Feature request: Mac aarch64 builds

[pettyalex]

Hello,

Thanks for this action, it's been super useful. Is there any chance of adding Apple Silicon builds to this, given that Github has apple silicon runners and ARM64 is the future of Mac OS in general?

This has also been asked here: https://github.com/MarkusJx/prebuilt-boost/issues/11 I'll look into it

[ciaranm]

I've been trying to use the binaries from MarkusJx/prebuilt-boost/issues/11, but it looks they're tagged as "arm64" whereas the install scripts expects "aarch64". Am I confused or is there a mismatch?

[MarkusJx]

The architecture for arm macos builds is arm64 (which is confusing, not sure why I did this). Is there a specific error while installing you may be able to provide?

[ciaranm]

According to https://github.com/MarkusJx/install-boost/blob/main/README.md#arch I should be specifying "aarch64" for "arch", and if I instead put "arm64" I get

but if I specify "aarch64" I instead get

My attempt at getting automatic builds using boost + macos 14 can be found in https://github.com/ciaranm/glasgow-constraint-solver/pull/53 .

[MarkusJx]

I see. I'll change the architecture for macos to aarch64. I'll post an update once that's done.

[MarkusJx]

I've only managed to rename the architecture for boost version 1.78.0.beta1 as it seems like github updated the runners to a new macOs SDK which does not allow me to build any older boost binaries.

[ciaranm]

Thanks. I can confirm that 1.78.0.beta1 at least partially works now. However, there are some incompatibility issues between Boost and XCode 15 that are fixed in 1.81 (https://github.com/boostorg/config/pull/440) which make older Boost versions largely unusable.

[MarkusJx]

I guess I've been seeing these issues whilst trying to rebuild version 1.78.0. I've simply renamed an older build of version 1.78.0.beta1 once I've noticed the older versions won't compile anymore. I'll rebuild all versions starting from 1.81.0, so you can at least use those newer ones.

[ciaranm]

Things are looking better: I can now use 1.84.0.beta1 on a macos-14 ARM image (see e.g. https://github.com/ciaranm/glasgow-constraint-solver/blob/main/.github/workflows/cmake.yml if anyone else is trying the same). It looks like 1.84.0 isn't there yet though.

[MarkusJx]

I've now re-built boost versions 1.81.0 through 1.84.0 for macos arm

[ciaranm]

Thanks, for me this is now working perfectly.

[MarkusJx]

I'll close this for now. Feel free to re-open if you encounter any issues.
