Linux From Scratch - Version 6.1

Chapter 6. Installing Basic System Software

6.33. Perl-5.8.6

The Perl package contains the Practical Extraction and Report Language.

Approximate build time: 2.9 SBU
Required disk space: 137 MB
Installation depends on: Bash, Binutils, Coreutils, Diffutils, Gawk, GCC, Glibc, Grep, Make, and Sed

6.33.1. Installation of Perl

To have full control over the way Perl is set up, run the interactive Configure script and hand-pick the way this package is built. If the defaults it auto-detects are suitable, prepare Perl for compilation with: 

./configure.gnu --prefix=/usr -Dpager="/bin/less -isR"

The meaning of the configure options:

-Dpager="/bin/less -isR"

This corrects an error in the perldoc code with the invocation of the less program.

Compile the package: 

make

To run the test suite, first create a basic /etc/hosts file which is needed by a couple of the tests to resolve the network name localhost: 

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

Now run the tests, if desired: 

make test

Install the package: 

make install
