mpich2-1.4.1 is almost ten years old. You should try something recent if you want MPICH help. Otherwise, you should consult the GCC toolchain folks, although they have seen this before and it appears to be in an unresolved state ( https://gcc.gnu.org/bugzilla/show_bug.cgi?format=multiple&id=49986).

Hello, all.

I install MPICH on IBM AIX and try to compile pi3f90.f90 in the example, but I get an error not finding emutls_get_address, muldc3, mulsc3. There was a similar problem in the previous case, but it's not clear how it was resolved, so I'm sending you an email. Old thread: https://lists.mcs.anl.gov/pipermail/mpich-discuss/2012-August/012920.html I know that IBM AIX is an OS not supported, but if you have any suggestions, we ask for a reply.

Best Regards, Kihang
