Re: [boost] [release] Boost 1.83.0 Beta 1 Release Candidate 1 is available

If I'm not mistaken, there's a bug in Boost.Context that was fixed in develop but not in master that caused similar issues for ARM. It may be related. Ruben. On Thu, 6 Jul 2023, 16:45 Marshall Clow via Boost, wrote:

As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy.

I have successfully built the boost libraries for C++03/11/14/17/20/2b on Mac OS 13.4.1 with:

$ clang++ -v Apple clang version 14.0.3 (clang-1403.0.22.14.1) Target: x86_64-apple-darwin22.5.0

But on my M1 Mac: $ clang++ -v Apple clang version 14.0.3 (clang-1403.0.22.14.1) Target: arm64-apple-darwin22.5.0

Boost.Coroutine failed to build.

Which caused the build of Boost.Fiber to fail as well (C++11 and later)

There’s another error at the start of the build log that may be relevant:
