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.
131 It is zero if d_asctime_r is undef, and one of the
132 REENTRANT_PROTO_T_ABC macros of reentr.h if d_asctime_r

145 The value is the empty string 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 variable saves the result from configure if generated binaries
155 are in ELF format. Only set to defined when the test has actually
156 been performed, and the result was positive.
159 This is the same as the bin variable, but is filename expanded at
160 configuration time, for use in your makefiles.
163 This variable is used internally by Configure to determine the
164 full pathname (if any) of the bison program. After Configure runs,
165 the value is reset to a plain "bison" and is not useful.
168 This variable is used internally by Configure to determine the
169 full pathname (if any) of the byacc program. After Configure runs,
170 the value is reset to a plain "byacc" and is not useful.
172 byteorder (byteorder.U):
173 This variable holds the byte order in a UV. In the following,
174 larger digits indicate more significance. The variable byteorder
175 is either 4321 on a big-endian machine, or 1234 on a little-endian,
176 or 87654321 on a Cray ... or 3412 with weird order !
179 This variable contains the \c string if that is what causes the echo
180 command to suppress newline. Otherwise it is null. Correct usage is
181 $echo $n "prompt for a question: $c".
183 castflags (d_castneg.U):
184 This variable contains a flag that precise difficulties the
185 compiler has casting odd floating values to unsigned long:

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

216 the user. It is up to the Makefile to use this.
218 ccflags_uselargefiles (uselfs.U):
219 This variable contains the compiler flags needed by large file builds
220 and added to ccflags by hints files.
223 This can set either by hints files or by Configure. If using
224 gcc, this is gcc, and if not, usually equal to cc, unimpressive, no?
225 Some platforms, however, make good use of this by storing the
226 flavor of the C compiler being used here. For example if using
227 the Sun WorkShop suite, ccname will be 'workshop'.
229 ccsymbols (Cppsym.U):
230 The variable contains the symbols defined by the C compiler alone.
231 The symbols defined by cpp or by cc when it calls cpp are not in
232 this list, see cppsymbols and cppccsymbols.
233 The list is a space-separated list of symbol=value tokens.
235 ccversion (Checkcc.U):
236 This can set either by hints files or by Configure. If using
237 a (non-gcc) vendor cc, this variable may contain a version for
241 Login name of the person who ran the Configure script and answered the
242 questions. This is used to tag both config.sh and config_h.SH.
244 cf_email (cf_email.U):
245 Electronic mail address of the person who ran Configure. This can be
246 used by units that require the user's e-mail, like MailList.U.

282 it is a grep followed by a cat followed by a test. This variable
283 is primarily for the use of other Configure units.
286 This variable is used internally by Configure to determine the
287 full pathname (if any) of the cp program. After Configure runs,

311 processor. It is up to the Makefile to use it.
313 cpplast (cppstdin.U):
314 This variable has the same functionality as cppminus, only it applies
315 to cpprun and not cppstdin.
317 cppminus (cppstdin.U):
318 This variable contains the second part of the string which will invoke
319 the C preprocessor on the standard input and produce to standard
320 output. This variable will have the value "-" if cppstdin needs
321 a minus to specify standard input, otherwise the value is "".
324 This variable contains the command which will invoke a C preprocessor
325 on standard input and put the output to stdout. It is guaranteed not
326 to be a wrapper and may be a null string if no preprocessor can be
327 made directly available. This preprocessor might be different from the
328 one used by the C compiler. Don't forget to append cpplast after the
329 preprocessor options.
331 cppstdin (cppstdin.U):
332 This variable contains the command which will invoke the C
333 preprocessor on standard input and put the output to stdout.
334 It is primarily used by other Configure units that ask about
335 preprocessor symbols.

