This file contains a description of all the shell variables whose value is
determined by the Configure script. Variables intended for use in C
programs (e.g. I_UNISTD) are already described in config_h.SH. [`configpm'
the formatting regular.]
_a (Unix.U):
- This variable defines the extension used for ordinary libraries.
+ This variable defines the extension used for ordinary library files.
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'.
+ DJGPP, Cygwin and OS/2 use '.exe'. Stratus VOS uses '.pm'.
+ On operating systems which do not require a specific extension
+ for executable files, this variable is empty.
_o (Unix.U):
This variable defines the extension used for object files.
with a hint value or command line option, but you'd better know
what you are doing.
+afsroot (afs.U):
+ This variable is by default set to '/afs'. In the unlikely case
+ this is not the correct root, it is possible to override this with
+ a hint value or command line option. This will be used in subsequent
+ tests for AFSness in the Perl configure and test process.
+
alignbytes (alignbytes.U):
This variable holds the number of bytes required to align a
- double. Usual values are 2, 4 and 8.
+ 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.
host name. The command is fully qualified by its absolute path, to make
it safe when used by a process with super-user privileges.
-apiversion (patchlevel.U):
- This is a number which identifies the lowest version of perl
- to have an API (for XS extensions) compatible with the present
- version. For example, for 5.005_01, the apiversion should be
- 5.005, since 5.005_01 should be binary compatible with 5.005.
- This should probably be incremented manually somehow, perhaps
- from patchlevel.h. For now, we'll guess maintenance subversions
- will retain binary compatibility.
+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. This is filesystem dependent.

which the vendor will install add-on packages.
+ See INSTALL for usage and examples.
vendorprefixexp (vendorprefix.U):
This variable holds the full absolute path of the directory below
which the vendor will install add-on packages. Derived from vendorprefix.

version (patchlevel.U):
- The full version number of this package. This combines
- baserev, patchlevel, and subversion to get the full
- version number, including any possible subversions. Care
- is taken to use the C locale in order to get something
- like 5.004 instead of 5,004. This is unique to perl.
+ The full version number of this package, such as 5.6.1 (or 5_6_1).
+ This combines revision, patchlevel, and subversion to get the
+ full version number, including any possible subversions.
+ This is suitable for use as a directory name, and hence is
+ filesystem dependent.
+
+version_patchlevel_string (patchlevel.U):
+ This is a string combining version, subversion and
+ perl_patchlevel (if perl_patchlevel is non-zero).
+ It is typically something like
+ 'version 7 subversion 1' or
+ 'version 7 subversion 1 patchlevel 11224'
+ It is computed here to avoid duplication of code in myconfig.SH
+ and lib/Config.pm.
+
+versiononly (versiononly.U):
+ If set, this symbol indicates that only the version-specific
+ components of a perl installation should be installed.
+ This may be useful for making a test installation of a new
+ version without disturbing the existing installation.
+ Setting versiononly is equivalent to setting installperl's -v option.
+ In particular, the non-versioned scripts and programs such as
+ a2p, c2ph, h2xs, pod2*, and perldoc are not installed
+ (see INSTALL for a more complete list). Nor are the man
+ pages installed.
+ Usually, this is undef.
