6.45. Perl-5.20.2

6.45.1. Installation of Perl

First create a basic /etc/hosts file to be referenced in one of Perl's configuration files as well as the optional test suite:

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

Perl does not, by default, know about library directories with names other than lib, The following patch will allow it to install to other directories:

patch -Np1 -i ../perl-5.20.2-Configure_multilib-2.patch

Back up the hints/linux.sh and cpan/Compress-Raw-Zlib/config.in files so they can be reset between platforms:

cp -v hints/linux.sh hints/linux.sh.bak
cp -v cpan/Compress-Raw-Zlib/config.in cpan/Compress-Raw-Zlib/config.in.bak

6.45.2. 32-bit Installation

This version of Perl now builds the Compress::Raw::Zlib and Compress::Raw::BZip2 modules. By default Perl will use an internal copy of the sources for the build. Issue the following command so that Perl will use the libraries installed on the system:

export BUILD_ZLIB=False
export BUILD_BZIP2=0

There is a further (possibly cosmetic) anomaly - if we install perl and then run perl -V it will claim that libc is in /lib. The following sed fixes this, but only takes effect when make install is run:

sed -i "/libc/s@/lib@/lib32@" hints/linux.sh

We still need to tell perl to actually use lib32:

echo 'installstyle="lib32/perl5"' >>hints/linux.sh

To have full control over the way Perl is set up, you can remove the “-des” options from the following command and hand-pick the way this package is built. Alternatively, use the command exactly as below to use the defaults that Perl auto-detects:

sh Configure -des -Dprefix=/usr                 \
                  -Dvendorprefix=/usr           \
                  -Dman1dir=/usr/share/man/man1 \
                  -Dman3dir=/usr/share/man/man3 \
                  -Dpager="/usr/bin/less -isR"  \
                  -Dlibpth="/usr/local/lib32 /lib32 /usr/lib32" \
                  -Dcc="gcc -m32" \
                  -Duseshrplib

Compile the package:

make

To test the results (approximately 2.5 SBU), issue:

make -k test

Install the package and clean up:

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/perl5.20.2{,-32}

Clean up the build directory and restore the hints/linux.sh and cpan/Compress-Raw-Zlib/config.in files before moving on to the next platform:

make distclean
cp -v hints/linux.sh.bak hints/linux.sh
cp -v cpan/Compress-Raw-Zlib/config.in.bak cpan/Compress-Raw-Zlib/config.in

6.45.3. x32 ABI Installation

This version of Perl now builds the Compress::Raw::Zlib and Compress::Raw::BZip2 modules. By default Perl will use an internal copy of the sources for the build. Issue the following command so that Perl will use the libraries installed on the system:

export BUILD_ZLIB=False
export BUILD_BZIP2=0

sed -i "/libc/s@/lib@/libx32@" hints/linux.sh

We still need to tell perl to actually use libx32:

echo 'installstyle="libx32/perl5"' >>hints/linux.sh

To have full control over the way Perl is set up, you can remove the “-des” options from the following command and hand-pick the way this package is built. Alternatively, use the command exactly as below to use the defaults that Perl auto-detects:

sh Configure -des -Dprefix=/usr                 \
                  -Dvendorprefix=/usr           \
                  -Dman1dir=/usr/share/man/man1 \
                  -Dman3dir=/usr/share/man/man3 \
                  -Dpager="/usr/bin/less -isR"  \
                  -Dlibpth="/usr/local/libx32 /libx32 /usr/libx32" \
                  -Dcc="gcc -mx32" \
                  -Duseshrplib

Compile the package:

make

To test the results (approximately 2.5 SBU), issue:

make -k test

Install the package and clean up:

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{,-x32}
mv -v /usr/bin/perl5.20.2{,-x32}

make distclean
cp -v hints/linux.sh.bak hints/linux.sh
cp -v cpan/Compress-Raw-Zlib/config.in.bak cpan/Compress-Raw-Zlib/config.in

6.45.4. 64-bit Installation

This version of Perl now builds the Compress::Raw::Zlib and Compress::Raw::BZip2 modules. By default Perl will use an internal copy of the sources for the build. Issue the following command so that Perl will use the libraries installed on the system:

export BUILD_ZLIB=False
export BUILD_BZIP2=0

sh Configure -des -Dprefix=/usr                 \
                  -Dvendorprefix=/usr           \
                  -Dman1dir=/usr/share/man/man1 \
                  -Dman3dir=/usr/share/man/man3 \
                  -Dpager="/usr/bin/less -isR"  \
                  -Duseshrplib

Compile the package:

make

To test the results (approximately 2.5 SBU), issue:

make -k test

Install the package and clean up:

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{,-64}
mv -v /usr/bin/perl5.20.2{,-64}

Now we need to create a link to the multiarch wrapper that lets us choose which perl installation to use:

ln -sv multiarch_wrapper /usr/bin/perl
ln -sv multiarch_wrapper /usr/bin/perl5.20.2

The value of the USE_ARCH environment variable will decide which perl binary to execute. USE_ARCH=32 perl -V:cc will give the value of CC used to build the 32bit perl. The multiarch_wrapper will help later with building perl extensions and bindings. Without the multiarch_wrapper it is very hard to setup a 32bit extension or binding.