3442 This variable describes the "style" of the perl installation.
3443 This is intended to be useful for tools that need to
3444 manipulate entire perl distributions. Perl itself doesn't use
3445 this to find its libraries -- the library directories are
3446 stored directly in Config.pm. Currently, there are only two
3447 styles: "lib" and "lib/perl5". The default library locations
3448 (e.g. privlib, sitelib) are either $prefix/lib or
3449 $prefix/lib/perl5. The former is useful if $prefix is a
3450 directory dedicated to perl (e.g. /opt/perl), while the latter
3451 is useful if $prefix is shared by many packages, e.g. if
3454 Unfortunately, while this "style" variable is used to set
3455 defaults for all three directory hierarchies (core, vendor, and
3456 site), there is no guarantee that the same style is actually
3457 appropriate for all those directories. For example, $prefix
3458 might be /opt/perl, but $siteprefix might be /usr/local.
3459 (Perhaps, in retrospect, the "lib" style should never have been
3460 supported, but it did seem like a nice idea at the time.)
3462 The situation is even less clear for tools such as MakeMaker
3463 that can be used to install additional modules into
3464 non-standard places. For example, if a user intends to install
3465 a module into a private directory (perhaps by setting PREFIX on
3466 the Makefile.PL command line), then there is no reason to
3467 assume that the Configure-time $installstyle setting will be
3468 relevant for that PREFIX.
3470 This may later be extended to include other information, so
3471 be careful with pattern-matching on the results.
3473 For compatibility with perl5.005 and earlier, the default
3474 setting is based on whether or not $prefix contains the string
3477 installusrbinperl (instubperl.U):
3478 This variable tells whether Perl should be installed also as
3479 /usr/bin/perl in addition to
3482 installvendorarch (vendorarch.U):
3483 This variable is really the same as vendorarchexp but may differ on
3484 those systems using AFS. For extra portability, only this variable
3485 should be used in makefiles.
3487 installvendorbin (vendorbin.U):
3488 This variable is really the same as vendorbinexp but may differ on
3489 those systems using AFS. For extra portability, only this variable
3490 should be used in makefiles.

3500 should be used in makefiles.
3502 installvendorlib (vendorlib.U):
3503 This variable is really the same as vendorlibexp but may differ on
3504 those systems using AFS. For extra portability, only this variable
3505 should be used in makefiles.
3507 installvendorman1dir (vendorman1dir.U):
3508 This variable is really the same as vendorman1direxp but may differ on
3509 those systems using AFS. For extra portability, only this variable
3510 should be used in makefiles.
3512 installvendorman3dir (vendorman3dir.U):
3513 This variable is really the same as vendorman3direxp but may differ on

3541 known_extensions (Extensions.U):
3542 This variable holds a list of all XS extensions included in
3546 This variable is defined but not used by Configure.
3547 The value is the empty string and is not useful.
3550 This variable indicates the program to be used to link
3551 libraries for dynamic loading. On some systems, it is 'ld'.
3552 On ELF systems, it should be $cc. Mostly, we'll try to respect
3553 the hint file setting.
3555 lddlflags (dlsrc.U):
3556 This variable contains any special flags that might need to be
3557 passed to $ld to create a shared library suitable for dynamic
3558 loading. It is up to the makefile to use it. For hpux, it
3559 should be '-b'. For sunos 4.1, it is empty.
3561 ldflags (ccflags.U):
3562 This variable contains any additional C loader flags desired by
3563 the user. It is up to the Makefile to use this.
3565 ldflags_uselargefiles (uselfs.U):
3566 This variable contains the loader flags needed by large file builds
3567 and added to ldflags by hints files.
3569 ldlibpthname (libperl.U):
3570 This variable holds the name of the shared library
3571 search path, often LD_LIBRARY_PATH. To get an empty
3572 string, the hints file must set this to 'none'.
3575 This variable is used internally by Configure to determine the
3576 full pathname (if any) of the less program. After Configure runs,
3577 the value is reset to a plain "less" and is not useful.
3580 This is an old synonym for _a.
3583 This variable contains the location of the C library.
3585 libperl (libperl.U):
3586 The perl executable is obtained by linking perlmain.c with
3587 libperl, any static extensions (usually just DynaLoader),
3588 and any other libraries needed on this system. libperl
3589 is usually libperl.a, but can also be libperl.so.xxx if
3590 the user wishes to build a perl executable with a shared
3594 This variable holds the general path (space-separated) used to find
3595 libraries. It is intended to be used by other units.
3598 This variable holds the additional libraries we want to use.
3599 It is up to the Makefile to deal with it. The list can be empty.
3602 This variable holds the directory names aka dirnames of the libraries
3603 we found and accepted, duplicates are removed.

