perllinux − Perl version 5 on Linux systems
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.
