I'm pretty sure you can build the C compiler only without the runtime libs. You can then build the runtime libs with this compiler. Once this is done you should be able to build all the other GCC components such as C++, fortran, etc. If you preinstall some runtime libs from a powerpc system, then you can build all the GCC components at once, then rebuild the runtime libs. The preinstalled runtime libs don't even have to be the ones for your target system, just as long as the GCC can find some runtime libs. eg. I used the yellowdog linux glibc libraries which were pointed out to me by Kai Ruottu. Here are his instructions. http://www.yellowdoglinux.com/ ftp://rpmfind.net/linux/yellowdog/champion-1.0/ppc/RedHat/RPMS/ - glibc-2.1-1a.ppc.rpm - glibc-devel-2.1-1a.ppc.rpm Use rpm and cpio to extract the files into a temporary directory. $ rpm2cpio glibc-2.1-1a.ppc.rpm > glibc-2.1-1a.ppc.cpio $ rpm2cpio glibc-devel-2.1-1a.ppc.rpm > glibc-devel-2.1-1a.ppc.cpio $ cpio -iBdmv < glibc-2.1-1a.ppc.rpm $ cpio -iBdmv < glibc-devel-2.1-1a.ppc.rpm After copying all the "lib/..." stuff into "usr/lib" and fixing the symbolic links in "usr/lib" (those pointing to ../../lib) to point to the files in the same directory, move the stuff from "usr/lib" and "usr/include" to $prefix/$target/lib and $prefix/$target/lib directories. Probably need to fix the "-dynamic-linker" statement in the specs file ($prefix/lib/gcc-lib/$target/$egcs-version/specs) to be "-dynamic-linker $prefix/$target/lib/ld.so.1". Also need to edit $prefix/$target/lib/libc.so. Change /usr/lib to $prefix/$target/lib. Cheers, Brendan Simon. ------ Want more information?
