Hi folks, Anyway, I have a main development system which is P4 based (without EM64T) and a dozen diskless Athlon 64's. I'd like to be able to compile kernel's, etc for the Athlons in x86_64 bit mode. Any idea how to arrange this? I've recompiled the src.rpm for binutils (added a single line "CARGS=--enable-targets=x86_64-linux" to the specfile) and "as --64" doesn't bork anymore, so I'm assuming I've got that right... I'm assuming I next have to do something to gcc? Haven't figured this out yet... Anything else needed? Holiday cheers, MaZe.
