Hi all,
I am encountered a weird thing (bug?) and I am having trouble to understand
it. Maybe someone has an idea:
I am trying to solve a simple elliptic problem (imagine some sort of a
simple Laplace problem for now) with pure Neumann BCs, say -\Delta u = f,
n\grad u = g. Now theory tells me

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
Hello everyone,
I am installing deal ii -9.0.1 using recommended commands. and something
went wrong, the error message is as follow:
has someone ever met this problem?
