Looks like you are building .lo files in your application because you are using libmesh's Make.common. So you'll have to use libtool to link it as well. i.e. # Production rules: how to make the target - depends on library configuration $(notdir $(target)): $(objects) @echo "Linking "$@"..." @$(libmesh_CXX) $(libmesh_CXXFLAGS) $(objects) -o $@ $(libmesh_LIBS) $(libmesh_LDFLAGS) $(EXTERNAL_FLAGS) becomes # Production rules: how to make the target - depends on library configuration $(notdir $(target)): $(objects) @echo "Linking "$@"..." @$(libmesh_LIBTOOL) --tag=CXX $(LIBTOOLFLAGS) --mode=link --quiet $(libmesh_CXX) $(libmesh_CXXFLAGS) $(objects) -o $@ $(libmesh_LIBS) $(libmesh_LDFLAGS) $(EXTERNAL_FLAGS) -- John ------------------------------------------------------------------------------ Master Java SE, Java EE, Eclipse, Spring, Hibernate, JavaScript, jQuery and much more.
