I built binutils with --target=m68k-uclinux. Make sure you match any prefix option with how you intend to install gcc later. > Then configured gcc just like I did with the older version that compiled > just fine. > > ./configure --target=m68k-uclinux --prefix=/opt/embedded > --enable-languages=c I use this to configure gcc: --target=m68k-uclinux --with-headers=/usr/m68k-uclinux/include --enable-multilib --disable-shared --enable-languages=c I am using /usr/m68k-uclinux as my cross compiler area (It fits there since I am actually generating debian packages for installation). Hence no --prefix in my case. Of course I did have to temporarily build a gcc without library or header support and install it to build uclibc to get the headers before building gcc fully. > make You MUST use a builddir when building gcc 4.x. So for example: mkdir m68k-uclinux cd m68k-uclinux ../configure --target=m68k-uclinux --with-headers=/usr/m68k-uclinux/include --enable-multilib --disable-shared --enable-languages=c make Trying to build in the gcc source dir always fails.
