (if any) of the pg program. After Configure runs, |
2546 | the value is reset to a plain "pg" and is not useful. |
2547 | |
2548 | phostname (myhostname.U): |
2549 | This variable contains the eventual value of the PHOSTNAME symbol, |
2550 | which is a command that can be fed to popen() to get the host name. |
2551 | The program should probably not presume that the domain is or isn't |
2552 | there already. |
2553 | |
2554 | pidtype (pidtype.U): |
2555 | This variable defines PIDTYPE to be something like pid_t, int, |
2556 | ushort, or whatever type is used to declare process ids in the kernel. |
2557 | |
2558 | plibpth (libpth.U): |
2559 | Holds the private path used by Configure to find out the libraries. |
2560 | Its value is prepend to libpth. This variable takes care of special |
2561 | machines, like the mips. Usually, it should be empty. |
2562 | |
75347591 |
2563 | pm_apiversion (xs_apiversion.U): |
2564 | This variable contains the version of the oldest perl |
2565 | compatible with the present perl. (That is, pure perl modules |
2566 | written for $pm_apiversion will still work for the current |
2567 | version). perl.c:incpush() and lib/lib.pm will automatically |
2568 | search in $sitelib for older directories across major versions |
2569 | back to pm_apiversion. This is only useful if you have a perl |
2570 | library directory tree structured like the default one. The |
2571 | versioned site_perl library was introduced in 5.005, so that's |
2572 | the default setting for this variable. It's hard to imagine |
2573 | it changing before Perl6. It is included here for symmetry |
2574 | with xs_apiveprsion -- the searching algorithms will |
2575 | (presumably) be similar. |
2576 | See the INSTALL file for how this works. |
2577 | |
781b178c |
2578 | pmake (Loc.U): |
2579 | This variable is defined but not used by Configure. |
2580 | The value is a plain '' and is not useful. |
2581 | |
2582 | pr (Loc.U): |
2583 | This variable is defined but not used by Configure. |
2584 | The value is a plain '' and is not useful. |
2585 | |
2586 | prefix (prefix.U): |
2587 | This variable holds the name of the directory below which the |
2588 | user will install the package. Usually, this is /usr/local, and |
2589 | executables go in /usr/local/bin, library stuff in /usr/local/lib, |
2590 | man pages in /usr/local/man, etc. It is only used to set defaults |
2591 | for things in bin.U, mansrc.U, privlib.U, or scriptdir.U. |
2592 | |
2593 | prefixexp (prefix.U): |
2594 | This variable holds the full absolute path of the directory below |
2595 | which the user will install the package. Derived from prefix. |
2596 | |
2597 | privlib (privlib.U): |
2598 | This variable contains the eventual value of the PRIVLIB symbol, |
2599 | which is the name of the private library for this package. It may |
2600 | have a ~ on the front. It is up to the makefile to eventually create |
2601 | this directory while performing installation (with ~ substitution). |
2602 | |
2603 | privlibexp (privlib.U): |
2604 | This variable is the ~name expanded version of privlib, so that you |
2605 | may use it directly in Makefiles or shell scripts. |
2606 | |
2607 | prototype (prototype.U): |
2608 | This variable holds the eventual value of CAN_PROTOTYPE, which |
2609 | indicates the C compiler can handle funciton prototypes. |
2610 | |
2611 | ptrsize (ptrsize.U): |
2612 | This variable contains the value of the PTRSIZE symbol, which |
2613 | indicates to the C program how many bytes there are in a pointer. |
2614 | |
2615 | randbits (randfunc.U): |
2616 | Indicates how many bits are produced by the function used to |
2617 | generate normalized random numbers. |
2618 | |
2619 | randfunc (randfunc.U): |
2620 | Indicates the name of the random number function to use. |
2621 | Values include drand48, random, and rand. In C programs, |
2622 | the 'Drand01' macro is defined to generate uniformly distributed |
2623 | random numbers over the range [0., 1.[ (see drand01 and nrand). |
2624 | |
2625 | randseedtype (randfunc.U): |
2626 | Indicates the type of the argument of the seedfunc. |
2627 | |
2628 | ranlib (orderlib.U): |
2629 | This variable is set to the pathname of the ranlib program, if it is |
2630 | needed to generate random libraries. Set to ":" if ar can generate |
2631 | random libraries or if random libraries are not supported |
2632 | |
2633 | rd_nodata (nblock_io.U): |
2634 | This variable holds the return code from read() when no data is |
2635 | present. It should be -1, but some systems return 0 when O_NDELAY is |
2636 | used, which is a shame because you cannot make the difference between |
2637 | no data and an EOF.. Sigh! |
2638 | |
2639 | rm (Loc.U): |
5bf26616 |
2640 | This variable is used internally by Configure to determine the |
781b178c |
2641 | full pathname (if any) of the rm program. After Configure runs, |
2642 | the value is reset to a plain "rm" and is not useful. |
2643 | |
2644 | rmail (Loc.U): |
2645 | This variable is defined but not used by Configure. |
2646 | The value is a plain '' and is not useful. |
2647 | |
2648 | runnm (usenm.U): |
2649 | This variable contains 'true' or 'false' depending whether the |
2650 | nm extraction should be performed or not, according to the value |
2651 | of usenm and the flags on the Configure command line. |
2652 | |
2653 | sched_yield (d_pthread_y.U): |
2654 | This variable defines the way to yield the execution |
2655 | of the current thread. |
2656 | |
2657 | scriptdir (scriptdir.U): |
2658 | This variable holds the name of the directory in which the user wants |
2659 | to put publicly scripts for the package in question. It is either |
2660 | the same directory as for binaries, or a special one that can be |
2661 | mounted across different architectures, like /usr/share. Programs |
2662 | must be prepared to deal with ~name expansion. |
2663 | |
2664 | scriptdirexp (scriptdir.U): |

