| | 5 | =head1 NAME |
| | 6 | |
| | 7 | perllinux - Perl version 5 on Linux systems |
| | 8 | |
| | 9 | =head1 DESCRIPTION |
| | 10 | |
| | 11 | This document describes various features of Linux that will affect how Perl |
| | 12 | version 5 (hereafter just Perl) is compiled and/or runs. |
| | 13 | |
| | 14 | =head2 Deploying Perl on Linux |
| | 15 | |
| | 16 | Normally one can install F</usr/bin/perl> on Linux using your distribution's |
| | 17 | package manager (e.g: C<sudo apt-get install perl>, or |
| | 18 | C<sudo dnf install perl>). Note that sometimes one needs to install some |
| | 19 | extra system packages in order to be able to use CPAN frontends, and that |
| | 20 | messing with the system's perl is not always recommended. One can use |
| | 21 | L<perlbrew|https://perlbrew.pl/> to avoid such issues. |
| | 22 | |
| | 23 | Otherwise, perl should build fine on Linux using the mainstream compilers |
| | 24 | GCC and clang, while following the usual instructions. |
| | 25 | |
| | 26 | =head2 Experimental Support for Sun Studio Compilers for Linux OS |
| | 27 | |
| | 28 | Sun Microsystems has released a port of their Sun Studio compilers for |
| | 29 | Linux. As of May 2019, the last stable release took place on 2017, and one can |
| | 30 | buy support contracts for them. |
| | 31 | |
| | 32 | There are some special instructions for building Perl with Sun Studio on |
| | 33 | Linux. Following the normal C<Configure>, you have to run make as follows: |
| | 34 | |
| | 35 | LDLOADLIBS=-lc make |
| | 36 | |
| | 37 | C<LDLOADLIBS> is an environment variable used by the linker to link |
| | 38 | C</ext> modules to glibc. Currently, that environment variable is not getting |
| | 39 | populated by a combination of C<Config> entries and C<ExtUtil::MakeMaker>. |
| | 40 | While there may be a bug somewhere in Perl's configuration or |
| | 41 | C<ExtUtil::MakeMaker> causing the problem, the most likely cause is an |
| | 42 | incomplete understanding of Sun Studio by this author. Further investigation |
| | 43 | is needed to get this working better. |
