我在尝试为 android 构建 boost 库时遇到问题。我安装了苹果命令行工具并下载了 boost。我一直收到此错误：

在使用 MacOSX10.7.sdk 在 Maverick 上构建 Boost 1.55.0 时，我得到了同样的结果。所以我在编译命令的 cflags 和 cxxflags 选项中添加了-I/usr/include。它解决了这个问题。我的全部命令。

./b2 -d+2 toolset=clang cxxflags="-stdlib=libc++ -isysroot=$SDKROOT -mmacosx-version-min=$MACOSX_DEPLOYMENT_TARGET -I/usr/include" cflags="-stdlib=libc++ -isysroot=$SDKROOT -mmacosx-version-min=$MACOSX_DEPLOYMENT_TARGET  -I/usr/include" --layout=system --build-type=minimal --prefix=$QTDIR link=static runtime-link=static variant=release install
