我想用 clang 构建 boost，我安装了最新的 xcode 和命令行工具。编译b2现在我尝试：

-mac:boost_1_53_0 tim$ ./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++" --prefix="./install-dir" debug release install

并获得下一个作为输出：

所以我有一个基本问题：如何解决此类错误？

如果不构建调试版本，错误就会消失。看起来您无法在同一目录中安装调试库和发布库。

此命令有效

./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++" --prefix="./install-dir" release install

顺便说一句，可以在 mac（和 linux）上的应用程序的调试版本中链接 release boost 库。你不需要调试版本，除非你想调试提升。

这与 Windows 上的 VisualStudio 不同，您需要 boost 的调试版本才能链接到应用程序的调试版本。
