[GAP Forum] GAP 3.4.4 on modern linux

[Ian McLoughlin]

Looks like you need to install an older version of gcc. maybe Fedora
provides one, though I doubt it!

Try downloading
gcc-3.2.tar.bz2<http://gcc-uk.internet.bs/old-releases/gcc-3/gcc-3.2.tar.bz2>from
http://gcc-uk.internet.bs/old-releases/gcc-3/.

I'd read...

http://gcc.gnu.org/faq.html#multiple,
http://www.mjmwired.net/linux/2005/11/15/using-alternate-compilers/ and
http://www.mjmwired.net/resources/mjm-fedora-gcc.html

before I'd continue from there in case I made a mess :). I always make a
mess!