3619 ahead of ucb or bsd libraries for SVR4.
3621 libswanted_uselargefiles (uselfs.U):
3622 This variable contains the libraries needed by large file builds
3623 and added to ldflags by hints files. It is a space separated list
3624 of the library names without the "lib" prefix or any suffix, just
3628 This variable is defined but not used by Configure.
3629 The value is the empty string and is not useful.
3632 This variable is defined but not used by Configure.
3633 The value is the empty string and is not useful.
3635 lkflags (ccflags.U):
3636 This variable contains any additional C partial linker flags desired by
3637 the user. It is up to the Makefile to use this.
3640 This variable is used internally by Configure to determine the
3641 full pathname (if any) of the ln program. After Configure runs,
3642 the value is reset to a plain "ln" and is not useful.
3645 This variable holds the name of the command to make
3646 symbolic links (if they are supported). It can be used
3647 in the Makefile. It is either 'ln -s' or 'ln'
3649 localtime_r_proto (d_localtime_r.U):
3650 This variable encodes the prototype of localtime_r.
3651 It is zero if d_localtime_r is undef, and one of the
3652 REENTRANT_PROTO_T_ABC macros of reentr.h if d_localtime_r
3655 locincpth (ccflags.U):
3656 This variable contains a list of additional directories to be
3657 searched by the compiler. The appropriate '-I' directives will
3658 be added to ccflags. This is intended to simplify setting
3659 local directories from the Configure command line.
3660 It's not much, but it parallels the loclibpth stuff in libpth.U.
3662 loclibpth (libpth.U):
3663 This variable holds the paths (space-separated) used to find local
3664 libraries. It is prepended to libpth, and is intended to be easily
3665 set from the command line.
3667 longdblsize (d_longdbl.U):
3668 This variable contains the value of the LONG_DOUBLESIZE symbol, which
3669 indicates to the C program how many bytes there are in a long double,
3670 if this system supports long doubles.
3672 longlongsize (d_longlong.U):
3673 This variable contains the value of the LONGLONGSIZE symbol, which
3674 indicates to the C program how many bytes there are in a long long,
3675 if this system supports long long.
3677 longsize (intsize.U):
3678 This variable contains the value of the LONGSIZE symbol, which
3679 indicates to the C program how many bytes there are in a long.
3682 This variable is defined but not used by Configure.
3683 The value is the empty string and is not useful.
3686 This variable is defined but not used by Configure.
3687 The value is the empty string and is not useful.
3690 This variable is used internally by Configure to determine the
3691 full pathname (if any) of the ls program. After Configure runs,
3692 the value is reset to a plain "ls" and is not useful.
3694 lseeksize (lseektype.U):
3695 This variable defines lseektype to be something like off_t, long,
3696 or whatever type is used to declare lseek offset's type in the
3697 kernel (which also appears to be lseek's return type).
3699 lseektype (lseektype.U):
3700 This variable defines lseektype to be something like off_t, long,
3701 or whatever type is used to declare lseek offset's type in the
3702 kernel (which also appears to be lseek's return type).
3705 This variable indicates that the Misc Attribute Definition code is to
3709 If the Misc Attribute Decoration is to be compiled, this variable is
3710 set to the name of the extra header files to be used, else it is ''
3713 If the Misc Attribute Decoration is to be compiled, this variable is
3714 set to the name of the extra object files to be used, else it is ''
3717 If the Misc Attribute Decoration is to be compiled, this variable is
3718 set to the name of the extra C source files to be used, else it is ''
3721 This variable is defined but not used by Configure.
3722 The value is the empty string and is not useful.
3725 This variable is defined but not used by Configure.
3726 The value is the empty string and is not useful.
3729 This variable is used internally by Configure to determine the
3730 full pathname (if any) of the make program. After Configure runs,
3731 the value is reset to a plain "make" and is not useful.
3733 make_set_make (make.U):
3734 Some versions of 'make' set the variable MAKE. Others do not.
3735 This variable contains the string to be included in Makefile.SH
3736 so that MAKE is set if needed, and not if not needed.
3737 Possible values are:
3739 make_set_make='#' # If your make program handles this for you,
3741 make_set_make="MAKE=$make" # if it doesn't.
3743 This uses a comment character so that we can distinguish a
3744 'set' value (from a previous config.sh or Configure '-D' option)
3745 from an uncomputed value.
3747 mallocobj (mallocsrc.U):
3748 This variable contains the name of the malloc.o that this package
3749 generates, if that malloc.o is preferred over the system malloc.
3750 Otherwise the value is null. This variable is intended for generating
3751 Makefiles. See mallocsrc.
3753 mallocsrc (mallocsrc.U):
3754 This variable contains the name of the malloc.c that comes with
3755 the package, if that malloc.c is preferred over the system malloc.
3756 Otherwise the value is null. This variable is intended for generating
3759 malloctype (mallocsrc.U):
3760 This variable contains the kind of ptr returned by malloc and realloc.
3762 man1dir (man1dir.U):
3763 This variable contains the name of the directory in which manual
3764 source pages are to be put. It is the responsibility of the
3765 Makefile.SH to get the value of this into the proper command.
3766 You must be prepared to do the ~name expansion yourself.
3768 man1direxp (man1dir.U):
