Dear Jean-Paul,
Yes, I was able to solve that problem. I installed LAPACK using the
command and later I compiled the entire deal.II library. Thanks for the
help.
Regards,
Darius Barreto.

Dear Darius,
I just thought I’d ask whether you were able to solve your problem?

Dear Darius,
Your installation of deal.II has not been compiled with UMFPACK supplied as an
external library. The bundled version has also not been built, likely because
you do not have the required dependencies installed. I believe that you need to
have LAPACK installed for it to work, so you

No you don't. You can use
If I want to run all the 57 steps, should I install all the mentioned
libraries? How can I know in advance which library I may need? Perhaps now
I don't need PETSc, but maybe someday in the future I will need.

Every time you add a new library you need to *reconfigure* and recompile
deal. Now if you want to use PETSc and
Thank you very much! So you mean every time I want to use another library,
I have to recompile and reinstall dealii again?

Because I have already installed dealii, I don't quite understand what you

Now suppose I have installed blas and lapack by execute command in
terminal. Then the remaining part is UMPACK. Since "DEAL_II_WITH_UMFPACK =

change it to " DEAL_II_WITH_UMFPACK set up with bundled packages", which

No -- deal.II has its own copy of UMFPACK. So, whenever deal.II can find
BLAS and LAPACK, it uses its own copy of UMFPACK. (It uses a copy of
UMFPACK if one is found on your system, but because it has its own

No UMFPACK has not been installed and lapack has not been found. You
need to install the dev version
Wolfgang, you are absolutely correct. My mistake was not having BLAS and
LAPACK, so it was unable to use UMFPACK. Thank you for all of your help!

I've actually deleted deal.II version 8.0.0 since last writing. I got
UMFPACK to work by installing BLAS and LAPACK, but then I kept getting an
error that it was unable to find the MPI library even though I had just

I still have yet to resolve the issue. As suggested, I have been trying to
delete deal.II and then reinstalling and configuring with
-DDEAL_II_WITH_UMFPACK=ON, but am still having trouble with it. I will

I do eventually plan on updating the code to the latest release.
I was doing the commands inside a folder in deal.II (similar to if I was in

have been going through a few of the examples perfectly fine. Should I

I would like to encourage you to update to the latest release. Many
things have changed and improved over the years. That probably also
includes handling of dependencies like UMFPACK.
