Hi,
Maybe you should check this web-page, I think this may help you in deed.
wiki.opentelemac.org/doku.php?id=installation_on_linux
In fact, if the MPI is not required as you said, to use the fundamental function of TELEMAC, you only need python/numpy/gfortran/HDF5/MED/SciPy/Matplotlib
Then you should rewrite your cfg file and pysource file. The basic one of cfg file could be like this:
cmd_obj: gfortran -c -cpp -fPIC -O2 -fconvert=big-endian -frecord-marker=4 -DHAVE_VTK <mods> <incs> <f95name>
cmd_lib: ar cru <libname> <objs>
cmd_exe: gfortran -fPIC -fconvert=big-endian -frecord-marker=4 -lpthread -lm -o <exename> <objs> <libs>
Take a look at the installation wiki first, that helps you.
Regards,
Sorrymaker
