I just checked the size of insn-attrtab.c, it's actually 1.4GB! :S >> My computer is a PowerMac G5, I'm running Mac OS X 10.5.8; I have >> nothing 'newer', so I can't try it on an intel based machine. >> I use gcc-4.2 (which does _not_ work the same as gcc-4.2 on intel, >> so it might work fine on intel, even though it fails on PowerPC). >> >> I can compile gcc 4.3.x up to 4.5.x (all inclusive), but 4.6.x is >> giving me trouble. >> Does anyone know how to get me going ? > > Since the problem may be in the GCC 4.2 you got from Apple, have you > tried using a different compiler to build 4.6? I would try using GCC > 4.5, which you can build successfully. I forgot to mention that this is a cross-compiler I'm building for the ARM target on my Mac. On my Mac, I have gcc-4.0 and gcc-4.2. gcc builds fine for ARM, but I do not yet know if it builds for Mac/PowerPC. 2 questions: 1: Wouldn't gcc-4.5 [by default, that is] have the same malloc-problem as 4.2 ? 2: Doesn't Apple compile gcc in a special way, so that it differs from a standard ./configure && make install ? Anyway, I'm trying (once again) to compile gcc for Mac/PowerPC Love, Jens
