3 This file is built by metaconfig.
5 This file contains a description of all the shell variables whose value is
6 determined by the Configure script. Variables intended for use in C
7 programs (e.g. I_UNISTD) are already described in config_h.SH. [`configpm'
8 generates pod documentation for Config.pm from this file--please try to keep
9 the formatting regular.]
12 This variable defines the extension used for ordinary library files.
13 For unix, it is '.a'. The '.' is included. Other possible
14 values include '.lib'.
17 This variable defines the extension used for executable files.
18 DJGPP, Cygwin and OS/2 use '.exe'. Stratus VOS uses '.pm'.
19 On operating systems which do not require a specific extension
20 for executable files, this variable is empty.
23 This variable defines the extension used for object files.
24 For unix, it is '.o'. The '.' is included. Other possible
25 values include '.obj'.
28 This variable is set to 'true' if AFS (Andrew File System) is used
29 on the system, 'false' otherwise. It is possible to override this
30 with a hint value or command line option, but you'd better know
34 This variable is by default set to '/afs'. In the unlikely case
35 this is not the correct root, it is possible to override this with
36 a hint value or command line option. This will be used in subsequent
37 tests for AFSness in the configure and test process.
39 alignbytes (alignbytes.U):
40 This variable holds the number of bytes required to align a
41 double-- or a long double when applicable. Usual values are
42 2, 4 and 8. The default is eight, for safety.
44 ansi2knr (ansi2knr.U):
45 This variable is set if the user needs to run ansi2knr.
46 Currently, this is not supported, so we just abort.
48 aphostname (d_gethname.U):
49 This variable contains the command which can be used to compute the
50 host name. The command is fully qualified by its absolute path, to make
51 it safe when used by a process with super-user privileges.
53 api_revision (patchlevel.U):
54 The three variables, api_revision, api_version, and
55 api_subversion, specify the version of the oldest perl binary
56 compatible with the present perl. In a full version string
57 such as '5.6.1', api_revision is the '5'.
58 Prior to 5.5.640, the format was a floating point number,
61 perl.c:incpush() and lib/lib.pm will automatically search in
62 $sitelib/.. for older directories back to the limit specified
63 by these api_ variables. This is only useful if you have a
64 perl library directory tree structured like the default one.
65 See INSTALL for how this works. The versioned site_perl
66 directory was introduced in 5.005, so that is the lowest
67 possible value. The version list appropriate for the current
68 system is determined in inc_version_list.U.
70 XXX To do: Since compatibility can depend on compile time
71 options (such as bincompat, longlong, etc.) it should
72 (perhaps) be set by Configure, but currently it isn't.
73 Currently, we read a hard-wired value from patchlevel.h.
74 Perhaps what we ought to do is take the hard-wired value from
75 patchlevel.h but then modify it if the current Configure
76 options warrant. patchlevel.h then would use an #ifdef guard.
78 api_subversion (patchlevel.U):
79 The three variables, api_revision, api_version, and
80 api_subversion, specify the version of the oldest perl binary
81 compatible with the present perl. In a full version string
82 such as '5.6.1', api_subversion is the '1'. See api_revision for
85 api_version (patchlevel.U):
86 The three variables, api_revision, api_version, and
87 api_subversion, specify the version of the oldest perl binary
88 compatible with the present perl. In a full version string
89 such as '5.6.1', api_version is the '6'. See api_revision for
90 full details. As a special case, 5.5.0 is rendered in the
91 old-style as 5.005. (In the 5.005_0x maintenance series,
92 this was the only versioned directory in $sitelib.)
94 api_versionstring (patchlevel.U):
95 This variable combines api_revision, api_version, and
96 api_subversion in a format such as 5.6.1 (or 5_6_1) suitable
97 for use as a directory name. This is filesystem dependent.
100 This variable is used internally by Configure to determine the
101 full pathname (if any) of the ar program. After Configure runs,
102 the value is reset to a plain "ar" and is not useful.
105 This variable holds the name of the directory in which the user wants
106 to put architecture-dependent public library files for $package.
107 It is most often a local directory such as /usr/local/lib.
108 Programs using this variable must be prepared to deal
109 with filename expansion.
111 archlibexp (archlib.U):
112 This variable is the same as the archlib variable, but is
113 filename expanded at configuration time, for convenient use.
115 archname (archname.U):
116 This variable is a short name to characterize the current
117 architecture. It is used mainly to construct the default archlib.
119 archname64 (use64bits.U):
120 This variable is used for the 64-bitness part of $archname.
123 This variable defines any additional objects that must be linked
124 in with the program on this architecture. On unix, it is usually
125 empty. It is typically used to include emulations of unix calls
126 or other facilities. For perl on OS/2, for example, this would
129 asctime_r_proto (d_asctime_r.U):
130 This variable encodes the prototype of asctime_r.