3769 This variable is the same as the man1dir variable, but is filename
3770 expanded at configuration time, for convenient use in makefiles.
3772 man1ext (man1dir.U):
3773 This variable contains the extension that the manual page should
3774 have: one of 'n', 'l', or '1'. The Makefile must supply the '.'.
3777 man3dir (man3dir.U):
3778 This variable contains the name of the directory in which manual
3779 source pages are to be put. It is the responsibility of the
3780 Makefile.SH to get the value of this into the proper command.
3781 You must be prepared to do the ~name expansion yourself.
3783 man3direxp (man3dir.U):
3784 This variable is the same as the man3dir variable, but is filename
3785 expanded at configuration time, for convenient use in makefiles.
3787 man3ext (man3dir.U):
3788 This variable contains the extension that the manual page should
3789 have: one of 'n', 'l', or '3'. The Makefile must supply the '.'.
3792 mips_type (usrinc.U):
3793 This variable holds the environment type for the mips system.
3794 Possible values are "BSD 4.3" and "System V".
3796 mistrustnm (Csym.U):
3797 This variable can be used to establish a fallthrough for the cases
3798 where nm fails to find a symbol. If usenm is false or usenm is true
3799 and mistrustnm is false, this variable has no effect. If usenm is true
3800 and mistrustnm is "compile", a test program will be compiled to try to
3801 find any symbol that can't be located via nm lookup. If mistrustnm is
3802 "run", the test program will be run as well as being compiled.
3805 This variable is used internally by Configure to determine the
3806 full pathname (if any) of the mkdir program. After Configure runs,
3807 the value is reset to a plain "mkdir" and is not useful.
3809 mmaptype (d_mmap.U):
3810 This symbol contains the type of pointer returned by mmap()
3811 (and simultaneously the type of the first argument).
3812 It can be 'void *' or 'caddr_t'.
3814 modetype (modetype.U):
3815 This variable defines modetype to be something like mode_t,
3816 int, unsigned short, or whatever type is used to declare file
3817 modes for system calls.
3820 This variable is used internally by Configure to determine the
3821 full pathname (if any) of the more program. After Configure runs,
3822 the value is reset to a plain "more" and is not useful.
3824 multiarch (multiarch.U):
3825 This variable conditionally defines the MULTIARCH symbol
3826 which signifies the presence of multiplatform files.
3827 This is normally set by hints files.
3830 This variable is defined but not used by Configure.
3831 The value is the empty string and is not useful.
3833 myarchname (archname.U):
3834 This variable holds the architecture name computed by Configure in
3835 a previous run. It is not intended to be perused by any user and
3836 should never be set in a hint file.
3838 mydomain (myhostname.U):
3839 This variable contains the eventual value of the MYDOMAIN symbol,
3840 which is the domain of the host the program is going to run on.
3841 The domain must be appended to myhostname to form a complete host name.
3842 The dot comes with mydomain, and need not be supplied by the program.
3844 myhostname (myhostname.U):
3845 This variable contains the eventual value of the MYHOSTNAME symbol,
3846 which is the name of the host the program is going to run on.
3847 The domain is not kept with hostname, but must be gotten from mydomain.
3848 The dot comes with mydomain, and need not be supplied by the program.
3850 myuname (Oldconfig.U):
3851 The output of 'uname -a' if available, otherwise the hostname. On Xenix,
3852 pseudo variables assignments in the output are stripped, thank you. The
3853 whole thing is then lower-cased.
3856 This variable contains the '-n' flag if that is what causes the echo
3857 command to suppress newline. Otherwise it is null. Correct usage is
3858 $echo $n "prompt for a question: $c".
3860 need_va_copy (need_va_copy.U):
3861 This symbol, if defined, indicates that the system stores
3862 the variable argument list datatype, va_list, in a format
3863 that cannot be copied by simple assignment, so that some
3864 other means must be used when copying is required.
3865 As such systems vary in their provision (or non-provision)
3866 of copying mechanisms, handy.h defines a platform-
3867 independent macro, Perl_va_copy(src, dst), to do the job.
3869 netdb_hlen_type (netdbtype.U):
3870 This variable holds the type used for the 2nd argument to
3871 gethostbyaddr(). Usually, this is int or size_t or unsigned.
3872 This is only useful if you have gethostbyaddr(), naturally.
3874 netdb_host_type (netdbtype.U):
3875 This variable holds the type used for the 1st argument to
3876 gethostbyaddr(). Usually, this is char * or void *, possibly
3877 with or without a const prefix.
3878 This is only useful if you have gethostbyaddr(), naturally.
3880 netdb_name_type (netdbtype.U):
3881 This variable holds the type used for the argument to
3882 gethostbyname(). Usually, this is char * or const char *.
3883 This is only useful if you have gethostbyname(), naturally.
3885 netdb_net_type (netdbtype.U):
3886 This variable holds the type used for the 1st argument to
3887 getnetbyaddr(). Usually, this is int or long.
3888 This is only useful if you have getnetbyaddr(), naturally.
3891 This variable is used internally by Configure to determine the
3892 full pathname (if any) of the nm program. After Configure runs,
3893 the value is reset to a plain "nm" and is not useful.
3896 This variable holds the options that may be necessary for nm.
3898 nm_so_opt (usenm.U):
3899 This variable holds the options that may be necessary for nm
3900 to work on a shared library but that can not be used on an
