在OS X上有两个标准C ++库的实现：libstdc ++和libc ++，它们不是二进制兼容的，libMLi3需要libstdc ++。 / p>

在10.8和早期版本中，默认选择libstdc ++，10.9为了确保与libMLi3兼容，我们需要手动选择libstdc ++。 b
$ b

为此，请将-stdlib = libstdc ++添加到链接命令中。

使用Libc ++编译未定义的引用

编辑：经过一番调查后，似乎-mmacosx-version-min的默认libstd。如果min版本

There are two implementations of the standard C++ library available on OS X: libstdc++ and libc++. They are not binary compatible and libMLi3 requires libstdc++.

On 10.8 and earlier libstdc++ is chosen by default, on 10.9 libc++ is chosen by default. To ensure compatibility with libMLi3, we need to choose libstdc++ manually.

To do this, add -stdlib=libstdc++ to the linking command.

Edit: After some investigations it seems there is a link between the "-mmacosx-version-min" and the choice of the default libstd. If min version < 10.9, then the default libstd is equal to "libstdc++", else to "libc++". The long term solution is clearly to use "-stdlib=libc++"