144 This variable is defined but not used by Configure.
145 The value is a plain '' and is not useful.
148 This variable holds the name of the directory in which the user wants
149 to put publicly executable images for the package in question. It
150 is most often a local directory such as /usr/local/bin. Programs using
151 this variable must be prepared to deal with ~name substitution.
154 This is the same as the bin variable, but is filename expanded at
155 configuration time, for use in your makefiles.
158 This variable is used internally by Configure to determine the
159 full pathname (if any) of the bison program. After Configure runs,
160 the value is reset to a plain "bison" and is not useful.

164 full pathname (if any) of the byacc program. After Configure runs,
165 the value is reset to a plain "byacc" and is not useful.
167 byteorder (byteorder.U):
168 This variable holds the byte order in a UV. In the following,
169 larger digits indicate more significance. The variable byteorder
170 is either 4321 on a big-endian machine, or 1234 on a little-endian,
171 or 87654321 on a Cray ... or 3412 with weird order !
174 This variable contains the \c string if that is what causes the echo
175 command to suppress newline. Otherwise it is null. Correct usage is
176 $echo $n "prompt for a question: $c".
178 castflags (d_castneg.U):
179 This variable contains a flag that precise difficulties the
180 compiler has casting odd floating values to unsigned long:

193 can resolve multiple global references that happen to have the same
194 name. Usual values are 'cc' and 'gcc'.
195 Fervent ANSI compilers may be called 'c89'. AIX has xlc.
197 cccdlflags (dlsrc.U):
198 This variable contains any special flags that might need to be
199 passed with 'cc -c' to compile modules to be used to create a shared
200 library that will be used for dynamic loading. For hpux, this
201 should be +z. It is up to the makefile to use it.
204 This variable contains any special flags that might need to be
205 passed to cc to link with a shared library for dynamic loading.
206 It is up to the makefile to use it. For sunos 4.1, it should

213 ccflags_uselargefiles (uselfs.U):
214 This variable contains the compiler flags needed by large file builds
215 and added to ccflags by hints files.
218 This can set either by hints files or by Configure. If using
219 gcc, this is gcc, and if not, usually equal to cc, unimpressive, no?
220 Some platforms, however, make good use of this by storing the
221 flavor of the C compiler being used here. For example if using
222 the Sun WorkShop suite, ccname will be 'workshop'.
224 ccsymbols (Cppsym.U):
225 The variable contains the symbols defined by the C compiler alone.
226 The symbols defined by cpp or by cc when it calls cpp are not in
227 this list, see cppsymbols and cppccsymbols.
228 The list is a space-separated list of symbol=value tokens.
230 ccversion (Checkcc.U):
231 This can set either by hints files or by Configure. If using
232 a (non-gcc) vendor cc, this variable may contain a version for

304 cppflags (ccflags.U):
305 This variable holds the flags that will be passed to the C pre-
306 processor. It is up to the Makefile to use it.
308 cpplast (cppstdin.U):
309 This variable has the same functionality as cppminus, only it applies
310 to cpprun and not cppstdin.
312 cppminus (cppstdin.U):
313 This variable contains the second part of the string which will invoke
314 the C preprocessor on the standard input and produce to standard
315 output. This variable will have the value "-" if cppstdin needs
316 a minus to specify standard input, otherwise the value is "".
319 This variable contains the command which will invoke a C preprocessor
320 on standard input and put the output to stdout. It is guaranteed not
321 to be a wrapper and may be a null string if no preprocessor can be
322 made directly available. This preprocessor might be different from the
323 one used by the C compiler. Don't forget to append cpplast after the
324 preprocessor options.
326 cppstdin (cppstdin.U):
327 This variable contains the command which will invoke the C

472 promotion rules. Also, the built-in function does not evaluate
473 the expression that was not chosen.
475 d_builtin_expect (d_builtin.U):

3277 This variable specifies the list of subdirectories in over
3278 which perl.c:incpush() and lib/lib.pm will automatically
3279 search when adding directories to @INC. The elements in
3280 the list are separated by spaces. This is only useful
3281 if you have a perl library directory tree structured like the
3282 default one. See INSTALL for how this works. The versioned
3283 site_perl directory was introduced in 5.005, so that is the
3284 lowest possible value.
3286 This list includes architecture-dependent directories back to
3287 version $api_versionstring (e.g. 5.5.640) and
3288 architecture-independent directories all the way back to
3291 inc_version_list_init (inc_version_list.U):

3307 that make install should copy the perl binary to, with all the
3308 run-time relocatable paths calculated from this at install time.
3309 When used, it is initialised to the original value of binexp, and
3310 then binexp is set to '.../', as the other binaries are found
3311 relative to the perl binary.

