I have had time to get back to this. The currently prebuilt .dmg is currently built for python3.8, but I am using python3.9 so instead I am trying to build from source.

I have cloned the ngsolve repo into /Users/alex/Documents/GitHub/ngsolve/ngsolve-source, and then am running the following code, one line at a time.

I get the following error "ld: in '/opt/homebrew/opt/llvm/lib/libunwind.dylib', building for macOS-x86_64 but attempting to link with file built for macOS-arm64" in "/Users/alex/Documents/GitHub/ngsolve/ngsolve-build/netgen/dependencies/src/project_tkdnd-stamp/project_tkdnd-build-err.log".

I have tried it without the "-DUSE_NATIVE_ARCH=ON", same issue.

Any help on what I should do to fix this?
Code:
export NGROOT=/Users/alex/Documents/GitHub/ngsolve mkdir $NGROOT/ngsolve-build cd $NGROOT/ngsolve-build cmake $NGROOT/ngsolve-src -DPYTHON_INCLUDE_DIR=$(python3 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") -DPYTHON_LIBRARY=$(python3 -c "import distutils.sysconfig as sysconfig; print(sysconfig.get_config_var('LIBDIR')+'/libpython3.9.dylib')") -DUSE_NATIVE_ARCH=ON make -j 8 make install export PYTHONPATH=$PYTHONPATH:/Applications/Netgen.app/Contents/Resources/lib/python3.9/site-packages:. export NETGENDIR=/Applications/Netgen.app/Contents/MacOS export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$NETGENDIR export DYLD_FRAMEWORK_PATH=$DYLD_FRAMEWORK_PATH:$NETGENDIR/../Frameworks export PATH=$NETGENDIR:$PATH

Hi Alex,

could you attach ngsolve-buid/netgen/CMakeCache.txt ?
I suspect that you are mixing compilers here for some reason ("ld: in '/opt/homebrew/opt/llvm/lib/libunwind.dylib', why not using the system toolchain?)

Best,
Matthias

Hi Matthias,

I am not sure why it used ld form /opt/homebrew. If I run
Code:
which ld
I get
Code:
/usr/bin/ld

I have attached CMakeCache.txt.

Hi Matthias,

Did the CMakeCache.txt provide any info?
