Question

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，我下载了boost。我一直收到这个错误：

我在使用MacOSX10.7.sdk在Maverick上构建Boost 1.55.0时也是如此。所以我在编译命令中为cflags和cxxflags选项添加了-I/usr/include。它解决了这个问题。我完整的命令。

./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

在OS X Mavericks上为Android构建Boost库
