Hi Pals:
I find on rpm.pbone rpm packages of gpc20070904 for 64 and 32 bits. I test it on Fedora 20 and works. I realize that this version of Fedora have the gcc 4.8 installed on it, thats have me to think that this is not used to compile gpc and make the rpm package.
I will test on newest fedora releases to know if they still work. Meanwhile I will learn read about GCC and his tools to try to make a compile on newest vesions on GCC.
Best Regards
Oscar Flor
