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