2667 | |
2668 | sed (Loc.U): |
5bf26616 |
2669 | This variable is used internally by Configure to determine the |
781b178c |
2670 | full pathname (if any) of the sed program. After Configure runs, |
2671 | the value is reset to a plain "sed" and is not useful. |
2672 | |
2673 | seedfunc (randfunc.U): |
2674 | Indicates the random number generating seed function. |

2676 | |
2677 | selectminbits (selectminbits.U): |
2678 | This variable holds the minimum number of bits operated by select. |
2679 | That is, if you do select(n, ...), how many bits at least will be |
2680 | cleared in the masks if some activity is detected. Usually this |
2681 | is either n or 32*ceil(n/32), especially many little-endians do |
2682 | the latter. This is only useful if you have select(), naturally. |
2683 | |
2684 | selecttype (selecttype.U): |
2685 | This variable holds the type used for the 2nd, 3rd, and 4th |
2686 | arguments to select. Usually, this is 'fd_set *', if HAS_FD_SET |
2687 | is defined, and 'int *' otherwise. This is only useful if you |
2688 | have select(), naturally. |
2689 | |
2690 | sendmail (Loc.U): |

2695 | This variable contains the full pathname of the shell used |
2696 | on this system to execute Bourne shell scripts. Usually, this will be |
2697 | /bin/sh, though it's possible that some systems will have /bin/ksh, |
2698 | /bin/pdksh, /bin/ash, /bin/bash, or even something such as |
2699 | D:/bin/sh.exe. |
2700 | This unit comes before Options.U, so you can't set sh with a '-D' |
2701 | option, though you can override this (and startsh) |
2702 | with '-O -Dsh=/bin/whatever -Dstartsh=whatever' |
2703 | |
2704 | shar (Loc.U): |
2705 | This variable is defined but not used by Configure. |

2721 | If the user builds a shared libperl.so, then we need to tell the |
2722 | 'perl' executable where it will be able to find the installed libperl.so. |
2723 | One way to do this on some systems is to set the environment variable |
2724 | LD_RUN_PATH to the directory that will be the final location of the |
2725 | shared libperl.so. The makefile can use this with something like |
2726 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
2727 | Typical values are |
2728 | shrpenv="env LD_RUN_PATH=$archlibexp/CORE" |
2729 | or |
2730 | shrpenv='' |
2731 | See the main perl Makefile.SH for actual working usage. |
2732 | Alternatively, we might be able to use a command line option such |
2733 | as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath |
2734 | $archlibexp/CORE (Linux). |
2735 | |

