将boost编译为通用库(Intel和Apple Silicon架构)

我正试图在MacOS上以dylib的形式构建boost库。我需要为英特尔架构和即将推出的苹果硅(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总是表示生成的dylib体系结构是x86_64。

我有Xcode12测试版和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，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，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"

我在蒙特利使用M1(XCode 13.1(，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，使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

这个脚本打印出universal目录中每个dylib的lipo信息，因此您可以快速看到每个dylib内部都有x86_64和arm64。我得到了以下结果，也许这对你来说很有用，看看你的输出是否匹配：

以下内容适用于使用Xcode 12.2的Big Sur。在Catalina 10.15.7(19H15(上，我得到了与OP.相同的错误消息

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

在这里花费大量时间后：

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

我能够在arm64上编译boost。命令行是：

/b2体系结构=arm地址模型=64 asmflags=--target=arm64-apple-darwin21.2.0 cflags=--target=arm64-apple-darwin 21.2.0 cxxflags=--target=arm 64-apple-darwin21.20链接flags=--target=arm64-apple-darwin21.2.0-s NO_LZMA=1-s NO_ZSTD=1 abi=aapcs

LZMA和ZSTD标志就在那里，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，并得到了这个答案，它是为i386和x86_64创建通用二进制文件。

为了总结答案，您需要运行./b2两次(使用不同的工具集，因为clang总是为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

我遵循了Navan Chauhan的答案，这似乎是使用Xcode 12.3在macOS 10.15.7上运行的方法。

我唯一的问题是，构建系统添加了额外的-arch armv4tclang选项(或类似的选项(，导致构建失败。使用architecture=combine无法很好地工作，因为它只能管理英特尔和PowerPC。相反，对我有效的是：

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
x8_64内部版本：仅将b2 toolset=clang-darwin target-os=darwin architecture=x86 stage和cxxflags、cflags和linkflags设置为-arch x86_64(加上其他选项(
arm64内部版本：b2 toolset=clang-darwin target-os=darwin architecture=arm abi=aapcs stage和cxxflags、cflags和linkflags仅设置为-arch arm64(加上其他选项(
将库与lipo合并

我被迫将ABI设置为自动猜测某些东西无法识别Apple Silicon的目标，因此一些汇编内容没有编译——因此在稍后的构建过程中丢失了符号。最后利用clang-darwin工具集解决了armv4t问题。

目前唯一需要注意的是，两个构建都进入相同的体系结构/配置目录，可以通过自定义user-config.jam或在每个stage之后立即调用install来解决，这就是我所做的。

工作于：

主机平台：Intel
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库已编译为通用库(

您不需要使用lipo，您可以通过-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk到cxxflags，它将开箱即用地构建一个通用库。

检查macOS M1 building boost 1.82.0，成功构建包含两种架构的胖二进制文件：

./bootstrap.sh
./b2 -a address-model=64 architecture=arm+x86

要在系统范围内安装：

sudo ./b2 -a address-model=64 architecture=arm+x86 install

已检查是否已成功链接。请放心使用：

lipo -info /usr/local/lib/libboost_chrono.dylib
Architectures in the fat file: /usr/local/lib/libboost_chrono.dylib are: x86_64 arm64

希望能有所帮助。
