-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey
yeah i just started running into " so it either spits gobs of warnings or just plain fails. " lol I got intel compilers trying to twiddle with it all it would be really nice to see how it all compares :P. i would really love to get a sparc machine at somestage to test it i might be able to get access to one at work so i'll keep you guys updated on it anyways if i get sun compilers working in linux :P i am thinking i might remove gcc completly then see if sun works a little easier. - -Phil Monty Taylor wrote: > Philip Herron wrote: >> whoops forgot to reply to all :) >> >> Hey >> >> Thats pretty cool are you compiling all of them under gcc?
