help accessing mgis.fenics installed through spack #75

Closed minamdar closed 2 years ago

minamdar commented 2 years ago

Hello, I am trying to install mgis via spack. Specifically, I want to use mgis.fenics libraries to run the demos created by J. Bleyer. To that end, I did the following.

1) Downloaded spack. Created and activated a new environment 'fenics-env' 2) Installed fenics in the environment 'fenics-env' using: spack install fenics 3) Installed 'mgis' in the same env as 2) using: spack install mgis

Now, while staying in the same env 'fenics-env', when I start the python console and type:

4) import dolfin as df

the libraries load just fine. However, when I type

5) import mgis.fenics as mf

I get an error that mgis library is not found.

When I search externally, I see that mgis libraries are installed in the opt/ folder of spack. Could you please help me? My understanding of such matters is at a bare minimum. I am using OSX-Catalina and apple clang-11.0.

Thank you. Mandar

Hi Mandar,

You have to specificy that you want the python bindings for mgis. Under Linux, this works like a charm:

$ spack install fenics tfel +python mgis +python
$ spack load fenics tfel mgis
$ python3 
Python 3.8.12 (default, Oct 28 2021, 15:21:40) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import mgis.fenics

On Mac Os, I did have some trouble due to the dependency to numpy which depends on blas and openblas did not compile on my box. Let me know if you have more success than I did.

Best, Thomas
