Dear Wenguo, It looks like you’re linking deal.II, built as a shared library, against LAPACK, built as a static library. As the error message suggests, you’ll need to build LAPACK with the -fPIC flag in order to do this. As suggested here (https://stackoverflow.com/questions/18828730/lapack-linking-error-recompile-with-fpic <https://stackoverflow.com/questions/18828730/lapack-linking-error-recompile-with-fpic>) you should make the following changes to make.inc when building LAPACK:
FORTRAN = gfortran -m64 -fPIC OPTS = -O2 -m64 -fPIC DRVOPTS = $(OPTS) NOOPT = -O0 -m64 -fPIC LOADER = gfortran -m64 -fPIC I hope that this helps you resolve your issue.
