将boost编译为通用库Intel和Apple Silicon体系结构

编程问答 2022-06-06

问题描述

我正在尝试在MacOS上将dylib创建为dylib。我需要同时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始终显示生成的dylibs架构是x86_64。

我有Xcode12 beta和MacOS Catalina 10.15.7，

如果我在Xcode中创建一个项目并在构建设置中设置archs arm64 x86_64，则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"

解决方法

以下内容适用于使用Xcode 12.2的Big Sur。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"
,

我也遇到了同样的问题，并遇到了这个answer，它是为i386和x86_64创建通用二进制文件。

要总结答案，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，即使您传递了适当的CXXFlags

这是我用来首先单独生成所需库，然后使用lipo

组合它们的脚本 
#!/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
,

您不需要使用脂质，可以通过 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk到cxxflags，它将立即建立通用库。

我遵循了 documentation 的答案，这似乎是使用 Xcode 12.3 在 macOS 10.15.7 上的方法。

我唯一的问题是构建系统添加了额外的 -arch armv4t clang 选项（或类似的东西），这导致构建失败。使用 architecture=combine 的效果不如 Navan Chauhan。对我有用的是：

  1. bootstrap.sh --with-toolset=clang-darwin 和 cxxflags、cflags 和 linkflags 设置为 -arch x86_64 -arch arm64 以及其他选项。
  2. x86_64 构建：b2 toolset=clang-darwin target-os=darwin architecture=x86 stage 和 cxxflags、cflags 和 linkflags 仅设置为 -arch x86_64（以及其他选项）。
  3. arm64 构建：b2 toolset=clang-darwin target-os=darwin architecture=arm abi=aapcs stage 和 cxxflags、cflags 和 linkflags 仅设置为 -arch arm64（以及其他选项）。
  4. 将库与 lipo... 合并

我也被迫设置 ABI，因为 automatic-guess-something 无法识别 Apple Silicon 的目标，因此某些组装内容未编译 - 因此 缺少符号 稍后在构建期间。最后，armv4t 问题由 clang-darwin 工具集解决。

目前唯一的警告是两个构建都进入相同的架构/配置目录，这可以通过自定义 user-config.jam 或在每个 {{1} 之后立即调用 install 来解决}} 这就是我所做的。

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（依赖压缩和 ICU 库已经编译为通用）
