Installing finufft on M1 Mac arm64: include and architecture errors after troubleshooting
Hi! I've tried installing finufft for python use on my M1 mac through pip, the wheel file above, and also by compiling manually. Unfortunately, I keep running into the same issues. First, when I make test -j I run into several "fatal errors" saying " 'omp.h' file not found" in the include lines.
Second, when I try importing it in python 3, I get the same error as the original comment.
I am trying to use this package for some radio antenna work involved in my research. Please let me know what you advise!
Hi, did you brew install libomp ? If so, then it could be a matter of searching for omp.h and explicitly adding directory via adding a -Idirectory to flags in whatever make.inc you're using. Layouts of OS systems change. Search for related fixes, eg https://github.com/lczech/gappa/issues/15
@lu1and10 may have more input, as a mac user. Keep us updated, esp if you have updates that work - we will add them to our docs and make.inc versions. Best, Alex

Not the original user but I am getting the exact same errors either when installing through pip3 or building myself in PyCharm. Is there any solution to make it work ?

We have not include pip binary wheels for m1,m2, we will include in the next release.
It turns out that brew changes the libomp lib and include files directory(not in /opt/homebrew/lib and /opt/homebrew/include), I just updated make.inc.macosx_arm64. You could follow the instruction install libomp and fftw using brew and then use the latest make.inc.macosx_arm64 to try to build from source.
Note we have cmake for C++ build, and we are switching to use skbuild for python in the next release, so makefile may be deprecated in the next release.
In case others stumble upon this: in my case, after failing to use finufft on arm64 (couldn't build from source), the easiest was to set an x86 environment (see e.g. here). Install with pip install finufft worked fine then.
