Глава 6. Установка базовых системных пакетов

6.37. Perl-5.16.2

The Perl package contains the Practical Extraction and Report Language.

Приблизительное время сборки: 7.5 SBU
Требует свободного места на диске: 247 MB

6.37.1. Установка 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

This version of Perl now builds the Compress::Raw::Zlib module. By default Perl will use an internal copy of the Zlib source for the build. Issue the following command so that Perl will use the Zlib library installed on the system: 

sed -i -e "s|BUILD_ZLIB\s*= True|BUILD_ZLIB = False|"           \
       -e "s|INCLUDE\s*= ./zlib-src|INCLUDE    = /usr/include|" \
       -e "s|LIB\s*= ./zlib-src|LIB        = /usr/lib|"         \
    cpan/Compress-Raw-Zlib/config.in

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"  \
                  -Duseshrplib

Значение параметров configure:

-Dvendorprefix=/usr

This ensures perl knows how to tell packages where they should install their perl modules.

-Dpager="/usr/bin/less -isR"

This corrects an error in the way that perldoc invokes the less program.

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

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

-Duseshrplib

Build a shared libperl needed by some perl modules.

Cкомпилируем пакет: 

make

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

make -k test

Установим пакет: 

make install
