Tobias Burnus <burnus at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |burnus at gcc dot gnu.org --- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-08-30 16:35:41 UTC --- Most of the time it indicates that your MPFR or GMP libary is wrongly installed, which is not a GCC problem. a) How do you configure GCC? b) Check for the actual error in /home/silvio/Downloads/gcc-4.3.4/x86_64-unknown-linux-gnu/libgfortran/config.log - or attach it as suggested. * * * > I am working on Fedora 15 64-bit. Is there a special reason that you want to build GCC 4.3.4 instead of using the GCC/gfortran which is shipped with Fedora 15? (Namely, GCC 4.6.x.) By the way, for x86_64-unknown-linux-gnu there are unofficial builds available at http://gcc.gnu.org/wiki/GFortranBinaries - the nightly 4.7 version but also snapshot builds for 4.3 to 4.7.
