I can try it, but last time I tried it wasn't working. Note that here: http://gcc.gnu.org/install/specific.html#x-ibm-aix it is written: Because GCC on AIX is built as a 32-bit executable by default, (although it can generate 64-bit programs) the GMP and MPFR libraries required by gfortran must be 32-bit libraries. Building GMP and MPFR as static archive libraries works better than shared libraries. My impression is that if you were right, this wouldn't be mentioned. On the other hand it seems that not only gfortran requires them, so maybe this whole part is wrong. > Are you installing dynamic libraries for gmp, mpfr and mpc?

No, as in quoted text above: "Building GMP and MPFR as static archive libraries works better than shared libraries". -- Jędrzej Dudkiewicz I really hate this damn machine, I wish that they would sell it. It never does just what I want, but only what I tell it.
