I'm trying to get boost 1.53 to link to an app that is compiled for i386. This is on a mac that is 64 bit. It seems that boost is getting built by default as 64 bit so when I try to link to it, I get this error:

ld: warning: ignoring file /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/usr/local/lib/libboost_system.dylib, file was built for unsupported file format which is not the architecture being linked (i386)

I tried building boost via this command:

./b2 toolset=darwin cxxflags="-arch i386" address-model=32 stage

But it doesn't seem to make a difference. My linker settings are

-lboost_system -lboost_thread

Do I need to build boost a different way, or link to it differently?

Edit

Just figured out that this command seems to build it correctly:

./b2 toolset=darwin cxxflags="-arch i386" address-model=32 architecture=x86 stage

and do the same for install

./b2 install toolset=darwin cxxflags="-arch i386" address-model=32 architecture=x86 stage

您需要在目标配置中选择架构 i386：（Valid Architectures在Build Setting您的目标中）

但是，如果您正在构建应用程序，则有两种解决方案：

  • 构建应用程序 32 位，构建库的 32 位版本。
  • 构建 64 位应用程序。为此，请替换i386为x86_64和更改Architectures以及Valid Architectures。
