Hello Jeff, I would like to continue this discussion. Corresponding changes in Clang are already in SVN and the feature should be released with the upcoming Clang 3.2. I tried to follow your advice about Fortran datatypes and updated the patch accordingly (attached). This patch is against OpenMPI 1.9. Please review. Is there any chance we can get a less invasive (header-only, without autotools magic for Fortran datatypes support) change in the OpenMPI 1.7? > Does clang link together with gfortran? I.e., does the following work: > > ./configure CC=clang CXX=clang++ FC=gfortran ... Seems like it works.
