GCC bugzilla is not a user support forum. Post to gcc-help with questions of this nature. The answer to your question lies in the ldconfig documentation.

And gfortran is made. > The problem is solved. thanks for the advice. You're welcome! Further advice, 4.8.0 is quite old and unsupported: you should go to at least 4.9.3 or better 5.2. Your gmp, mpfr and mpc libs are also old. I am using GMP version 6.0.0, MPFR version 3.1.2, MPC version 1.0.3.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68268 --- Comment #5 from isearcher at 126 dot com --- Hello! I create a build directory, cd to it, and execute "sources_dir/./configure ..." like this : /wk5/WJ/tmp/gcc-4.8.0/configure --prefix=/wk5/WJ/gcc -enable-threads=posix -disable-checking -disable-multilib -enable-languages=c,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 But there is a new error: make[2]: Entering directory `/wk5/WJ/gcc' make[3]: Entering directory `/wk5/WJ/gcc' rm -f stage_current make[3]: Leaving directory `/wk5/WJ/gcc' Comparing stages 2 and 3 warning: gcc/cc1plus-checksum.o differs warning: gcc/cc1-checksum.o differs Bootstrap comparison failure! gcc/plugin.o differs gcc/gcc.o differs make[2]: *** [compare] Error 1 make[2]: Leaving directory `/wk5/WJ/gcc' make[1]: *** [stage3-bubble] Error 2 make[1]: Leaving directory `/wk5/WJ/gcc' make: *** [all] Error 2 thanks.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68268 --- Comment #4 from Dominique d'Humieres --- Executing "./configure ..." means you are bootstrapping in the sources directory which is not supported according the manual. You must create a build directory, cd to it, and execute "sources_dir/./configure ..." from it, then "make".

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?

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.
