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。我需要为英特尔架构和即将推出的 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archs arm64 x86_64在构建设置中进行设置，我可以构建一个示例通用库。

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"

以下适用于我在 Big Sur 上使用 Xcode 12.2。在 Catalina 10.15.7 (19H15) 上，我收到与 OP 相同的错误消息。

我在 Monterey 使用 M1（XCode 13.1）并未能获得任何其他答案，但我将Navan和Petr的内容与其他一些位结合起来，让 libboost_coroutine 在 x86_64 上工作。我得到了以下脚本，它构建了所有的 boost 库（为什么不呢，在 M1 上不需要很长时间）：

#!/bin/sh

rm -rf arm64 x86_64 universal stage bin.v2
rm -f b2 project-config*
./bootstrap.sh cxxflags="-arch x86_64 -arch arm64" cflags="-arch x86_64 -arch arm64" linkflags="-arch x86_64 -arch arm64"
./b2 toolset=clang-darwin target-os=darwin architecture=arm abi=aapcs cxxflags="-arch arm64" cflags="-arch arm64" linkflags="-arch arm64" -a
mkdir -p arm64 && cp stage/lib/*.dylib arm64
./b2 toolset=clang-darwin target-os=darwin architecture=x86 cxxflags="-arch x86_64" cflags="-arch x86_64" linkflags="-arch x86_64" abi=sysv binary-format=mach-o -a
mkdir x86_64 && cp stage/lib/*.dylib x86_64
mkdir universal
for dylib in arm64/*; do 
  lipo -create -arch arm64 $dylib -arch x86_64 x86_64/$(basename $dylib) -output universal/$(basename $dylib); 
done
for dylib in universal/*; do
  lipo $dylib -info;
done

该脚本打印出universal目录中每个 dylib 的 lipo 信息，因此您可以快速看到每个内部都有 x86_64 和 arm64。我得到了以下结果，也许看看你的输出是否匹配对你有用：

在这里花了相当多的时间后：

https://github.com/bfgroup/b2/issues/105

我能够在 arm64 上编译 boost。命令行是：

./b2 架构=arm 地址模型=64 asmflags=--target=arm64-apple-darwin21.2.0 cflags=--target=arm64-apple-darwin21.2.0 cxxflags=--target=arm64-apple-darwin21.2.0 linkflags=--target=arm64-apple-darwin21.2.0 -s NO_LZMA=1 -s NO_ZSTD=1 abi=aapcs

LZMA 和 ZSTD 标志在那里，因为我的机器上没有这些库的通用二进制文件。

我遇到了同样的问题并遇到了这个答案，它是为 i386 和 x86_64 创建通用二进制文件。

总结答案，您需要运行./b2两次（使用不同的工具集，因为 clang 始终为 x86_64 构建，即使您通过了适当的 CXXFlags

这是我用来首先单独生成我需要的库然后使用组合它们的脚本lipo

#!/bin/sh

rm -rf arm64 x86_64 universal
./bootstrap.sh --with-toolset=clang --with-libraries=thread,system,filesystem,program_options,serialization 
./b2  cxxflags="-arch arm64" toolset=darwin -a
mkdir -p arm64 && cp stage/lib/*.dylib arm64
./b2 toolset=clang cxxflags="-arch arm64 -arch x86_64" -a
mkdir x86_64 && cp stage/lib/*.dylib x86_64
mkdir universal
for dylib in arm64/*; do 
  lipo -create -arch arm64 $dylib -arch x86_64 x86_64/$(basename $dylib) -output universal/$(basename $dylib); 
done

我遵循了Navan Chauhan的回答，这似乎是在 macOS 10.15.7 上使用 Xcode 12.3 的方式。

我唯一的问题是构建系统正在添加额外的-arch armv4tclang 选项（或类似的东西），这会使构建失败。使用它architecture=combine不能很好地工作，因为它只能管理 Intel 和 PowerPC。相反，对我有用的是：

bootstrap.sh --with-toolset=clang-darwin和cxxflags,cflags并linkflags设置为-arch x86_64 -arch arm64plus 附加选项。
x86_64 build:b2 toolset=clang-darwin target-os=darwin architecture=x86 stage和cxxflags,cflags并linkflags设置为-arch x86_64only（加上其他选项）。
arm64 build:b2 toolset=clang-darwin target-os=darwin architecture=arm abi=aapcs stage和cxxflags,cflags并linkflags设置为-arch arm64only（加上其他选项）。
将库与……合并lipo。</li>

我也被迫设置 ABI，因为自动猜测的东西无法识别 Apple Silicon 目标，因此某些组装内容未编译 - 因此在构建过程中稍后会丢失符号。最后这个armv4t问题被clang-darwin工具集解决了。

目前唯一需要注意的是，两个构建都进入相同的架构/配置目录，可以通过自定义或在每个构建之后user-config.jam立即调用来解决，这就是我所做的。installstage

适用于：

主机平台：英特尔
macOS 10.15.7
Xcode 12.3（安装了命令行工具）
Boost 1.75.0（已编译为通用的相关压缩和 ICU 库）

你不需要使用 lipo，你可以传递 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk给 cxxflags，它会构建一个开箱即用的通用库。
