Hello, I am trying to build MPICH2 with PGI compilers (15.1) and -with-device=ch3:nemesis:ib and I am getting errors during the compilation. Here's how I configure MPICH: setenv CC pgcc setenv CXX pgCC setenv FC pgf90 setenv F77 pgf90 setenv FC pgf90 setenv FFLAGS "-tp=nehalem-64" setenv FCFLAGS "-tp=nehalem-64" setenv CFLAGS "-tp=nehalem-64" setenv CXXFLAGS "-tp=nehalem-64" setenv LDFLAGS "-tp=nehalem-64" ../../../srcdir/mpich/3.1.4/configure --prefix=/uufs/chpc.utah.edu/sys/installdir/mpich/3.1.4p --enable-romio --with-file-system=nfs+ufs --with-mpe -with-device=ch3:nemesis:ib --enable-fast=all --enable-threads=runtime There are multiple errors like: PGC-S-0060-immed_len is not a member of this struct or union (../../../srcdir/mpich/3.1.4/src/mpid/ch3/channels/nemesis/netmod/ib/ib_poll.c: 1847) Before I spam the list with more details, I'd like to first ask if anyone has experience with building MPICH with PGI and IB device, or if I am doing something wrong with the configuration. Note that MPICH builds fine with PGI and tcp and also the IB builds fine with our other supported compilers (Intel and GNU).
