Not sure I understand. If I say 'mpi depends on mpe' - then the link line is:

-lhypre -lmpi -lmpe

But thats incorrect usage - and not what I want.. The correct usage is: -lhypre -lmpe -lmpi

The issue comes up with -llmpe - which traps MPI_xx functions - and does some logging - and then calls MPI_xx functions from -lmpi. i.e usage is:

-lhypre -llmpe -lmpe -lmpi

Right, but this MPE package is changing the MPI interface. All those other packages, like Hypre, depend on MPI. MPI depends on MPE, but the MPE module may modify the MPI lib to be '-lmpe -lmpi'. I do not see another way to do this. Matt

Matt,

Is it possible to specify package dependencies such that the

following happens:

...

[all mpipackages like -lhypre] [-lmpe] -lmpi

Currently I have: mpe: depends on mpi hypre: depends on mpi

And configure can do: -lmpe -lhypre -lmpi

But I want to say: mpe: depends on mpi, but before all other mpi packages.

...

From a library dependency POV, it is the other way around: MPI depends on MPE, but the dependency is optional.
