Support Compilers Older Than GCC v4.7? #75

Open wbraswell opened 7 years ago

wbraswell commented 7 years ago

@eserte One or more of your FreeBSD machines on CPAN Testers has an old version of GCC v4.2, and RPerl requires GCC v4.7 or newer.

gccversion='4.2.1 20070831 patched [FreeBSD]'

http://www.cpantesters.org/cpan/report/a6a0a588-d7ca-11e6-9ece-bdfa082fd90d

My goal is to reach 100% CPAN testers coverage.

Is it better for you to upgrade the GCC yourself, or is it better for me to create Alien::gcc which will rebuild a new GCC from source (which will add extra runtime)?

This machine (freebsd 9.2) has a gcc-4.8 package installed,additionally to the system's gcc.

$  gcc48 -v

@eserte How can we tell your system to use the gcc48 compiler, without changing RPerl for everyone else?
