NAME

       perllinux - Perl version 5 on Linux systems


DESCRIPTION

       This document describes various features of Linux that will affect how
       Perl version 5 (hereafter just Perl) is compiled and/or runs.

   Deploying Perl on Linux
       Normally one can install /usr/bin/perl on Linux using your
       distribution's package manager (e.g: "sudo apt-get install perl", or
       "sudo dnf install perl"). Note that sometimes one needs to install some
       extra system packages in order to be able to use CPAN frontends, and
       that messing with the system's perl is not always recommended. One can
       use perlbrew <https://perlbrew.pl/> to avoid such issues.

       Otherwise, perl should build fine on Linux using the mainstream
       compilers GCC and clang, while following the usual instructions.

   Experimental Support for Sun Studio Compilers for Linux OS
       Sun Microsystems has released a port of their Sun Studio compilers for
       Linux.  As of May 2019, the last stable release took place on 2017, and
       one can buy support contracts for them.

       There are some special instructions for building Perl with Sun Studio
       on Linux.  Following the normal "Configure", you have to run make as
       follows:

           LDLOADLIBS=-lc make

       "LDLOADLIBS" is an environment variable used by the linker to link
       "/ext" modules to glibc.  Currently, that environment variable is not
       getting populated by a combination of "Config" entries and
       "ExtUtil::MakeMaker".  While there may be a bug somewhere in Perl's
       configuration or "ExtUtil::MakeMaker" causing the problem, the most
       likely cause is an incomplete understanding of Sun Studio by this
       author.  Further investigation is needed to get this working better.
