[mpich-discuss] pgf90-Error-Unknown switch: -pthread

[Kenneth Raffenetti]

Libtool is adding the -pthread flag because it exists in the 
"inherited_linker_flags" in libpmi.la. However, PGI clearly doesn't 
understand it. The libtool devs called this issue a bug when it was 
reported here:

http://lists.gnu.org/archive/html/libtool/2010-11/msg00034.html

You could either remove the flag from the /usr/lib/libpmi.la file, or 
use the workaround suggested by Gus Correa to finish your build.
