Re: [deal.II] Trouble getting UMFPACK to work

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. On Wed, Feb 20, 2019 at 2:58 PM Jean-Paul Pelteret wrote: > Dear Darius, > > I just thought I’d ask

Re: [deal.II] Trouble getting UMFPACK to work

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

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. 在 2017年9月12日星期二 UTC+8下午8:08:14，Bruno Turcksin写道： > > 2017-09-11 23:45 GMT-04:00 曾元圆

Because I have already installed dealii, I don't quite understand what you mean by saying "configuring". Do you mean I need to recompile the whole dealii then it can know where to find lapack? LAPACK is a third party library right? so all I need to do is to tell the compiler where is the

Re: [deal.II] Trouble getting UMFPACK to work

Now suppose I have installed blas and lapack by execute command in terminal. Then the remaining part is UMPACK. Since "DEAL_II_WITH_UMFPACK = OFF" is apparently not expected. What I want to know is what I should do to change it to " DEAL_II_WITH_UMFPACK set up with bundled packages", which is

Re: [deal.II] Trouble getting UMFPACK to work

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! On Monday, September 4, 2017 at 7:29:01 PM UTC-4, Wolfgang Bangerth wrote: > > On 09/02/2017 08:54 AM, 曾元圆 wrote: > > have you solve this

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 installed openmpi. Since I could not find a way around this, I ended up

Timo, 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 deal.II/examples/step-1). I already have deal.II installed and compiled. I have been going through a few of the examples perfectly fine. Should I
