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
the uninterpreted source code file.
1 If you read this file _as_is_, just ignore the funny characters you

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.
