address-model=64 architecture=arm target-os=darwin generates x86_64 output

[autoantwort]

This was reported by microsoft/vcpkg#16630 and I can reproduce it on my machine with lipo -archs libboost_system.a which returns x86_64

[autoantwort]

Ok, it seems that the problem is the --hash parameter. Without --hash it will produce arm64 binaries, with --hash x86_64

Hi, is it possible that we can build universal libraries for boost? Here is my command:
./b2 --prefix="/Users/zhaoma/USD-21.02/output/3prelease" --build-dir="/Users/zhaoma/USD-21.02/release/build" -j12 address-model=64 link=shared runtime-link=shared threading=multi variant=release --with-atomic --with-program_options --with-regex toolset=clang architecture=combined cxxflags="-arch x86_64 -arch arm64" install

However when I check:

lipo -archs /Users/zhaoma/USD-21.02/release/build/boost/bin.v2/libs/program_options/build/clang-darwin-12.0/release/architecture-combined/threading-multi/visibility-hidden/libboost_program_options.dylib 
x86_64

I am using boost 1.72.0 any suggestions? Thank you!

@autoantwort run b2 with -d+2 flag to make logs useful. A log with --debug-building may later be required to debug too.

Not yet, and I am not sure if adding such a thing would be an easy task. Try contacting Apple, maybe they could offer a help to Boost.

Thank you for your contributions. Main development of B2 has moved to https://github.com/bfgroup/b2
This issue has been automatically marked as "transition" to indicate the potential for needing transition to the new B2 development project.
