c++ - 将 boost 编译为通用库(Intel 和 Apple Silicon 架构)

Question

我正在尝试在 MacOS 上将 boost 库构建为 dylib。我需要为 Intel 架构和即将推出的 Apple Silicon (arm64) 架构构建它。
我下载了 boost 并运行了以下命令:

./bootstrap.sh
./b2 -address-model=64 architecture=combined -a

lipo -archs总是显示生成的 dylibs 架构是 x86_64 .
我有 Xcode12 beta 和 MacOS Catalina 10.15.7，
如果我在 Xcode 中创建一个项目并设置 archs arm64 x86_64，我可以构建一个示例通用库在build设置中。
运行命令 ./b2 cxxflags="-arch arm64 -arch x86_64"失败并出现以下错误:

    "clang++" -x c++ -fvisibility-inlines-hidden -m64 -O3 -Wall -fvisibility=hidden -Wno-inline -arch arm64 -arch x86_64 -ftemplate-depth-255 -fvisibility=hidden -fvisibility-inlines-hidden -DBOOST_ALL_NO_LIB=1 -DNDEBUG -I"." -c -o "bin.v2/libs/serialization/build/clang-darwin-12.0/release/link-static/threading-multi/visibility-hidden/polymorphic_xml_iarchive.o" "libs/serialization/src/polymorphic_xml_iarchive.cpp"

以下内容适用于使用 Xcode 12.2 在 Big Sur 上的我。在 Catalina 10.15.7 (19H15) 上，我收到与 OP 相同的错误消息。

./bootstrap.sh --with-libraries=regex,date_time 
./b2 architecture=combined cxxflags="-arch x86_64 -arch arm64"
