That's correct and necessary. > This sounds a bit odd as I'm not building a compiler that's going to > run on a m68k-linux but a compiler that going to build for a > m68k-linux target. Sure; but you need to build some target object code as part of the compiler, too -- see /usr/lib/gcc/<host triplet>/<compiler version>/*; that's code that gets linked into any binary as part of the necessary ELF magic. > My question here is: Is tpkg-make (the tool that > sets up the build stage for a cross copmiler) missconfiguring gcc or > should I patch the control.m4 file to remove the -m68k-cross part or > should I first build the libc6-dev-m68k-cross package? Yes, you first need to build and install the libc6-dev-m68k-cross package with dpkg-cross. > 2) If I patch the control file to not depend on libc6-dev-m68k-cross > and continue the build process, then I get quite far.
