Yes. At configure time, either set the environment variables CC, CXX, and FC to specify the PGI C, C++, and Fortran compilers (respectively) or use the –with-cc=, –with- cxx, and –with-fc flags at configure time. Due to a bug in Libtool, it may not be possible to build LAM with shared libraries with some Portland Group compilers. However, it is possible to build static libraries. In the past, there have been small issues with LAM/MPI, Linux, and the PGI compilers. In all cases, the problem was traced to bugs in the Linux system header files. The latest such problem was with Red Hat 7.1. If you are using Red Hat 7.1, you will want to apply the Red Hat provided updates to glibc to fix some minor system header file issues.
