I first installed gcc 4.5.0 on my Powerpc dual 970 machine with no configuration options. That was successful, but the long long feature was not enabled. Then I re-installed gcc 4.5.0 with this gcc v output:
Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/powerpc-apple-darwin9.8.0/4.5.0/l to-wrapper Target: powerpc-apple-darwin9.8.0 Configured with: ../gcc-4.5.0/configure --with-cpu-64=970 --with-tune-64=970 --enable-long-long --enable-languages=c,c++,fortran,java Thread model: posix gcc version 4.5.0 (GCC) The output from config.guess: powerpc-apple-darwin9.8.0 I also let GCC install gmp 4.3.2, mpc 0.8.1 and mpfr-2.3.1 (patched) I had previously installed gmp 5.0.1 with the other two listed above. When I ran configure for gcc 4.5.0, it stopped and told me I had the wrong version of gmp/mpc/mpfr installed (it never said which one). So I stepped back to the previous version of GMP, unstalled all three from /usr/local/include/ and /usr/local/lib/, then had GCC install them; I notice it did not use the same directories. How do I configure GMP 5.0.1 or any of the others to upgrade the installed versions? Regarding your installation notes for powerpc-darwin, I¹d already installed Xcode on my machine. Definitely needed on a mac to install anything that's not mac ready. I had no luck installing ppl 0.10.2 It kept telling me I had the wrong version of gmp for both of the versions I tried, even when I tried to have gcc install it. FYI, I¹ll only have this machine for another six months or so before it¹s upgraded. -- William L.
