[package] boost/1.75.0: Apple-clang cannot cross-compile for arm64 on x86_64 hosts

[dgaribaldi]

In order to build boost for Apple silicon, I'd like to cross-compile boost libraries on my x86_64 dev machine so that I can eventually build other software with both arm64 and x86_64 versions of the library using Conan's cmake_multi generator.

While attempting to cross-compile for arm64, I ran into three issues right off the bat, and I suspect there are more lurking farther beyond.

First off, b2 needs to be told to use a 64-bit address model when the arm64 arch is specified. This check is missing.

Secondly, the to_apple_arch() conversion from the conan-package-tools library used here returns None, which causes b2 to pass "-arch None" to the compiler which then promptly fails. This should be updated with either a special case for arm64, or conan-package-tools needs to be updated to correctly handle this input (which just should just return "arm64").

Thirdly, the test_package conanfile.py needs to propagate the settings.arch value to the CMAKE_OSX_ARCHITECTURES value definition. Right now, it's being set to the host architecture (x86_64) by default.

There seem to be some other issues actually getting the tests to run, and I haven't tried to get boost::locale library to build properly yet, but that will likely have issues building as well. I am happy to create a dev branch with the fixes I indicated, but I still don't know where to go from here in debugging the tests. Let me know if there's any more information I can provide as well. Thanks!

please open a PR with any fixes!

The test not running seems normal at first glance... they are skipped when cross building

you better use -s arch=armv8 instead of arm64. right now, boost cross-compiles successfully from x86_64 to arm64 (M1), and it's being tested on CI.

[SSE4]

but I agree we should prevent this error message:

clang: error: invalid arch name '-arch None'

I'll add a necessary sanity check, so it won't try to pass None for unrecognized architectures.

[perseoGI]

Hi there,
I was reviewing old issues and I have come across this one.
Is this issue still active?
I don't have actually an x86_64 environment to test this out!

Thank you in advance :)

[dgaribaldi]

Hello! I'm afraid I can't tell you whether or not this is still an active issue, as I unfortunately no longer have the x86-based Apple machine that I used to cross-compile and reproduce these errors in the first place. I'll go ahead and close it accordingly; thank you for following up!