3901 archive library. Currently, this is only used by Linux, where
3902 nm --dynamic is *required* to get symbols from an ELF library which
3903 has been stripped, but nm --dynamic is *fatal* on an archive library.
3904 Maybe Linux should just always set usenm=false.
3906 nonxs_ext (Extensions.U):
3907 This variable holds a list of all non-xs extensions included
3908 in the package. All of them will be built.
3911 This variable is used internally by Configure to determine the
3912 full pathname (if any) of the nroff program. After Configure runs,
3913 the value is reset to a plain "nroff" and is not useful.
3915 nv_overflows_integers_at (perlxv.U):
3916 This variable gives the largest integer value that NVs can hold
3917 as a constant floating point expression.
3918 If it could not be determined, it holds the value 0.
3920 nv_preserves_uv_bits (perlxv.U):
3921 This variable indicates how many of bits type uvtype
3922 a variable nvtype can preserve.
3924 nveformat (perlxvf.U):
3925 This variable contains the format string used for printing
3926 a Perl NV using %e-ish floating point format.
3928 nvEUformat (perlxvf.U):
3929 This variable contains the format string used for printing
3930 a Perl NV using %E-ish floating point format.
3932 nvfformat (perlxvf.U):
3933 This variable confains the format string used for printing
3934 a Perl NV using %f-ish floating point format.
3936 nvFUformat (perlxvf.U):
3937 This variable confains the format string used for printing
3938 a Perl NV using %F-ish floating point format.
3940 nvgformat (perlxvf.U):
3941 This variable contains the format string used for printing
3942 a Perl NV using %g-ish floating point format.
3944 nvGUformat (perlxvf.U):
3945 This variable contains the format string used for printing
3946 a Perl NV using %G-ish floating point format.
3949 This variable is the size of an NV in bytes.
3952 This variable contains the C type used for Perl's NV.
3954 o_nonblock (nblock_io.U):
3955 This variable bears the symbol value to be used during open() or fcntl()
3956 to turn on non-blocking I/O for a file descriptor. If you wish to switch
3957 between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead,
3958 but that is only supported by some devices.
3961 This is an old synonym for _o.
3963 old_pthread_create_joinable (d_pthrattrj.U):
3964 This variable defines the constant to use for creating joinable
3965 (aka undetached) pthreads. Unused if pthread.h defines
3966 PTHREAD_CREATE_JOINABLE. If used, possible values are
3967 PTHREAD_CREATE_UNDETACHED and __UNDETACHED.
3969 optimize (ccflags.U):
3970 This variable contains any optimizer/debugger flag that should be used.
3971 It is up to the Makefile to use it.
3973 orderlib (orderlib.U):
3974 This variable is "true" if the components of libraries must be ordered
3975 (with `lorder $* | tsort`) before placing them in an archive. Set to
3976 "false" if ranlib or ar can generate random libraries.
3978 osname (Oldconfig.U):
3979 This variable contains the operating system name (e.g. sunos,
3980 solaris, hpux, etc.). It can be useful later on for setting
3981 defaults. Any spaces are replaced with underscores. It is set
3982 to a null string if we can't figure it out.
3984 osvers (Oldconfig.U):
3985 This variable contains the operating system version (e.g.
3986 4.1.3, 5.2, etc.). It is primarily used for helping select
3987 an appropriate hints file, but might be useful elsewhere for
3988 setting defaults. It is set to '' if we can't figure it out.
3989 We try to be flexible about how much of the version number
3990 to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the
3991 same for this package, hints files might just be os_4.0 or
3992 os_4.1, etc., not keeping separate files for each little release.
3994 otherlibdirs (otherlibdirs.U):
3995 This variable contains a colon-separated set of paths for the perl
3996 binary to search for additional library files or modules.
3997 These directories will be tacked to the end of @INC.
3998 Perl will automatically search below each path for version-
3999 and architecture-specific directories. See inc_version_list
4001 A value of ' ' means 'none' and is used to preserve this value
4002 for the next run through Configure.
4004 package (package.U):
4005 This variable contains the name of the package being constructed.
4006 It is primarily intended for the use of later Configure units.
4009 This variable contains the name of the preferred pager on the system.
4010 Usual values are (the full pathnames of) more, less, pg, or cat.
4013 This variable contains a command that produces the text of the
4014 /etc/passwd file. This is normally "cat /etc/passwd", but can be
4015 "ypcat passwd" when NIS is used.
4016 On some systems, such as os390, there may be no equivalent
4017 command, in which case this variable is unset.
4019 patchlevel (patchlevel.U):
4020 The patchlevel level of this package.
4021 The value of patchlevel comes from the patchlevel.h file.
4022 In a version number such as 5.6.1, this is the "6".
4023 In patchlevel.h, this is referred to as "PERL_VERSION".
4026 This is an old synonym for p_ in Head.U, the character
4027 used to separate elements in the command shell search PATH.
4030 This variable is defined but not used by Configure.
4031 The value is the empty string and is not useful.
4034 This variable contains the full path (if any) to a previously
4035 installed perl5.005 or later suitable for running the script
4036 to determine inc_version_list.
4038 PERL_API_REVISION (patchlevel.h):
4039 This number describes the earliest compatible PERL_REVISION of
4040 Perl ("compatibility" here being defined as sufficient binary/API
4041 compatibility to run XS code built with the older version).