3320 the user is explicitely prompted for it. This variable should always
3321 be used in your makefiles for maximum portability.
3323 installhtml1dir (html1dir.U):
3324 This variable is really the same as html1direxp, unless you are

3340 This variable is really the same as man3direxp, unless you are using
3341 AFS in which case it points to the read/write location whereas
3342 man3direxp only points to the read-only access location. For extra
3343 portability, you should only use this variable within your makefiles.
3345 installprefix (installprefix.U):
3346 This variable holds the name of the directory below which
3347 "make install" will install the package. For most users, this
3348 is the same as prefix. However, it is useful for
3349 installing the software into a different (usually temporary)
3350 location after which it can be bundled up and moved somehow
3351 to the final location specified by prefix.

3373 This variable is usually the same as sitebinexp, unless you are on
3374 a system running AFS, in which case they may differ slightly. You
3375 should always use this variable within your makefiles for portability.
3377 installsitehtml1dir (sitehtml1dir.U):
3378 This variable is really the same as sitehtml1direxp, unless you are using
3379 AFS in which case it points to the read/write location whereas

3381 portability, you should only use this variable within your makefiles.
3383 installsitehtml3dir (sitehtml3dir.U):
3384 This variable is really the same as sitehtml3direxp, unless you are using
3385 AFS in which case it points to the read/write location whereas

3396 AFS in which case it points to the read/write location whereas
3397 man1direxp only points to the read-only access location. For extra
3398 portability, you should only use this variable within your makefiles.

3402 AFS in which case it points to the read/write location whereas
3403 man3direxp only points to the read-only access location. For extra
3404 portability, you should only use this variable within your makefiles.
3406 installsitescript (sitescript.U):
3407 This variable is usually the same as sitescriptexp, unless you are on
3408 a system running AFS, in which case they may differ slightly. You
3409 should always use this variable within your makefiles for portability.
3411 installstyle (installstyle.U):
3412 This variable describes the "style" of the perl installation.
3413 This is intended to be useful for tools that need to
3414 manipulate entire perl distributions. Perl itself doesn't use
3415 this to find its libraries -- the library directories are
3416 stored directly in Config.pm. Currently, there are only two
3417 styles: "lib" and "lib/perl5". The default library locations
3418 (e.g. privlib, sitelib) are either $prefix/lib or
3419 $prefix/lib/perl5. The former is useful if $prefix is a
3420 directory dedicated to perl (e.g. /opt/perl), while the latter
3421 is useful if $prefix is shared by many packages, e.g. if
3424 Unfortunately, while this "style" variable is used to set
3425 defaults for all three directory hierarchies (core, vendor, and
3426 site), there is no guarantee that the same style is actually
3427 appropriate for all those directories. For example, $prefix
3428 might be /opt/perl, but $siteprefix might be /usr/local.
3429 (Perhaps, in retrospect, the "lib" style should never have been
3430 supported, but it did seem like a nice idea at the time.)
3432 The situation is even less clear for tools such as MakeMaker
3433 that can be used to install additional modules into
3434 non-standard places. For example, if a user intends to install
3435 a module into a private directory (perhaps by setting PREFIX on
3436 the Makefile.PL command line), then there is no reason to
3437 assume that the Configure-time $installstyle setting will be
3438 relevant for that PREFIX.
3440 This may later be extended to include other information, so
3441 be careful with pattern-matching on the results.
3443 For compatibility with perl5.005 and earlier, the default
3444 setting is based on whether or not $prefix contains the string
3447 installusrbinperl (instubperl.U):

3449 /usr/bin/perl in addition to
3452 installvendorarch (vendorarch.U):
3453 This variable is really the same as vendorarchexp but may differ on
3454 those systems using AFS. For extra portability, only this variable
3455 should be used in makefiles.
3457 installvendorbin (vendorbin.U):
3458 This variable is really the same as vendorbinexp but may differ on

3480 should be used in makefiles.
3482 installvendorman3dir (vendorman3dir.U):
3483 This variable is really the same as vendorman3direxp but may differ on

