C++ Mountain Lion上的Mex文件：显式实例化错误

我正在山狮上使用MatlabR2012B，安装的XCode版本是4.6.1。我也在使用了补丁，然后我输入了“mex-setup”并选择了唯一可用的选项

1: /Applications/MATLAB_R2012b.app/bin/mexopts.sh : Template Options file for building gcc MEX-files

我正在尝试使用一个使用mex文件的稀疏建模框架（用C++编写）。为了安装之前的框架，我必须在框架内调用一个调用mex函数的matlab文件：然而，当我调用此函数时，我得到以下消息

./linalg/linalg.h:在成员函数“void Matrix:：print（const std:：string&）const[with T=float]”中：
/linalg/linalg.h:1084:从“std:：basic_ostream&std:：operator”实例化我通过行添加编译标志“-mmacosx version min=10.7”解决了这个问题

compile_flags=[compile_flags ' -mmacosx-version-min=10.7'];

在SPAMS框架的compile.m中，位于调用mex的for块之前

这个解决方案来自于其他软件包，并且似乎与其他软件包存在相同的问题。
我通过将mexopts.sh中的MACOSX_部署_TARGET='10.5'更改为'10.6'解决了类似的问题。
在线的是什么。/linalg/linalg.h:1083？该文件包含哪些标题？听起来它可能有一个转发声明（例如，来自
），但不是类模板的完整定义。您好，在第1083行有“std:：cerr”，乍一看，作者似乎没有包括其中包含stderr，但当我在雪豹上编译时，使用了以前版本的Xcode（和Matlab 2012a）没有问题！！！似乎fstream以前包括iostream，但现在没有了。解决方案可能很简单，只需将该文件更改为包含它。我曾尝试将#include添加到linalg.h中，但出现了相同的错误。