4099 which contains the name of the perl interpreter to be used in
4100 shell scripts and in the "eval 'exec'" idiom. This variable is
4101 not necessarily the pathname of the file containing the perl
4102 interpreter; you must append the executable extension (_exe) if
4103 it is not already present. Note that Perl code that runs during

4203 This variable holds the return code from read() when no data is
4204 present. It should be -1, but some systems return 0 when O_NDELAY is

4278 the latter. This is only useful if you have select(), naturally.
4280 selecttype (selecttype.U):
4281 This variable holds the type used for the 2nd, 3rd, and 4th
4282 arguments to select. Usually, this is 'fd_set *', if HAS_FD_SET

4903 and indicates that 64-bit integer types should be used
4904 when available. The maximal possible
4905 64-bitness is employed: LP64 or ILP64, meaning that you will
4906 be able to use more than 2 gigabytes of memory. This mode is
4907 even more binary incompatible than USE_64_BIT_INT. You may not
4908 be able to run the resulting executable in a 32-bit CPU at all or
4909 you may need at least to reboot your OS to 64-bit mode.
4911 use64bitint (use64bits.U):
4912 This variable conditionally defines the USE_64_BIT_INT symbol,
4913 and indicates that 64-bit integer types should be used
4914 when available. The minimal possible 64-bitness
4915 is employed, just enough to get 64-bit integers into Perl.
4916 This may mean using for example "long longs", while your memory
4917 may still be limited to 2 gigabytes.

4920 This variable conditionally defines the USE_CROSS_COMPILE symbol,
4921 and indicates that Perl has been cross-compiled.

