--- Comment #8 from Vittorio Zecca <zeccav at gmail dot com> 2011-09-14 08:23:39 UTC --- gfortran 4.7.0 fixes this one. However, sometimes I get the following: /home/vitti/gcc-4.7/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/f951: symbol lookup error: /home/vitti/gcc-4.7/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/f951: undefined symbol: mpfr_get_z_exp Never got this one, I have mpfr-3.0.0-4 How can I fix it?
