10.72. Perl-5.26.0 32 Bit Libraries

The Perl package contains the Practical Extraction and Report Language.

10.72.1. Installation of Perl

By default, Perl's Compress::Raw::Zlib and Compress::Raw::Bzip2 modules build and link against internal copies of Zlib and Bzip2. The following command will make Perl use the system-installed copies of these libraries:

export BUILD_ZLIB=False
export BUILD_BZIP2=0
[Note]

Note

If you are following the boot method you will need to enable the loopback device:

ip link set lo up

Before starting to configure, create a basic /etc/hosts file which will be referenced by one of Perl's configuration files as well as used by the test suite:

echo "127.0.0.1 localhost $(hostname)" > /etc/hosts

To have full control over the way Perl is set up, you can run the interactive Configure script and hand-pick the way this package is built. If you prefer instead to use the defaults that Perl auto-detects, prepare Perl for compilation with:

./configure.gnu \
    --prefix=/usr \
    -Dvendorprefix=/usr \
    -Dman1dir=/usr/share/man/man1 \
    -Dman3dir=/usr/share/man/man3 \
    -Dpager="/bin/less -isR" \
    -Dcc="gcc ${BUILD32}" \
    -Dusethreads \
    -Duseshrplib

The meaning of the configure option:

-Dman1dir=/usr/share/man/man1 -Dman3dir=/usr/share/man/man3

Since Groff is not installed yet, configure.gnu thinks that we do not want man pages for Perl. Issuing these parameters overrides this decision.

-Dpager="/bin/less -isR"

Less has not yet been installed, so by default perldoc will invoke the more program for viewing documentation. This option ensures that it will use less instead.

-Dusethreads

This tells Perl to use threads.

-Duseshrplib

This tells Perl to build a shared libperl.

Compile the package:

make

To test the results, issue:

make test

Install the package and remove the variables set previously:

make install
unset BUILD_ZLIB BUILD_BZIP2

Add a suffix to the perl binary which will be used by the multiarch wrapper:

mv -v /usr/bin/perl{,-32}
mv -v /usr/bin/perl5.26.0{,-32}
