Note that sometimes one needs to install some 19extra system packages in order to be able to use CPAN frontends, and that 20messing with the system's perl is not always recommended. One can use 21L<perlbrew|https://perlbrew.pl/> to avoid such issues. 22 23Otherwise, perl should build fine on Linux using the mainstream compilers 24GCC and clang, while following the usual instructions. 25 26=head2 Experimental Support for Sun Studio Compilers for Linux OS 27 28Sun Microsystems has released a port of their Sun Studio compilers for 29Linux. As of May 2019, the last stable release took place on 2017, and one can 30buy support contracts for them. 31 32There are some special instructions for building Perl with Sun Studio on 33Linux. Following the normal C<Configure>, you have to run make as follows: 34 35 LDLOADLIBS=-lc make 36 37C<LDLOADLIBS> is an environment variable used by the linker to link 38C</ext> modules to glibc. Currently, that environment variable is not getting 39populated by a combination of C<Config> entries and C<ExtUtil::MakeMaker>. 40While there may be a bug somewhere in Perl's configuration or 41C<ExtUtil::MakeMaker> causing the problem, the most likely cause is an 42incomplete understanding of Sun Studio by this author. Further investigation 43is needed to get this working better. 44 45=head1 AUTHOR 46 47Steve Peters <steve@fisharerojo.org> 48 49Please report any errors, updates, or suggestions to 50L<https://github.com/Perl/perl5/issues>. 51 52
