[mvapich-discuss] Missing make dependencies in 1.8 latest

[Craig Tierney]

I am trying to build mvapich2 1.8-latest with make -j12 (because I am tired of waiting while debugging
other problems).  However, when building this way, the make process fails because some dependencies
are not handled correctly.

In particular it is in src/bindings/f90 where using -j causes a problem.

------------

---------------

The error can vary, it depends on order of builds finishing.  In this case, the compile
of mpi_constants.f90 wasn't complete before mpi_base.f90 started.

I see that at least this patch is missing:

 	@if [ -n "" ] ; then \
 	    rm -f mpimod.pc mpimod.pcl ; \
 	    echo "mpimod.pc" > mpimod.pcl ; \

However, I cannot see why the dependencies are missing for the build of mpi.f90.  It looks like they are there:

$(MPIMOD).$(MOD): $(MPICONSTMOD).$(MOD) $(MPISIZEOFMOD).$(MOD) \
                  $(MPIBASEMOD).$(MOD) $(srcdir)/mpi.f90 mpifnoext.h

But they are not being honored for some reason.  Someone more experienced with gmake than I should be able to
figure this out.
