Compile Fails on macOS due to PyInstaller

[lbibass]

When attempting to compile Cura, pyinstaller throws this error:

It seems it's trying to load non-executable files as executables. I'm not sure how to fix this.

Which minor version of Python are you using. There was a bug in pyinstaller which requires at least 3.10.4

[jellespijker]

Are you compiling on a M1?

[lbibass]

Are you compiling on a M1?

Yes, I am.

[jellespijker]

Then you have to use the Rosetta terminal. We don't support native ARM yet.

[lbibass]

That's too bad. QT6 supports it, and all the other aspects of the compilation process should work.

[lbibass]

So this is bizarre. It just... compiled for me? Not sure what happened, but it worked. Apple Silicon native Cura!

[jellespijker]

That is very interesting and unexpected. Can you share the binaries.

[lbibass]

Sure. How would you like me to share them?

[lbibass]

I have figured out what I did in order to get it to compile: I had to completely delete the build folder and build from scratch. Attempting to rebuild in a directory that has already been used to compile Cura causes the error.

What a bizarre glitch.

[jellespijker]

Consistency is key in these kind of scenarios. Start with a fresh build folder. Make sure the cmake project is configured and build In the correct terminal. Also check if the python you're using isn't the pure Intel variant.

[jellespijker]

I hope you will get there, and I can help you a long a bit, if time allows it, but I will close this issue since we don't officially support ARM. But feel free ask and this thread.

If the arm approach fails use the Rosetta terminal. Just make sure you're consistent in that approach, so no messing up binaries from different architectures
