Compilation error on Apple Silicon

[Karl Schmid]

I tried to compile the most recent version mu-1.12.5 on my new MacBookPro M3, but got the following error message:

schmid@FlowerPowerProM3:~/Downloads/mu-1.12.5$ ninja -C build

Undefined symbols for architecture x86_64:

It seems that it expects some libraries for the x86 architecture that are available only for the native arm64 architecture.

Is it possible to compile somehow via Rosetta or directly for the arm64 architecture?

Best regards,

Karl

I’ve had no trouble building mu on an M2 silicon Mac. But these error messages look familiar.

A while back, one of my colleagues had *real* trouble with an Apple Silicon Mac and Homebrew (at least, I think it was homebrew related, I could be wrong). Migration from the previous Intel Mac to the new Mac with “migration assistant” or whatever Apple calls it, had apparently copied some x86 libraries over.

I tried everything I could think of, deleting Homebrew entirely, deleting /usr/local, etc. To no avail. In the end, we just had to burn the whole thing to the ground and reinstall MacOS.

I hope you’re not in a similar situation!

Be seeing you,
norm

I don't have such HW, so just some general advice; at the beginning of
the build, you should see something like this (with some details different):

From your output it seems as if your M3 (arm64) tries to cross-compile
to x86_64... and then tries to link against arm64 libraries. What does
meson tell you with its setup? E.g. I see something like:

The Meson build system
