[mpich-discuss] mpich1 on OSX 10.6

[Reto Stöckli]

Dear MPICH discussion group

I am trying to compile mpich-1.2.7p1 on OSX 10.6 by using gcc 4.4 and  
alternatively gcc 4.2, but I fail with the following link error in the  
testing part of the compilation process (libraries have been built  
fine as I can see):

Testing that MPI applications can be linked...
make linktest
make overtake

This all worked fine in OSX 10.4 with gcc 4.2 using the same  
configuration settings. It seems to be that the linker now barks at  
symbols being present in both libmpich.a and libpmpich.a. Is it needed  
that during testing both libpmpich.a and libmpich.a are linked by  
default implicitly by using mpicc, or could we simply use libmpich.a?

Let me know if this error sounds familiar to you and if you have any  
suggestions for what to do here. I have successfully compiled and used  
mpich2 on 10.6, but I need mpich1 for compatibility testing as well.

Sincerely,
Reto