3520 This variable indicates the program to be used to link
3521 libraries for dynamic loading. On some systems, it is 'ld'.
3522 On ELF systems, it should be $cc. Mostly, we'll try to respect
3523 the hint file setting.
3525 lddlflags (dlsrc.U):
3526 This variable contains any special flags that might need to be
3527 passed to $ld to create a shared library suitable for dynamic
3528 loading. It is up to the makefile to use it. For hpux, it
3529 should be '-b'. For sunos 4.1, it is empty.
3531 ldflags (ccflags.U):
3532 This variable contains any additional C loader flags desired by
3533 the user. It is up to the Makefile to use this.
3535 ldflags_uselargefiles (uselfs.U):

3537 and added to ldflags by hints files.
3539 ldlibpthname (libperl.U):

3541 search path, often LD_LIBRARY_PATH. To get an empty
3542 string, the hints file must set this to 'none'.
3545 This variable is used internally by Configure to determine the
3546 full pathname (if any) of the less program. After Configure runs,
3547 the value is reset to a plain "less" and is not useful.
3550 This is an old synonym for _a.
3553 This variable contains the location of the C library.
3555 libperl (libperl.U):
3556 The perl executable is obtained by linking perlmain.c with
3557 libperl, any static extensions (usually just DynaLoader),
3558 and any other libraries needed on this system. libperl
3559 is usually libperl.a, but can also be libperl.so.xxx if
3560 the user wishes to build a perl executable with a shared

3592 This variable contains the libraries needed by large file builds
3593 and added to ldflags by hints files. It is a space separated list
3594 of the library names without the "lib" prefix or any suffix, just
3598 This variable is defined but not used by Configure.
3599 The value is a plain '' and is not useful.
3602 This variable is defined but not used by Configure.
3603 The value is a plain '' and is not useful.
3605 lkflags (ccflags.U):
3606 This variable contains any additional C partial linker flags desired by
3607 the user. It is up to the Makefile to use this.
3610 This variable is used internally by Configure to determine the
3611 full pathname (if any) of the ln program. After Configure runs,
3612 the value is reset to a plain "ln" and is not useful.
3615 This variable holds the name of the command to make
3616 symbolic links (if they are supported). It can be used
3617 in the Makefile. It is either 'ln -s' or 'ln'
3619 localtime_r_proto (d_localtime_r.U):
3620 This variable encodes the prototype of localtime_r.
3621 It is zero if d_localtime_r is undef, and one of the
3622 REENTRANT_PROTO_T_ABC macros of reentr.h if d_localtime_r
3625 locincpth (ccflags.U):
3626 This variable contains a list of additional directories to be
3627 searched by the compiler. The appropriate '-I' directives will
3628 be added to ccflags. This is intended to simplify setting
3629 local directories from the Configure command line.
3630 It's not much, but it parallels the loclibpth stuff in libpth.U.
3632 loclibpth (libpth.U):
3633 This variable holds the paths (space-separated) used to find local
3634 libraries. It is prepended to libpth, and is intended to be easily
3635 set from the command line.

3639 indicates to the C program how many bytes there are in a long double,
3640 if this system supports long doubles.
3642 longlongsize (d_longlong.U):
3643 This variable contains the value of the LONGLONGSIZE symbol, which
3644 indicates to the C program how many bytes there are in a long long,
3645 if this system supports long long.
3647 longsize (intsize.U):
3648 This variable contains the value of the LONGSIZE symbol, which
3649 indicates to the C program how many bytes there are in a long.
3652 This variable is defined but not used by Configure.
3653 The value is a plain '' and is not useful.
3656 This variable is defined but not used by Configure.
3657 The value is a plain '' and is not useful.
3660 This variable is used internally by Configure to determine the
3661 full pathname (if any) of the ls program. After Configure runs,
3662 the value is reset to a plain "ls" and is not useful.
3664 lseeksize (lseektype.U):
3665 This variable defines lseektype to be something like off_t, long,
3666 or whatever type is used to declare lseek offset's type in the
3667 kernel (which also appears to be lseek's return type).
3669 lseektype (lseektype.U):
3670 This variable defines lseektype to be something like off_t, long,
3671 or whatever type is used to declare lseek offset's type in the
3672 kernel (which also appears to be lseek's return type).
3675 This variable indicates that the Misc Attribute Definition code is to
3679 If the Misc Attribute Decoration is to be compiled, this variable is
3680 set to the name of the extra header files to be used, else it is ''
3683 If the Misc Attribute Decoration is to be compiled, this variable is
3684 set to the name of the extra object files to be used, else it is ''
3687 If the Misc Attribute Decoration is to be compiled, this variable is
3688 set to the name of the extra C source files to be used, else it is ''

3695 This variable is defined but not used by Configure.
3696 The value is a plain '' and is not useful.
3699 This variable is used internally by Configure to determine the
3700 full pathname (if any) of the make program. After Configure runs,
3701 the value is reset to a plain "make" and is not useful.

