Description
I'm trying to build several boost libraries like universal binaries for arm64 and x86_64 architectures. Firstly I've built it by providing for b2 two archs at once like this:
./b2 -arch x86_64 -arch arm64
but it doesn't work, because of boost-context cross-compilation. There is some assembly code and I feel that it needs some clarifying params, like: <architecture>, <address-model>, <binary-format> and <abi>. So build fails.
I try to build two slim binaries and with lipo create universal one.
Building x86_64 slim library on Macbook with Apple Silicone fails for boost-locale and boost-stacktrace libraries. As I understand about boost-locale, it can not find libiconv while building slim library.
So the question is, what's the proper way to build universal binaries for macOS using b2?
