--- Comment #3 from isearcher at 126 dot com --- Sorry, the configure command is like this (fortran is added): ./configure --prefix=/wk5/WJ/gcc -enable-threads=posix -disable-checking -disable-multilib -enable-languages=c,fortran --with-gmp=/wk5/WJ/gmp-4.3.2 --with-mpfr=/wk5/WJ/mpfr-2.4.2 --with-mpc=/wk5/WJ/mpc-0.8.1 By the way, should i download the gfortran installation files additionally and install gfortran in this way?
