Apple Silicon build not supported.

[ibrewster]

When attempting to install bjoern on my apple silicon M1 mac using pip install bjoern the build fails with a number of "Architecture not supported" errors (see full output below). I can get it to build and install by prepending ARCHFLAGS="-arch x86_64" to the pip install command, but then the installed binary can't be imported due to "incompatible architecture" issues.

I have a similar issue, are there any fixes in the pipeline? Running Windows

[ibrewster]

I took another look at this today, and managed to get bjoern to compile on my Apple Silicon M1 Mac by:

1. Using the homebrew installed version of python3.11 rather than the python package installed version
2. Running the following commands:

xcrun --show-sdk-path
CFLAGS="-I /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include" pip install -I --no-cache-dir bjoern

where the argument to -I in the CFLAGS environment variable is the output of the xcrun --show-sdk-path command with /usr/include appended to it.

So apparently the issue is more environment related than bjoern specifically, though bjoern does something differently than at least some other packages that triggers the issue.
