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> 2011-06-16 13:39:34 UTC --- In 95% of the cases one sees this error, there is a problem with GMP or MPFR. That seems to be also the case here: /home/e.ab/software/src/gcc-4.5.3-build/./gcc/f951: symbol lookup error: /usr/local/lib/libmpfr.so.1: undefined symbol: __gmp_get_memory_functions Can you check that your GMP and MPFR are compatible, that they are in the library search path, etc.?
