Hi Martin,

first of all I would like to ask you what is the reason for compiling
getfem yourself instead of using the deb packages from debian repos? I
suppose you want to enable parallelization which is not included in the
deb packages, right?

The configure flags used for the creation of deb packages are the
following:

configure_flags= $(CROSS) --prefix=/usr \
                --enable-boost --enable-shared --with-pic \
                --enable-python --enable-muparser \
                --disable-matlab --disable-superlu \
                --with-mumps="-lsmumps_seq -ldmumps_seq -lcmumps_seq 
-lzmumps_seq
-lpord_seq"

This may help you.

Regarding the problem with mumps, I would like to ask you which version
of getfem are you trying to compile? After the last release I think I
have made changes in the configure script, removing some redundant mumps
checks. Could you try the latest version from the svn repository?

With respect to the compilation of your code, you need to specify the
compilation/linking flag -lgetfem and possibly something like
-I/.....include..getfem..headers..path