3704 Some versions of 'make' set the variable MAKE. Others do not.
3705 This variable contains the string to be included in Makefile.SH
3706 so that MAKE is set if needed, and not if not needed.
3707 Possible values are:
3709 make_set_make='#' # If your make program handles this for you,
3711 make_set_make="MAKE=$make" # if it doesn't.
3713 This uses a comment character so that we can distinguish a
3714 'set' value (from a previous config.sh or Configure '-D' option)
3715 from an uncomputed value.
3717 mallocobj (mallocsrc.U):
3718 This variable contains the name of the malloc.o that this package
3719 generates, if that malloc.o is preferred over the system malloc.
3720 Otherwise the value is null. This variable is intended for generating
3721 Makefiles. See mallocsrc.
3723 mallocsrc (mallocsrc.U):
3724 This variable contains the name of the malloc.c that comes with
3725 the package, if that malloc.c is preferred over the system malloc.
3726 Otherwise the value is null. This variable is intended for generating
3729 malloctype (mallocsrc.U):
3730 This variable contains the kind of ptr returned by malloc and realloc.
3732 man1dir (man1dir.U):
3733 This variable contains the name of the directory in which manual
3734 source pages are to be put. It is the responsibility of the
3735 Makefile.SH to get the value of this into the proper command.
3736 You must be prepared to do the ~name expansion yourself.
3738 man1direxp (man1dir.U):
3739 This variable is the same as the man1dir variable, but is filename
3740 expanded at configuration time, for convenient use in makefiles.
3742 man1ext (man1dir.U):
3743 This variable contains the extension that the manual page should
3744 have: one of 'n', 'l', or '1'. The Makefile must supply the '.'.
3747 man3dir (man3dir.U):
3748 This variable contains the name of the directory in which manual
3749 source pages are to be put. It is the responsibility of the
3750 Makefile.SH to get the value of this into the proper command.
3751 You must be prepared to do the ~name expansion yourself.
3753 man3direxp (man3dir.U):
3754 This variable is the same as the man3dir variable, but is filename
3755 expanded at configuration time, for convenient use in makefiles.
3757 man3ext (man3dir.U):
3758 This variable contains the extension that the manual page should
3759 have: one of 'n', 'l', or '3'. The Makefile must supply the '.'.
3762 mips_type (usrinc.U):
3763 This variable holds the environment type for the mips system.
3764 Possible values are "BSD 4.3" and "System V".
3766 mistrustnm (Csym.U):
3767 This variable can be used to establish a fallthrough for the cases
3768 where nm fails to find a symbol. If usenm is false or usenm is true
3769 and mistrustnm is false, this variable has no effect. If usenm is true
3770 and mistrustnm is "compile", a test program will be compiled to try to
3771 find any symbol that can't be located via nm lookup. If mistrustnm is
3772 "run", the test program will be run as well as being compiled.
3775 This variable is used internally by Configure to determine the
3776 full pathname (if any) of the mkdir program. After Configure runs,
3777 the value is reset to a plain "mkdir" and is not useful.
3779 mmaptype (d_mmap.U):
3780 This symbol contains the type of pointer returned by mmap()
3781 (and simultaneously the type of the first argument).
3782 It can be 'void *' or 'caddr_t'.
3784 modetype (modetype.U):
3785 This variable defines modetype to be something like mode_t,
3786 int, unsigned short, or whatever type is used to declare file
3787 modes for system calls.
3790 This variable is used internally by Configure to determine the
3791 full pathname (if any) of the more program. After Configure runs,
3792 the value is reset to a plain "more" and is not useful.
3794 multiarch (multiarch.U):
3795 This variable conditionally defines the MULTIARCH symbol
3796 which signifies the presence of multiplatform files.
3797 This is normally set by hints files.
3800 This variable is defined but not used by Configure.
3801 The value is a plain '' and is not useful.
3803 myarchname (archname.U):
3804 This variable holds the architecture name computed by Configure in
3805 a previous run. It is not intended to be perused by any user and
3806 should never be set in a hint file.
3808 mydomain (myhostname.U):
3809 This variable contains the eventual value of the MYDOMAIN symbol,
3810 which is the domain of the host the program is going to run on.
3811 The domain must be appended to myhostname to form a complete host name.
3812 The dot comes with mydomain, and need not be supplied by the program.
3814 myhostname (myhostname.U):
3815 This variable contains the eventual value of the MYHOSTNAME symbol,
3816 which is the name of the host the program is going to run on.
3817 The domain is not kept with hostname, but must be gotten from mydomain.
3818 The dot comes with mydomain, and need not be supplied by the program.
3820 myuname (Oldconfig.U):
3821 The output of 'uname -a' if available, otherwise the hostname. On Xenix,
3822 pseudo variables assignments in the output are stripped, thank you. The
3823 whole thing is then lower-cased.
3826 This variable contains the '-n' flag if that is what causes the echo
3827 command to suppress newline. Otherwise it is null. Correct usage is
3828 $echo $n "prompt for a question: $c".
3830 need_va_copy (need_va_copy.U):
3831 This symbol, if defined, indicates that the system stores
3832 the variable argument list datatype, va_list, in a format
3833 that cannot be copied by simple assignment, so that some
3834 other means must be used when copying is required.
3835 As such systems vary in their provision (or non-provision)
3836 of copying mechanisms, handy.h defines a platform-
3837 independent macro, Perl_va_copy(src, dst), to do the job.
3839 netdb_hlen_type (netdbtype.U):
3840 This variable holds the type used for the 2nd argument to
3841 gethostbyaddr(). Usually, this is int or size_t or unsigned.

