Variables intended for use in C -programs (e.g. I_UNISTD) are already described in config_h.SH. [`configpm' -generates pod documentation for Config.pm from this file--please try to keep -the formatting regular.] - -_a (Unix.U): - This variable defines the extension used for ordinary libraries. - For unix, it is '.a'. The '.' is included. Other possible - values include '.lib'. - -_exe (Unix.U): - This variable defines the extension used for executable files. - For unix it is empty. Other possible values include '.exe'. - -_o (Unix.U): - This variable defines the extension used for object files. - For unix, it is '.o'. The '.' is included. Other possible - values include '.obj'. - -afs (afs.U): - This variable is set to 'true' if AFS (Andrew File System) is used - on the system, 'false' otherwise. It is possible to override this - with a hint value or command line option, but you'd better know - what you are doing. - -alignbytes (alignbytes.U): - This variable holds the number of bytes required to align a - double-- or a long double when applicable. Usual values are - 2, 4 and 8. The default is eight, for safety. - -ansi2knr (ansi2knr.U): - This variable is set if the user needs to run ansi2knr. - Currently, this is not supported, so we just abort. - -aphostname (d_gethname.U): - This variable contains the command which can be used to compute the - host name. The command is fully qualified by its absolute path, to make - it safe when used by a process with super-user privileges. - -api_revision (patchlevel.U): - The three variables, api_revision, api_version, and - api_subversion, specify the version of the oldest perl binary - compatible with the present perl. In a full version string - such as '5.6.1', api_revision is the '5'. - Prior to 5.5.640, the format was a floating point number, - like 5.00563. - perl.c:incpush() and lib/lib.pm will automatically search in - $sitelib/.. for older directories back to the limit specified - by these api_ variables. This is only useful if you have a - perl library directory tree structured like the default one. - See INSTALL for how this works. The versioned site_perl - directory was introduced in 5.005, so that is the lowest - possible value. The version list appropriate for the current - system is determined in inc_version_list.U. - XXX To do: Since compatibility can depend on compile time - options (such as bincompat, longlong, etc.) it should - (perhaps) be set by Configure, but currently it isn't. - Currently, we read a hard-wired value from patchlevel.h. - Perhaps what we ought to do is take the hard-wired value from - patchlevel.h but then modify it if the current Configure - options warrant. patchlevel.h then would use an #ifdef guard. - -api_subversion (patchlevel.U): - The three variables, api_revision, api_version, and - api_subversion, specify the version of the oldest perl binary - compatible with the present perl. In a full version string - such as '5.6.1', api_subversion is the '1'. See api_revision for - full details. - -api_version (patchlevel.U): - The three variables, api_revision, api_version, and - api_subversion, specify the version of the oldest perl binary - compatible with the present perl. In a full version string - such as '5.6.1', api_version is the '6'. See api_revision for - full details. As a special case, 5.5.0 is rendered in the - old-style as 5.005. (In the 5.005_0x maintenance series, - this was the only versioned directory in $sitelib.) - -api_versionstring (patchlevel.U): - This variable combines api_revision, api_version, and - api_subversion in a format such as 5.6.1 (or 5_6_1) suitable - for use as a directory name.

(That is, pure perl modules - written for $pm_apiversion will still work for the current - version). perl.c:incpush() and lib/lib.pm will automatically - search in $sitelib for older directories across major versions - back to pm_apiversion. This is only useful if you have a perl - library directory tree structured like the default one. The - versioned site_perl library was introduced in 5.005, so that's - the default setting for this variable. It's hard to imagine - it changing before Perl6.

Nor are the man - pages installed. - Usually, this is undef. - -vi (Loc.U): - This variable is defined but not used by Configure. - The value is a plain '' and is not useful. - -voidflags (voidflags.U): - This variable contains the eventual value of the VOIDFLAGS symbol, - which indicates how much support of the void type is given by this - compiler. See VOIDFLAGS for more info. - -xlibpth (libpth.U): - This variable holds extra path (space-separated) used to find - libraries on this platform, for example CPU-specific libraries - (on multi-CPU platforms) may be listed here. - -xs_apiversion (xs_apiversion.U): - This variable contains the version of the oldest perl binary - compatible with the present perl. perl.c:incpush() and - lib/lib.pm will automatically search in $sitearch for older - directories across major versions back to xs_apiversion. - This is only useful if you have a perl library directory tree - structured like the default one. - See INSTALL for how this works. - The versioned site_perl directory was introduced in 5.005, - so that is the lowest possible value. - Since this can depend on compile time options (such as - bincompat) it is set by Configure. Other non-default sources - of potential incompatibility, such as multiplicity, threads, - debugging, 64bits, sfio, etc., are not checked for currently, - though in principle we could go snooping around in old - Config.pm files. - -zcat (Loc.U): - This variable is defined but not used by Configure. - The value is a plain '' and is not useful. - -zip (Loc.U): - This variable is used internally by Configure to determine the - full pathname (if any) of the zip program. After Configure runs, - the value is reset to a plain "zip" and is not useful. - |
