Hi, I am confused about object sizes (32-bit vs 64-bit). I am trying to build gcc 4.1.2 from a source RPM (Yellowdog Linux 6.1 I think) on a 64-bit powerpc machine (G5). It is not working. I think the source rpm only builds correctly on a 32-bit machine. It keeps trying to find stuff in .../32/... that is not there. Also, before I started hacking on the spec file it was building the compiler as a 64-bit program. Now it can't seem to find libsupc++.a. That is not correct, right? xgcc also defaulted to building things in 64-bit (with no -m64 option). Generally that is wrong too? i) Is the compiler ever built as a 64-bit program itself? ii) "Normally" the compiler should default to producing 32-bit objects, right (irregardless of what size machine the compiler itself was built on)? iii) What is the difference between directories ".../64/..." and ".../lib64/..."? Is it a convention? Should I see one or the other? Thanks!
