Dear GetFEM++ community,

I am a brand new GetFEM++ user, and not yet a full geek, so let me excuse myself in advance for the trivial questions.

First of all, compilation issues.

When configuring with "--with-pic" (my system is Kubuntu x86_64), everything seems to be fine. However, in "config.log" I see "checking for library containing xmumps_c [...] result: no" for = {s, d, c, z}; then I see "checking for xmumps_c in -lxmumps [...] result: no"; but then I see "checking xmumps_c.h usability [...] result: yes", "checking xmumps_c.h presence [...] result: yes" and "checking for xmumps_c.h [...] result: yes", so I am wondering if MUMPS works or not.

When configuring with "--with-pic --enable-mumps", I received the following error: "configure: error: The function smumps_c couldn't be found in the provided MUMPS libraries.". I tried to use "--with-mumps" and "--with-mumps-include-dir" but without success. MUMPS has been installed through debian repositories, so I am wondering if I need to compile it from sources.

When configuring with "--with-pic --enable-paralevel=2", I received the following error: "configure: error: header file mpi.h not found.". Once again, MPI has been installed through debian repositories, but maybe it is not the correct way.

Now, computation issues.

Suppose the code has been configured with "--with-pic" and compiled. Suppose I want to start from laplacian.cc and modify it to adapt it to my problem. If I go to tests, I can run "make laplacian" and then "./laplacian laplacian.param" and everything works perfectly. However, when I move laplacian.cc and laplacian.param to my own directory, I do not manage to compile neither to link the code properly. Is there a simple way to do that?

Many thanks in advance for your precious help.
Martin.
