更新：我在 mexopts.sh 中安装了 XCode 并更改了 SDKROOT 以反映此处描述的实际路径，但是当我包含 mex.h 时仍然出现此错误：

In file included from /Applications/MATLAB_R2012b.app/extern/include/matrix.h:294,
                 from /Applications/MATLAB_R2012b.app/extern/include/mex.h:58,
                 from test.c:2:
/Applications/MATLAB_R2012b.app/extern/include/tmwtypes.h:61:21: error: float.h: No such file or directory

    mex: compile of ' "test.c"' failed.

我正在尝试通过 mex 编译一个用于 Matlab 的简单 C 文件，但它似乎永远找不到我知道已安装的默认库。例如，尝试编译以下内容：

#include <string.h>
int main() {
    return 0;
}

给我错误：

test.c:1:20: error: string.h: No such file or directory
mex: compile of ' "test.c"' failed.

即使它使用 gcc 编译得很好。更糟糕的是，当我尝试像这样包含 mex.h 时：

#include "mex.h"
int main() {
    return 0;
}

我收到以下错误：

我认为 mex 没有为这些库寻找正确的位置，或者安装以某种方式损坏，但我不知道如何修复它。

Mac OSX Mountain Lion + XCode 4.5.2，Matlab R2012b，gcc 4.2.1

只是为了分享，我有类似的问题。我正在运行相同版本的 Matlab 并且正在查看此页面但找不到答案。我在这里找到了答案：Matlab 2012a Mex to work with Xcode 4.5 on Mountain Lion

包含文件需要在您的PATH中（键入路径以显示这些文件夹），除非您使用mex -Ipathname专门包含它们。您可以单击“文件->设置路径”并添加包含您的 string.h 的文件夹。

使用命令指定以下选项，mex它将正常工作。请确保您在以下文件夹中有标准头文件，否则请相应更新：

mex -I'C:\Program Files (x86)\Windows Kits\10\Include\10.0.10150.0\ucrt'.

如果你克服了这个错误，它也可能会为 .lib 提供帮助。包括类似的

mex -I'C:\Program Files (x86)\Windows Kits\10\Include\10.0.10150.0\ucrt' -L'C:\Program Files (x86)\Windows Kits\10\Lib\10.0.10150.0\ucrt\x64'
