[mpich-discuss] Adding libraries to the mpicc wrapper

User libraries are prioritized over MPICH and other libraries when passed to mpicc.

So mpicc foo.c -lmylibrary will result in:

gcc foo.c -lmylibrary -lmpich

Is that what you want to do?  If then, I’d recommend Jeff’s approach of creating a wrapper mpicc.new script that internally calls mpicc.

So far to make the use of the library transparent when compiling a program, I added the library at line 226 of the mpicc wrapper (mpilibs=" -lmpich -lmylibrary"). I'd like to know if there is a "cleaner" way of adding it: mpicc being generated from a template, there should be a way to simply set a variable somewhere for that, shouldn't it? How is it done for other ADIO backends?
