=head1 NAME
|
|
|
|
Config - access Perl configuration information
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use Config;
|
|
if ($Config{'cc'} =~ /gcc/) {
|
|
print "built by gcc\n";
|
|
}
|
|
|
|
use Config qw(myconfig config_sh config_vars);
|
|
|
|
print myconfig();
|
|
|
|
print config_sh();
|
|
|
|
config_vars(qw(osname archname));
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The Config module contains all the information that was available to
|
|
the C<Configure> program at Perl build time (over 900 values).
|
|
|
|
Shell variables from the F<config.sh> file (written by Configure) are
|
|
stored in the readonly-variable C<%Config>, indexed by their names.
|
|
|
|
Values stored in config.sh as 'undef' are returned as undefined
|
|
values. The perl C<exists> function can be used to check if a
|
|
named variable exists.
|
|
|
|
=over 4
|
|
|
|
=item myconfig()
|
|
|
|
Returns a textual summary of the major perl configuration values.
|
|
See also C<-V> in L<perlrun/Switches>.
|
|
|
|
=item config_sh()
|
|
|
|
Returns the entire perl configuration information in the form of the
|
|
original config.sh shell variable assignment script.
|
|
|
|
=item config_vars(@names)
|
|
|
|
Prints to STDOUT the values of the named configuration variable. Each is
|
|
printed on a separate line in the form:
|
|
|
|
name='value';
|
|
|
|
Names which are unknown are output as C<name='UNKNOWN';>.
|
|
See also C<-V:name> in L<perlrun/Switches>.

=head1 EXAMPLE
|
|
|
|
Here's a more sophisticated example of using %Config:
|
|
|
|
use Config;
|
|
use strict;
|
|
|
|
my %sig_num;
|
|
my @sig_name;
|
|
unless($Config{sig_name} && $Config{sig_num}) {
|
|
die "No sigs?";
|
|
} else {
|
|
my @names = split ' ', $Config{sig_name};
|
|
@sig_num{@names} = split ' ', $Config{sig_num};
|
|
foreach (@names) {
|
|
$sig_name[$sig_num{$_}] ||= $_;
|
|
}
|
|
}
|
|
|
|
print "signal #17 = $sig_name[17]\n";
|
|
if ($sig_num{ALRM}) {
|
|
print "SIGALRM is $sig_num{ALRM}\n";
|
|
}
|
|
|
|
=head1 WARNING
|
|
|
|
Because this information is not stored within the perl executable
|
|
itself it is possible (but unlikely) that the information does not
|
|
relate to the actual perl binary which is being used to access it.
|
|
|
|
The Config module is installed into the architecture and version
|
|
specific library directory ($Config{installarchlib}) and it checks the
|
|
perl version number when loaded.
|
|
|
|
The values stored in config.sh may be either single-quoted or
|
|
double-quoted. Double-quoted strings are handy for those cases where you
|
|
need to include escape sequences in the strings. To avoid runtime variable
|
|
interpolation, any C<$> and C<@> characters are replaced by C<\$> and
|
|
C<\@>, respectively. This isn't foolproof, of course, so don't embed C<\$>
|
|
or C<\@> in double-quoted strings unless you're willing to deal with the
|
|
consequences. (The slashes will end up escaped and the C<$> or C<@> will
|
|
trigger variable interpolation)
|
|
|
|
=head1 GLOSSARY
|
|
|
|
Most C<Config> variables are determined by the C<Configure> script
|
|
on platforms supported by it (which is most UNIX platforms). Some
|
|
platforms have custom-made C<Config> variables, and may thus not have
|
|
some of the variables described below, or may have extraneous variables
|
|
specific to that particular port. See the port specific documentation
|
|
in such cases.

|
|
|
|
From F<Loc.U>:
|
|
|
|
This variable is be used internally by Configure to determine the
|
|
full pathname (if any) of the Mcc program. After Configure runs,
|
|
the value is reset to a plain C<Mcc> and is not useful.

|
|
|
|
From F<Unix.U>:
|
|
|
|
This variable defines the extension used for ordinary libraries.
|
|
For unix, it is F<.a>. The F<.> is included. Other possible
|
|
values include F<.lib>.
|
|
|
|
=item C<_exe>
|
|
|

|
This variable defines the extension used for executable files.
|
|
For unix it is empty. Other possible values include F<.exe>.
|
|
|
|
=item C<_o>
|
|
|
|
From F<Unix.U>:
|
|
|
|
This variable defines the extension used for object files.
|

=item C<afs>
|
|
|
|
From F<afs.U>:
|
|
|
|
This variable is set to C<true> if C<AFS> (Andrew File System) is used
|
|
on the system, C<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.
|
|
|
|
=item C<alignbytes>
|
|
|
|
From F<alignbytes.U>:
|
|
|
|
This variable holds the number of bytes required to align a
|
|
double. Usual values are 2, 4 and 8.
|
|
|
|
=item C<ansi2knr>
|
|
|
|
From F<ansi2knr.U>:
|
|
|
|
This variable is set if the user needs to run ansi2knr.
|
|
Currently, this is not supported, so we just abort.
|
|
|
|
=item C<aphostname>
|
|
|
|
From F<d_gethname.U>:
|
|
|
|
Thie 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.
|
|
|
|
=item C<apiversion>
|
|
|
|
From F<patchlevel.U>:
|
|
|
|
This is a number which identifies the lowest version of perl
|
|
to have an C<API> (for C<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 F<patchlevel.h>. For now, we'll guess maintenance subversions
|
|
will retain binary compatibility.
|
|
|
|
=item C<ar>
|
|
|
|
From F<Loc.U>:
|
|
|
|
This variable is be used internally by Configure to determine the

|
|
the value is reset to a plain C<ar> and is not useful.
|
|
|
|
=item C<archlib>
|
|
|
|
From F<archlib.U>:
|
|
|
|
This variable holds the name of the directory in which the user wants
|
|
to put architecture-dependent public library files for $package.
|
|
It is most often a local directory such as F</usr/local/lib>.
|
|
Programs using this variable must be prepared to deal
|
|
with filename expansion.
|
|
|
|
=item C<archlibexp>
|
|
|
|
From F<archlib.U>:
|
|
|
|
This variable is the same as the archlib variable, but is
|
|
filename expanded at configuration time, for convenient use.
|
|
|
|
=item C<archname>
|
|
|
|
From F<archname.U>:
|
|
|
|
This variable is a short name to characterize the current
|
|
architecture. It is used mainly to construct the default archlib.
|
|
|
|
=item C<archobjs>
|
|
|
|
From F<Unix.U>:
|
|
|
|
This variable defines any additional objects that must be linked
|
|
in with the program on this architecture. On unix, it is usually
|
|
empty. It is typically used to include emulations of unix calls
|
|
or other facilities. For perl on F<OS/2>, for example, this would
|
|
include F<os2/os2.obj>.
|
|
|
|

|
|
|
From F<Loc.U>:
|

|
|
This variable is be used internally by Configure to determine the

We try to be flexible about how much of the version number
|
|
to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the

This variable contains the full pathname of the shell used
|
|
on this system to execute Bourne shell scripts. Usually, this will be
|
|
F</bin/sh>, though it's possible that some systems will have F</bin/ksh>,
|
|
F</bin/pdksh>, F</bin/ash>, F</bin/bash>, or even something such as
|
|
D:F</bin/sh.exe>.
|
|
This unit comes before F<Options.U>, so you can't set sh with a C<-D>
|
|
option, though you can override this (and startsh)
|
|
with C<-O -Dsh=F</bin/whatever> -Dstartsh=whatever>

=item C<shrpenv>
|

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