Lining against correct version of libmkl_blacs_*.so

Dear folks,

I am about to build an MPI executable with ifort/mpif90, linking it to the MKL and the OpenMPI libs. I came to the point where a serious problem wrt. to linking with the correct version of the mkl_blacs library occurs. I. e., I try to link with the library libmkl_blacs_ilp64.so (one of the MKL libraries), but the ifort/mpif90 inserts an incorrect library symbol into the ELF object file of the executable:

    libmkl_blacs_ilp64.so => not found


How should I tell the ifort/mpif90 compiler to link with libmkl_blacs_openmpi_ilp64.so and not wirh libmkl_blacs_ilp64.so?

 

Thanks for your help

Sebastian
