Are your ATLAS libraries shared or static (i.e., are they libatlas.so or libatlas.a)? ldd(1) only lists the shared libraries that are linked. ATLAS is usually installed as static libraries. Does that module import? If so, then you have no problems. If not, then copy the message here. It should tell you one of the symbols that are missing. Note that libraries should be listed in the order in which they depend on each other. lapack depends on f77blas and cblas which both depend on atlas. lapack,f77blas,cblas,atlas -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco ------------------------------------------------------------------------- Using Tomcat but need to do more?