4965 and indicates that Perl should be built to use multiplicity.
4967 usemymalloc (mallocsrc.U):
4968 This variable contains y if the malloc that comes with this package
4969 is desired over the system's version of malloc. People often include
4970 special versions of malloc for effiency, but such versions are often
4971 less portable. See also mallocsrc and mallocobj.
4972 If this is 'y', then -lmalloc is removed from $libs.
4975 This variable contains 'true' or 'false' depending whether the
4976 nm extraction is wanted or not.
4978 useopcode (Extensions.U):
4979 This variable holds either 'true' or 'false' to indicate

4985 useperlio (useperlio.U):
4986 This variable conditionally defines the USE_PERLIO symbol,
4987 and indicates that the PerlIO abstraction should be
4990 useposix (Extensions.U):
4991 This variable holds either 'true' or 'false' to indicate
4992 whether the POSIX extension should be used. The sole
4993 use for this currently is to allow an easy mechanism
4994 for hints files to indicate that POSIX will not compile
4995 on a particular system.
4997 usereentrant (usethreads.U):
4998 This variable conditionally defines the USE_REENTRANT_API symbol,
4999 which indicates that the thread code may try to use the various
5000 _r versions of library functions. This is only potentially
5001 meaningful if usethreads is set and is very experimental, it is
5002 not even prompted for.
5004 userelocatableinc (bin.U):
5005 This variable is set to true to indicate that perl should relocate
5006 @INC entries at runtime based on the path to the perl binary.
5007 Any @INC paths starting ".../" are relocated relative to the directory
5008 containing the perl binary, and a logical cleanup of the path is then
5009 made around the join point (removing "dir/../" pairs)
5012 This variable is set to true when the user agrees to use sfio.
5013 It is set to false when sfio is not available or when the user
5014 explicitely requests not to use sfio. It is here primarily so
5015 that command-line settings can override the auto-detection of
5016 d_sfio without running into a "WHOA THERE".
5018 useshrplib (libperl.U):
5019 This variable is set to 'true' if the user wishes
5020 to build a shared libperl, and 'false' otherwise.

5041 It is set to false when no vfork is available or when the user
5042 explicitely requests not to use vfork.
5045 This variable holds the path of the include files, which is
5046 usually /usr/include. It is mainly used by other Configure units.
5049 This variable is defined but not used by Configure.
5050 The value is the empty string and is not useful.

5193 The full version number of this package, such as 5.6.1 (or 5_6_1).
5194 This combines revision, patchlevel, and subversion to get the
5195 full version number, including any possible subversions.
5196 This is suitable for use as a directory name, and hence is
5197 filesystem dependent.
5199 version_patchlevel_string (patchlevel.U):
5200 This is a string combining version, subversion and
5201 perl_patchlevel (if perl_patchlevel is non-zero).
5202 It is typically something like
5203 'version 7 subversion 1' or
5204 'version 7 subversion 1 patchlevel 11224'
5205 It is computed here to avoid duplication of code in myconfig.SH
5208 versiononly (versiononly.U):
5209 If set, this symbol indicates that only the version-specific
5210 components of a perl installation should be installed.
5211 This may be useful for making a test installation of a new
5212 version without disturbing the existing installation.
5213 Setting versiononly is equivalent to setting installperl's -v option.
5214 In particular, the non-versioned scripts and programs such as
5215 a2p, c2ph, h2xs, pod2*, and perldoc are not installed
5216 (see INSTALL for a more complete list). Nor are the man
5218 Usually, this is undef.
5221 This variable is defined but not used by Configure.
5222 The value is the empty string and is not useful.
5224 voidflags (voidflags.U):
5225 This variable contains the eventual value of the VOIDFLAGS symbol,
5226 which indicates how much support of the void type is given by this
5227 compiler. See VOIDFLAGS for more info.
5230 This variable holds extra path (space-separated) used to find
5231 libraries on this platform, for example CPU-specific libraries
5232 (on multi-CPU platforms) may be listed here.
5235 This variable holds the name of the compiler compiler we
5236 want to use in the Makefile. It can be yacc, byacc, or bison -y.
5239 This variable contains any additional yacc flags desired by the
5240 user. It is up to the Makefile to use this.
5243 This variable is defined but not used by Configure.
5244 The value is the empty string and is not useful.
5247 This variable is used internally by Configure to determine the
5248 full pathname (if any) of the zip program. After Configure runs,
5249 the value is reset to a plain "zip" and is not useful.
