linking to optimized libraries

Hi Steven,

I installed MPB on RHEL 4 for AMD64 OPTERON (dual core) with the standard BLAS
and LAPACK libraries. Now I would like to use the ACML library (BLAS and LAPACK
routines optimized for AMD OPTERON).
How can I link to these libraries even if they are not called liblapack and
libblas?

I tried already to set a symbolic link named liblapack.so.3 to the ACML library
libacml.so located in /opt/acml3.5.0/gfortran64_mp/lib and got the following
error message from running $ mpb-mpi tri-rods.ctl >& tri-rods.out

mpb-mpi: symbol lookup error: /opt/acml3.5.0/gfortran64_mp/lib/liblapack.so.3:
undefined symbol: _gfortran_copy_string

Does this mean that MPB has a problem with the link or is this a problem of the
library?

Thanks in advance

Christine
