When installing the latest version of Open MPI (Version 1.6.1) with PGI compilers (specifically 12.5), the installation fails.

The following configure option are set:


CC=pgcc CXX=pgcpp F77=pgf77 FC=pgf90 ./configure --prefix=/usr/local/${BASE}-pgi --with-openib --with-tm=/usr/local/torque/latest --enable-static --enable-share


For Torque "latest" in this context is only 2.4.17, however that shouldn't be the issue. The make fails as follows:


make[6]: Leaving directory `/usr/local/src/OPENMPI/openmpi-1.6.1/ompi/contrib/vt/vt/tools/vtunify'

... and so it goes. It is fairly clear what the problem is, and thank to Andrew Chalmers for the following work around.

In /usr/local/pgi/linux86-64/12.5/include/CC/stl/_threads.h (or similar) line 138 make the following modifications.
