[Getfem-users] compilation and computation issues

[Martin Genet]

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.
