Re: Compilation problem with mumps

[Konstantinos Poulios]

Dear Pierre

This is how I compile sequential getfem on our cluster (running some version of Scientific Linux):

I put all dependencies (symbolic links actually) into two folders:

/some_path_with_dependencies/lib
/some_path_with_dependencies/include

then I configure getfem with

./configure --prefix=/some_installation_path/getfemseq BLAS_LIBS=-L/some_path_with_dependencies/lib -lopenblas -lpthread CPPFLAGS=-I/some_path_with_dependencies/include LDFLAGS=-L/some_path_with_dependencies/deps/lib LIBS="-lmumps_common -lpord -lmpiseq -lmetis -lesmumps -lscotch -lscotcherr -lpthread -lgfortran" --with-optimization=-O2 --with-pic --disable-matlab --enable-python --enable-mumps

My "include" and "lib" dependencies folders contain:

This is the minimal amount of files that GetFEM links to. Depending on how you compile mumps, you might get slightly different dependencies, but I think you get the idea.

If you are still stuck after this, just let me know and I can tell you how to debug the configure error more systematically.

Best regards

Kostas

Hi, Pierre. Disclaimer: I haven't been able to compile the test suite
correctly (take my advice with reserves).

The sequential libraries of MUMPS usually have _seq before the .o . I
can imagine that you already checked that you have the right libraries.
By the looks of it, you are using the parallel version, but I don't dare
to draw such conclusion. This comes from the configure file, and you
might want to try it:

     "-lsmumps_seq -ldmumps_seq -lcmumps_seq -lzmumps_seq"

I remember that I was able to hijack the library files with a variable
(MUMPS_LIBS?), but I am sure that the developers will have much better
advice than this.

Bonne chance!
