| 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. | |

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. | |

26 | =head2 Experimental Support for Sun Studio Compilers for Linux OS |
| 27 | ||
| f858446f | 28 | Sun Microsystems has released a port of their Sun Studio compilers for |
| 9ffb8441 SF |
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: | |
| 6452e86c SP |
34 | |
| 35 | LDLOADLIBS=-lc make | |
| 36 | ||
| 9ffb8441 | 37 | C<LDLOADLIBS> is an environment variable used by the linker to link |
| 6452e86c SP |
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. | |
