(cached) GNU/Linux ld.so checking how to hardcode library paths into programs... immediate checking whether the GNU Fortran compiler is working... no configure: error: GNU Fortran is not working; please report a bug in http://gcc.gnu.org/bugzilla, attaching /wk5/WJ/tmp/gcc-4.8.0/x86_64-unknown-linux-gnu/libgfortran/config.log make[1]: *** [configure-target-libgfortran] Error 1 make[1]: Leaving directory `/wk5/WJ/tmp/gcc-4.8.0' make: *** [all] Error 2 the config.log is also attached.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68268 --- Comment #2 from isearcher at 126 dot com --- i download GCC installation file and tar it at /wk5/WJ/tmp. And i configure GCC at /wk5/WJ/gcc. ./configure --prefix=/wk5/WJ/gcc -enable-threads=posix -disable-checking -disable-multilib -enable-languages=c,c++ --with-gmp=/wk5/WJ/gmp-4.3.2 --with-mpfr=/wk5/WJ/mpfr-2.4.2 --with-mpc=/wk5/WJ/mpc-0.8.1 i don't think there is something wrong with the srcdir and objdir. As i am working on a linux server, and can't get the root authority, i make the above choice.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68268 --- 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?
