As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file.

    1 If you read this file _as_is_, just ignore the funny characters you
    2 see.  It is written in the POD format (see pod/perlpod.pod) which is
    3 specifically designed to be readable as is.

    7 perllinux - Perl version 5 on Linux systems
    9 =head1 DESCRIPTION
   11 This document describes various features of Linux that will affect how Perl
   12 version 5 (hereafter just Perl) is compiled and/or runs.
   14 =head2 Deploying Perl on Linux
   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.
   23 Otherwise, perl should build fine on Linux using the mainstream compilers
   24 GCC and clang, while following the usual instructions.
   26 =head2 Experimental Support for Sun Studio Compilers for Linux OS
   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.
   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:
   35     LDLOADLIBS=-lc make
   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.
