Hi, crossgcc won't build on openSUSE 12.1 x86_64 because the gmp libraries end up in xgcc/lib64/ (as designed) but mpfr expects them to be in xgcc/lib/ (why?). Workaround is to add a symlink xgcc/lib -> xgcc/lib64 . autoconf is claimed to be needed to build binutils (at least according to buildgcc), but buildgcc ignores a missing autoconf and proceeds anyway. That's not a problem, binutils builds just fine. I wanted to give other openSUSE 12.1 users a heads-up and make the solution searchable via the mailing list archive.
