Re: Problems with GCC 3.0.1 for m68k-coff

I had a similar problem with my most recent buld attempt. I was previously
using egcs 1.2 and have been trying to rebuild the m68k-coff over the past 3
years - unsuccessfully.

Using GCC 3.0 I followed the same faq and built binutils and the core gcc
successfully. I had trouble building newlib (see notes below) but eventually
got through it. After getting the same error as you with the full gcc build
I went and drank some good wine and started the GCC build from scratch in a
new directory tree later on. The solution was either the wine or a new build
directory. I recommend trying both!
i.e. initial gcc build to use for building newlib was /build/build-gcc
whereas the final build was done in /build/build-gcc-full.

The other problem I had was that m68k-coff-gcc built kept crashing for
certain library files in newlib, fortran libraries and others. I worked
around this problem by performing a "make -i all" and then manually
compiling the ones that failed without the -O2. Hence optimisation was
causing a problem. Excerpts of errors below.