3844 netdb_host_type (netdbtype.U):
3845 This variable holds the type used for the 1st argument to
3846 gethostbyaddr(). Usually, this is char * or void *, possibly
3847 with or without a const prefix.

3850 netdb_name_type (netdbtype.U):
3851 This variable holds the type used for the argument to
3852 gethostbyname(). Usually, this is char * or const char *.

3856 This variable holds the type used for the 1st argument to
3857 getnetbyaddr(). Usually, this is int or long.
3858 This is only useful if you have getnetbyaddr(), naturally.
3861 This variable is used internally by Configure to determine the
3862 full pathname (if any) of the nm program. After Configure runs,
3863 the value is reset to a plain "nm" and is not useful.
3866 This variable holds the options that may be necessary for nm.
3868 nm_so_opt (usenm.U):
3869 This variable holds the options that may be necessary for nm
3870 to work on a shared library but that can not be used on an
3871 archive library. Currently, this is only used by Linux, where
3872 nm --dynamic is *required* to get symbols from an ELF library which
3873 has been stripped, but nm --dynamic is *fatal* on an archive library.
3874 Maybe Linux should just always set usenm=false.
3876 nonxs_ext (Extensions.U):
3877 This variable holds a list of all non-xs extensions included
3878 in the package. All of them will be built.
3881 This variable is used internally by Configure to determine the

3896 a Perl NV using %e-ish floating point format.
3898 nvEUformat (perlxvf.U):
3899 This variable contains the format string used for printing
3900 a Perl NV using %E-ish floating point format.
3902 nvfformat (perlxvf.U):
3903 This variable confains the format string used for printing
3904 a Perl NV using %f-ish floating point format.
3906 nvFUformat (perlxvf.U):
3907 This variable confains the format string used for printing
3908 a Perl NV using %F-ish floating point format.
3910 nvgformat (perlxvf.U):
3911 This variable contains the format string used for printing
3912 a Perl NV using %g-ish floating point format.
3914 nvGUformat (perlxvf.U):