3095 | |
3096 | useposix (Extensions.U): |
3097 | This variable holds either 'true' or 'false' to indicate |
3098 | whether the POSIX extension should be used. The sole |
3099 | use for this currently is to allow an easy mechanism |
3100 | for hints files to indicate that POSIX will not compile |
3101 | on a particular system. |
3102 | |
3103 | usesfio (d_sfio.U): |
3104 | This variable is set to true when the user agrees to use sfio. |
3105 | It is set to false when sfio is not available or when the user |
3106 | explicitely requests not to use sfio. It is here primarily so |
3107 | that command-line settings can override the auto-detection of |
3108 | d_sfio without running into a "WHOA THERE". |
3109 | |
3110 | useshrplib (libperl.U): |
3111 | This variable is set to 'yes' if the user wishes |
3112 | to build a shared libperl, and 'no' otherwise. |
3113 | |
3114 | usesocks (usesocks.U): |
3115 | This variable conditionally defines the USE_SOCKS symbol, |
3116 | and indicates that Perl should be built to use SOCKS. |
3117 | |
3118 | usethreads (usethreads.U): |
3119 | This variable conditionally defines the USE_THREADS symbol, |
3120 | and indicates that Perl should be built to use threads. |
3121 | |
9f50e519 |
3122 | usevendorprefix (vendorprefix.U): |
3123 | This variable tells whether the vendorprefix |
3124 | and consequently other vendor* paths are in use. |
3125 | |
781b178c |
3126 | usevfork (d_vfork.U): |
3127 | This variable is set to true when the user accepts to use vfork. |
3128 | It is set to false when no vfork is available or when the user |
3129 | explicitely requests not to use vfork. |
3130 | |
3131 | usrinc (usrinc.U): |
3132 | This variable holds the path of the include files, which is |
3133 | usually /usr/include. It is mainly used by other Configure units. |
3134 | |
3135 | uuname (Loc.U): |
3136 | This variable is defined but not used by Configure. |
3137 | The value is a plain '' and is not useful. |
3138 | |
a3635516 |
3139 | vendorlib (vendorlib.U): |
3140 | This variable contains the eventual value of the VENDORLIB symbol, |
3141 | which is the name of the private library for this package. It may |
3142 | have a ~ on the front. It is up to the makefile to eventually create |
3143 | this directory while performing installation (with ~ substitution). |
3144 | Vendors who distribute perl binaries may place their own |
3145 | extensions and modules in this directory. |
3146 | |
3147 | vendorlibexp (vendorlib.U): |
3148 | This variable is the ~name expanded version of vendorlib, so that you |
3149 | may use it directly in Makefiles or shell scripts. |
3150 | |
3151 | vendorprefix (vendorprefix.U): |
3152 | This variable holds the full absolute path of the directory below |
3153 | which the vendor will install add-on packages. |
3154 | |
3155 | vendorprefixexp (vendorprefix.U): |
3156 | This variable holds the full absolute path of the directory below |
3157 | which the vendor will install add-on packages. Derived from vendorprefix. |
3158 | |
781b178c |
3159 | version (patchlevel.U): |
3160 | The full version number of this package. This combines |
3161 | baserev, patchlevel, and subversion to get the full |
3162 | version number, including any possible subversions. Care |
3163 | is taken to use the C locale in order to get something |
3164 | like 5.004 instead of 5,004. This is unique to perl. |
3165 | |
3166 | vi (Loc.U): |
3167 | This variable is defined but not used by Configure. |
3168 | The value is a plain '' and is not useful. |
3169 | |
3170 | voidflags (voidflags.U): |
3171 | This variable contains the eventual value of the VOIDFLAGS symbol, |
3172 | which indicates how much support of the void type is given by this |
3173 | compiler. See VOIDFLAGS for more info. |
3174 | |
3175 | xlibpth (libpth.U): |
3176 | This variable holds extra path (space-separated) used to find |
3177 | libraries on this platform, for example CPU-specific libraries |
3178 | (on multi-CPU platforms) may be listed here. |
3179 | |
75347591 |
3180 | xs_apiversion (xs_apiversion.U): |
3181 | This variable contains the version of the oldest perl binary |
3182 | compatible with the present perl. perl.c:incpush() and |
3183 | lib/lib.pm will automatically search in $sitearch for older |
3184 | directories across major versions back to xs_apiversion. |
3185 | This is only useful if you have a perl library directory tree |
3186 | structured like the default one. |
3187 | See INSTALL for how this works. |
3188 | The versioned site_perl directory was introduced in 5.005, |
3189 | so that is the lowest possible value. |
3190 | Since this can depend on compile time options (such as |
3191 | bincompat) it is set by Configure. Other non-default sources |
3192 | of potential incompatibility, such as multiplicity, threads, |
3193 | debugging, 64bits, sfio, etc., are not checked for currently, |
3194 | though in principle we could go snooping around in old |
3195 | Config.pm files. |
3196 | |
781b178c |
3197 | zcat (Loc.U): |
3198 | This variable is defined but not used by Configure. |
3199 | The value is a plain '' and is not useful. |
3200 | |
3201 | zip (Loc.U): |
5bf26616 |
3202 | This variable is used internally by Configure to determine the |
781b178c |
3203 | full pathname (if any) of the zip program. After Configure runs, |
3204 | the value is reset to a plain "zip" and is not useful. |
3205 | |
