If all you want is a cross compiler to make a kernel why not try this procedure ? Tested with : gcc-3.4.2 binutils-2.15.90.0.3 dietlibc-0.28 or dietlibc cvs 1 untar all sources 2 binutils: ./configure --prefix=/usr/local/powerpc-linux --target=powerpc-linux make make install 3 gcc: ./configure --prefix=/usr/local/powerpc-linux --target=powerpc-linux --with-ecos --disable-nls --enable-threads=posix --disable-shared --enable-languages=c --with-headers=../dietlibc/include make make install There might be a little error in gcc/unwind-dw2-fde-glibc.c and gcc/unwind-dw2-fde.h I can't remember the exact errors in those two files, but, hopefully those should be easy enough to fix. Once you work around the slight inconsistency between dietlibc & gcc in those two files, and make install, you should have a full toolchain in /usr/local/powerpc-linux I had been thinking about making a small script for kernel people such as yourself, who wanted just a toolchain for kernel cross compiles. Maybe I'll do that. But, in any case, the above procedure gives me a 3.4.2 which is quite happy to compile a 2.4.28-rc3 (though I haven't tried out the denx 2.4.25... but, I can't see why that would fail). Hope this helps. -- Bryan
