Mahmood,
did you build Open MPI as a static only library ?
i guess the -ldl position is wrong. your link command line should be
mpifort -O3 -o xCbtest blacstest.o btprim.o tools.o Cbt.o
../../libscalapack.a -ldl
you can manually
mpifort -O3 -o xCbtest --showme blacstest.o btprim.o tools.o Cbt.o
../../libscalapack.a -ldl
it should show -ldl is added *after* -lopen-pal
Cheers,
Gilles

Sounds to me like you're missing a -ldl linker flag.

Hi
I am building scalapack with mpicc and mpifort, however this
is the error I get:

As I grep "dlopen", some OMPI binary files match. Any idea
about that?
