Problems with installing UMFPACK.

[solee]

Hi everyone!

I'm trying to conduct step-52 and I have some troubles while computing.

The error has occurred like this.

An error occurred in line <391> of file </home/choehh/DEAL.II/dealii-9.1.1/source/lac/sparse_direct.cc> in function

    void dealii::SparseDirectUMFPACK::factorize(const Matrix&) [with Matrix = dealii::SparseMatrix<double>]

The violated condition was: 

    false

Additional information: 

    To call this function you need UMFPACK, but you configured deal.II without passing the necessary switch to 'cmake'. Please consult the installation instructions in doc/readme.html.

So, I read README and installed LAPACK . After installed, I would like to change -DDEAL_II_WITH_UMFPACK=OFF to ON but it won't.

Therefore, I've tried to utilize another way via group user's method  "cmake -DDEAL_II_-DCMAKE_INATALL_PREFIX=/.... /dealii-9.1.1". But these message came out.

What does DEAL_II_WITH_UMFPACK set up with bundled packages (forced) mean?

Please help me....I need your help sincerely!!

I'm really looking forward of your replies. Thanks a lot!

That won't work. You need to reconfigure deal.II and recompile it.

It means that deal.II has been configured with UMFPACK and that it was forced to use the bundled package. So it won't look for another version that you may have on your computer. That is perfectly fine. However, you still need to recompile deal.II

Best,
