Matlab编译mex文件时找不到标准的C库

cmatlabmex
4

更新：我安装了XCode并在mexopts.sh中更改了SDKROOT以反映实际路径，如此处所述，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来编译一个简单的C文件，以便在Matlab中使用，但似乎从未找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;
}

出现错误：

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

尽管使用gcc编译没有问题，但更糟糕的是，当我尝试这样包含mex.h时：

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

I get the following error:

我猜测mex没有在正确的位置寻找这些库文件，或者安装文件已经损坏了，但我不知道如何修复它。
Mac OSX Mountain Lion + XCode 4.5.2, Matlab R2012b, gcc 4.2.1
如果你甚至没有包含任何库，那你能编译吗？ - Dennis Jaheruddin
如果我不包含任何库并删除对mex特定类型（如mxArray）的任何引用，则编译正常。 - David Pfau

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

使用mex命令指定以下选项即可正常工作。请确保您在以下文件夹中拥有标准的头文件，否则请相应更新：
mex -I'C:\Program Files (x86)\Windows Kits\10\Include\10.0.10150.0\ucrt'.

如果您成功解决了这个错误，可能还需要添加 .lib 文件。类似地加入即可。
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'
