------- Comment #2 from burnus at gcc dot gnu dot org 2009-10-20 07:51 ------- Disclaimer: I do not know what ./configure does with regards to library search paths.
> --with-mpfr=/usr/local > /usr/lib/libmpfr.so.1: undefined symbol: __gmp_get_memory_functions Seemingly, the /usr/lib and not the /usr/local/lib version is used. Frankly, I do not know how exactly --with-mpfr works, but I think the path is only used for compiling and not for running the compiled programs. Thus when running "gfortran" (which happens when building the libgfortran library), the wrong shared library is picked up. Does setting the LD_LIBRARY_PATH help? I mean: if [ -z "$LD_LIBRARY_PATH" ]; then LD_LIBRARY_PATH=/usr/local/lib else LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH" fi export LD_LIBRARY_PATH At least in case of the finally installed version you need to set LD_LIBRARY_PATH - otherwise you have the same problem: The wrong library is picked up. Though, I am surprised that /usr/lib is used; I think most linux distributions set /etc/ld.so.conf such that /usr/local/lib comes before /usr/lib. If you have newly installed the GMP/MPFR in /usr/local/lib, maybe running ldconfig helps? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41760
