Hello. I’ve built the dolfinx c++ core from source and I am trying to install the python interface with pip install .

haydel@Delta-XPS-15-9500:~/FEniCSx/dolfinx/cpp/build$ make install

Don't forget to update your environment variables. This can be done
easily using the helper file 'dolfinx.conf' which sets the appropriate
variables (for users of the Bash shell).

To update your environment variables, run the following command:

Is there an easy fix for this? seems like I just need to point the setup.py to the correct directory, but I am not quite sure the best way to go about this without editing the file.

my environment vars are :

I know that I can use the spack package manager or docker image, but I would like to get this working if possible.

There is a DOLFINXConfig.cmake inside /home/haydel/FEniCSx/dolfinx/cpp/build/lib/cmake/dolfinx/
should I be using that one instead?

the dolfinx/cmake_install.cmake is putting those files here "$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/lib/cmake/dolfinx/DOLFINXTargets.cmake"
yet the config.cmake tries to include them from here:
dolfinx/DOLFINXConfig.cmake: include("${CMAKE_CURRENT_LIST_DIR}/DOLFINXTargets.cmake")

I went ahead and changed the line include("${CMAKE_CURRENT_LIST_DIR}/DOLFINXTargets.cmake")
to point to this one instead /home/haydel/FEniCSx/dolfinx/cpp/build/lib/cmake/dolfinx/DOLFINXTargets.cmake/DOLFINXTargets.cmake and the build was able to complete.

But I unable to get a working finished product.
with errors like:

In all honesty, I haven’t read the whole text, but PKGBUILD recipes are kind of a clear way on compilation instructions. If you want, you can check:
https://aur.archlinux.org/packages/fenics-basix-git
https://aur.archlinux.org/packages/dolfinx

Note that every line with a depends relates to another package which will be needed for your installation, and the names are definitely not consistent across distributions (flavours of Linux)

depends=(boost xsimd python-fenics-ffcx hdf5-openmpi petsc parmetis pugixml)

Another disclaimer: I am a new user :slight_smile: . Good luck.