3919 This variable is the size of an NV in bytes.
3922 This variable contains the C type used for Perl's NV.
3924 o_nonblock (nblock_io.U):
3925 This variable bears the symbol value to be used during open() or fcntl()
3926 to turn on non-blocking I/O for a file descriptor. If you wish to switch
3927 between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead,
3928 but that is only supported by some devices.
3931 This is an old synonym for _o.
3933 old_pthread_create_joinable (d_pthrattrj.U):
3934 This variable defines the constant to use for creating joinable
3935 (aka undetached) pthreads. Unused if pthread.h defines
3936 PTHREAD_CREATE_JOINABLE. If used, possible values are
3937 PTHREAD_CREATE_UNDETACHED and __UNDETACHED.
3939 optimize (ccflags.U):
3940 This variable contains any optimizer/debugger flag that should be used.
3941 It is up to the Makefile to use it.
3943 orderlib (orderlib.U):
3944 This variable is "true" if the components of libraries must be ordered
3945 (with `lorder $* | tsort`) before placing them in an archive. Set to
3946 "false" if ranlib or ar can generate random libraries.
3948 osname (Oldconfig.U):
3949 This variable contains the operating system name (e.g. sunos,
3950 solaris, hpux, etc.). It can be useful later on for setting
3951 defaults. Any spaces are replaced with underscores. It is set
3952 to a null string if we can't figure it out.
3954 osvers (Oldconfig.U):
3955 This variable contains the operating system version (e.g.
3956 4.1.3, 5.2, etc.). It is primarily used for helping select
3957 an appropriate hints file, but might be useful elsewhere for
3958 setting defaults. It is set to '' if we can't figure it out.
3959 We try to be flexible about how much of the version number
3960 to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the
3961 same for this package, hints files might just be os_4.0 or
3962 os_4.1, etc., not keeping separate files for each little release.
3964 otherlibdirs (otherlibdirs.U):
3965 This variable contains a colon-separated set of paths for the perl
3966 binary to search for additional library files or modules.
3967 These directories will be tacked to the end of @INC.
3968 Perl will automatically search below each path for version-
3969 and architecture-specific directories. See inc_version_list
3971 A value of ' ' means 'none' and is used to preserve this value
3972 for the next run through Configure.
3974 package (package.U):
3975 This variable contains the name of the package being constructed.
3976 It is primarily intended for the use of later Configure units.
3979 This variable contains the name of the preferred pager on the system.
3980 Usual values are (the full pathnames of) more, less, pg, or cat.
3983 This variable contains a command that produces the text of the
3984 /etc/passwd file. This is normally "cat /etc/passwd", but can be
3985 "ypcat passwd" when NIS is used.
3986 On some systems, such as os390, there may be no equivalent
3987 command, in which case this variable is unset.
3989 patchlevel (patchlevel.U):
3990 The patchlevel level of this package.
3991 The value of patchlevel comes from the patchlevel.h file.
3992 In a version number such as 5.6.1, this is the "6".
3993 In patchlevel.h, this is referred to as "PERL_VERSION".
3996 This is an old synonym for p_ in Head.U, the character
3997 used to separate elements in the command shell search PATH.
4000 This variable is defined but not used by Configure.
4001 The value is a plain '' and is not useful.
4004 This variable contains the full path (if any) to a previously
4005 installed perl5.005 or later suitable for running the script
4006 to determine inc_version_list.
4008 PERL_API_REVISION (patchlevel.h):
4009 This number describes the earliest compatible PERL_REVISION of
4010 Perl ("compatibility" here being defined as sufficient binary/API
4011 compatibility to run XS code built with the older version).
4012 Normally this does not change across maintenance releases.
4013 Please read the comment in patchlevel.h.
4015 PERL_API_SUBVERSION (patchlevel.h):
4016 This number describes the earliest compatible PERL_SUBVERSION of
4017 Perl ("compatibility" here being defined as sufficient binary/API
4018 compatibility to run XS code built with the older version).
4019 Normally this does not change across maintenance releases.
4020 Please read the comment in patchlevel.h.
4022 PERL_API_VERSION (patchlevel.h):
4023 This number describes the earliest compatible PERL_VERSION of
4024 Perl ("compatibility" here being defined as sufficient binary/API
4025 compatibility to run XS code built with the older version).
4026 Normally this does not change across maintenance releases.
4027 Please read the comment in patchlevel.h.
4029 PERL_CONFIG_SH (Oldsyms.U):
4030 This is set to 'true' in config.sh so that a shell script
4031 sourcing config.sh can tell if it has been sourced already.
4033 PERL_PATCHLEVEL (Oldsyms.U):
4034 This symbol reflects the patchlevel, if available. Will usually
4035 come from the .patch file, which is available when the perl

4069 which contains the name of the perl interpreter to be used in
4070 shell scripts and in the "eval 'exec'" idiom. This variable is
4071 not necessarily the pathname of the file containing the perl
4072 interpreter; you must append the executable extension (_exe) if
4073 it is not already present. Note that Perl code that runs during
4074 the Perl build process cannot reference this variable, as Perl
4075 may not have been installed, or even if installed, may be a
4076 different version of Perl.

4170 random libraries or if random libraries are not supported
4172 rd_nodata (nblock_io.U):
4173 This variable holds the return code from read() when no data is
4174 present. It should be -1, but some systems return 0 when O_NDELAY is
4175 used, which is a shame because you cannot make the difference between
4176 no data and an EOF.. Sigh!

