I built a cross-dev environment sometime ago. Here's what I did: 0. got glibc-?.tar.gz from the usual places get binutils-?.tar.gz get egcs-?.tar.gz 1. Built and installed binutils 2. Began with the egcs configure --prefix=/usr/local \ --build=i686-pc-linux-gnu \ --host=i686-pc-linux-gnu \ --target=powerpc-unknown-linux-gnu make LANGUAGES=c make -k /* make fails, trying to build libgcc.a */ make -k LANGUAGES=c install /* now we have a compiler, which compiles. We can't link yet, so * we can't create shared libs or executables, but we _can_ create * static glibc */ 3. Began with glibc configure --prefix=/usr/local \ --build=i686-pc-linux-gnu \ --host=powerpc-unknown-linux-gnu \ --enable-add-ons=crypt,linuxthreads \ --disable-profile make -k /* build fails when trying to link some execitables * and some shared libs */ make -k install install_root=whatever /* now we have enough headers and static librararies to complete * the build of gcc */ 4. Back to egcs make make install /* no errors at this point, now we have complete gcc */ 5. Back to glibc make make install install_root=whatever /* no errors anymore */ That's all. Don't rely on the exact parameters to configure, I got them from memory. Regards, -velco ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
