Hi,
I’ve tried installing ngsxfem in a million different ways now on my Silicon mac.
I’m now using virtual environments using micromamba (like conda), and install ngsolve successfully using pip install ngsolve.
However, when I then try to install ngsxfem by writing pip3 install xfem, I get the following cmake error message
CMake Error at CMakeLists.txt:74 (find_package):
Could not find a package configuration file provided by "NGSolve" with any
of the following names:
NGSolveConfig.cmake
ngsolve-config.cmake
Does anyone know how to fix this?
lets try installation #1.000.002:
pip3 install --pre xfem
with this I get xfem-2.1.2303.post64.dev0-cp312-cp312-macosx_10_15_universal2.whl installed
Thank you for your reply Joachim, unfortunately this gives me the same error message.
From
pip3 install --pre xfem
I get:

Uninstall all you netgen-mesher and ngsolve packages, and show us what you get (from the beginning up to the problem)

Attached, you find the complete output after uninstalling ngsolve using pip, and then redoing the installations.

there are only xfem binary packages for Apple Silicon for Python 3.11 and 3.12 (universal.whl), see xfem · PyPI
your options are
- swtich to Py 3.11 or 3.12
- ask the xfem developers for universal wheels also for elder Py versions
- compile yourself
Hi,
I created a clean virtual environment with no packages installed, and did the following:
- Install python3.12 using
micromamba install python=3.12.
- Install xfem by writing
pip3 install --pre xfem.
This succeeds with the output

However, if I enter python3 and type from xfem import *, I get the following error message, indicating that xfem was not installed for the ARM architecture. What am I doing wrong then?
>>> from xfem import *

The exact same thing happens if I try to do it with python3.11. I’m using macOS 14.4.1.
Hey,
We just updated the pip-packages for xfem and tried to support more Mac configurations. Please have another try.
Best,
Christoph
Hi,
Now I’m getting a segmentation fault instead:
