C++ 将boost编译为通用库（英特尔和苹果硅体系结构）

我正在尝试在MacOS上构建boost库作为动态库。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

始终显示生成的dylibs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build settings中设置

archs arm64 x86_64

，我就可以构建一个示例通用库

运行命令

/b2 cxflags=“-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"

我也遇到了同样的问题，这是为了为i386和x86_64创建通用二进制文件

为了总结答案，您需要运行两次

/b2

（使用不同的工具集，因为clang始终为x86_64构建，即使您通过了相应的CXXFlags）

这是我用来首先单独生成所需库的脚本，然后使用

lipo

！/bin/sh
rm-rf arm64 x86_64通用
./bootstrap.sh--with toolset=clang--with libraries=线程、系统、文件系统、程序选项、序列化
./b2 cxxflags=“-arch arm64”工具集=达尔文-a
mkdir-p arm64&&cp stage/lib/*.dylib arm64
./b2 toolset=clang cxflags=“-arch arm64-arch x86_64”-a
mkdir x86_64&&cp stage/lib/*.dylib x86_64
mkdir通用
对于arm64/*中的动态库；do
lipo-create-arch-arm64$dylib-arch-x86\u 64 x86\u 64/$（basename$dylib）-output-universal/$（basename$dylib）；
完成

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，它将构建一个现成的通用库。

以下内容适用于我在Big Sur上使用Xcode 12.2的情况。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"

我遵循的答案似乎是在macOS 10.15.7上使用Xcode 12.3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（或类似的选项），导致构建失败。使用

architecture=combine

不能像这样工作。相反，对我有效的是：

bootstrap.sh--使用toolset=clang darwin

和

cxxflags

，

cflags

和

linkflags

设置为

-arch x86_64-arch arm64

以及其他选项

x86_64构建：

b2工具集=clang darwin target os=darwin architecture=x86 stage

和

cxflags

，

cflags

和

linkflags

仅设置为

-arch x86_64

（加上其他选项）

arm64构建：

b2工具集=clang darwin target os=darwin architecture=arm abi=aapcs stage

和

cxflags

，

cflags

和

linkflags

仅设置为

-arch arm64

（加上其他选项）

将库与lipo合并

我还被迫设置ABI，因为自动猜测某些东西无法识别苹果硅目标，因此一些汇编文件没有编译，因此在构建过程中丢失了符号。最后，

armv4t

问题由

clangdarwin

工具集解决

目前唯一需要注意的是，这两个版本进入相同的架构/配置目录，可以通过自定义

user config.jam

或在每个

阶段之后立即调用
install
来解决，这就是我所做的

工作内容：


主机平台：英特尔
macOS 10.15.7
Xcode 12.3（已安装命令行工具）
Boost 1.75.0（依赖压缩和ICU库已编译为通用）
/bootstrap.sh——库=线程、系统、文件系统、程序选项、序列化和/b2工具集=达尔文-a cxflags=“-arch-arm64-arch-x86\u 64-isysroot/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk”
不构建通用库。使用
lipo
检查显示体系结构为
x86\u 64
仅此我使用了完整的命令：
\build\u boost.sh./bootsrap.sh with=“--除此之外--带文件系统--带测试”cxflags=“-fvisibility=hidden-fvisibility inlines hidden-std=c++17-stdlib=libc++-arch x86_64-arch arm64-mmacosx version min=10.11-isysroot/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk”cflags=“-mmacosx version=10.11”链接标志=”-std=c++17-stdlib=libc++-arch x86_64-arch arm64-mmacosx version min=10.11“
Then
/b2-q-a-j8 architecture=combined toolset=darwin link=static runtime link=static threading=multi\cflags=“$cflags”cxflags=“$cxfflags”mflags=“$cflags”mmflags=“$cflags”linkflags=“$cflags”linkflags=“$linkflags"\--stagedir=stage variant=release$with
使用
lipo-archs libboost\u文件系统进行验证。x86\u 64 arm64
请确保您使用了最新的XCode 12.2，因为12.1没有arm位。我无法用您的命令重现这一点，您构建的是哪个boost版本？我正在尝试
1.74.0
构建boost 1.74。0，macOS Catalina，XCode 12.2+命令行工具关键是使用
architecture=combined
以及
-isysroot
。您遇到了什么错误？您在这里构建了什么版本的Boost？@jamieguinan。在我写下这个答案后几天，版本1.75.0就发布了，但我还没有尝试构建它。构建1.75.0 w在Big Sur（英特尔）下的Xcode 12.4中，我用这种方法得到了Navan Chauhan在上面的回复中提到的问题——静态lib是通用的，但动态lib只有x86_64。