4734 This is unique to perl.
4737 This variable holds the place where the manual is located on this
4738 system. It is not the place where the user wants to put his manual
4739 pages. Rather it is the place where Configure may look to find manual

4869 threading implementation. Only valid up to 5.8.x.
4871 use64bitall (use64bits.U):
4872 This variable conditionally defines the USE_64_BIT_ALL symbol,
4873 and indicates that 64-bit integer types should be used
4874 when available. The maximal possible
4875 64-bitness is employed: LP64 or ILP64, meaning that you will
4876 be able to use more than 2 gigabytes of memory. This mode is
4877 even more binary incompatible than USE_64_BIT_INT. You may not
4878 be able to run the resulting executable in a 32-bit CPU at all or
4879 you may need at least to reboot your OS to 64-bit mode.
4881 use64bitint (use64bits.U):
4882 This variable conditionally defines the USE_64_BIT_INT symbol,
4883 and indicates that 64-bit integer types should be used
4884 when available. The minimal possible 64-bitness
4885 is employed, just enough to get 64-bit integers into Perl.
4886 This may mean using for example "long longs", while your memory
4887 may still be limited to 2 gigabytes.

4890 This variable conditionally defines the USE_CROSS_COMPILE symbol,
4891 and indicates that Perl has been cross-compiled.

4925 This variable conditionally defines the USE_MORE_BITS symbol,
4926 and indicates that explicit 64-bit interfaces and long doubles
4927 should be used when available.

4931 and indicates that Perl should be built to use multiplicity.
4933 usemymalloc (mallocsrc.U):
4934 This variable contains y if the malloc that comes with this package
4935 is desired over the system's version of malloc. People often include
4936 special versions of malloc for effiency, but such versions are often
4937 less portable. See also mallocsrc and mallocobj.
4938 If this is 'y', then -lmalloc is removed from $libs.
4941 This variable contains 'true' or 'false' depending whether the
4942 nm extraction is wanted or not.
4944 useopcode (Extensions.U):
4945 This variable holds either 'true' or 'false' to indicate
4946 whether the Opcode extension should be used. The sole
4947 use for this currently is to allow an easy mechanism
4948 for users to skip the Opcode extension from the Configure
4951 useperlio (useperlio.U):
4952 This variable conditionally defines the USE_PERLIO symbol,
4953 and indicates that the PerlIO abstraction should be
4956 useposix (Extensions.U):
4957 This variable holds either 'true' or 'false' to indicate
4958 whether the POSIX extension should be used. The sole
4959 use for this currently is to allow an easy mechanism
4960 for hints files to indicate that POSIX will not compile
4961 on a particular system.
4963 usereentrant (usethreads.U):
4964 This variable conditionally defines the USE_REENTRANT_API symbol,
4965 which indicates that the thread code may try to use the various
4966 _r versions of library functions. This is only potentially
4967 meaningful if usethreads is set and is very experimental, it is
4968 not even prompted for.
4970 userelocatableinc (bin.U):
4971 This variable is set to true to indicate that perl should relocate
4972 @INC entries at runtime based on the path to the perl binary.
4973 Any @INC paths starting ".../" are relocated relative to the directory
4974 containing the perl binary, and a logical cleanup of the path is then
4975 made around the join point (removing "dir/../" pairs)
4978 This variable is set to true when the user agrees to use sfio.
4979 It is set to false when sfio is not available or when the user
4980 explicitely requests not to use sfio. It is here primarily so
4981 that command-line settings can override the auto-detection of
4982 d_sfio without running into a "WHOA THERE".
4984 useshrplib (libperl.U):
4985 This variable is set to 'true' if the user wishes
4986 to build a shared libperl, and 'false' otherwise.
4988 usesitecustomize (d_sitecustomize.U):
4989 This variable is set to true when the user requires a mechanism that
4990 allows the sysadmin to add entries to @INC at runtime. This variable
4991 being set, makes perl run '$sitelib/sitecustomize.pl' at startup.
4993 usesocks (usesocks.U):
4994 This variable conditionally defines the USE_SOCKS symbol,
4995 and indicates that Perl should be built to use SOCKS.

5007 It is set to false when no vfork is available or when the user
5008 explicitely requests not to use vfork.
5011 This variable holds the path of the include files, which is
5012 usually /usr/include. It is mainly used by other Configure units.
5015 This variable is defined but not used by Configure.
5016 The value is a plain '' and is not useful.

5162 This is suitable for use as a directory name, and hence is
5163 filesystem dependent.
5165 version_patchlevel_string (patchlevel.U):
5166 This is a string combining version, subversion and
