I am trying to compile playrec in matlab using mex, so a c++ compiler is needed. I am using OS X 10.9.2, matlab R2014a, and XCode 5.1 .

This is the errors I get:

Error using mex
clang: warning: no such sysroot directory:
'/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -std=c99'
In file included from /Users/LordTengil/Downloads/PlayrecForMatlab-playrec-48b4f6a/src/mex_dll_core.c:88:
In file included from /Applications/MATLAB_R2014a.app/extern/include/mex.h:57:
/Applications/MATLAB_R2014a.app/extern/include/matrix.h:23:10: fatal error: 'stdlib.h' file not found
#include <stdlib.h>
         ^
1 error generated.

The first warning I do not understand: I can find MacOSX10.8.sdk in exactly that directory. I am guessing the error of not finding stdlib.h is because of that first warning.

I get the same error. My setup is OS X 10.10.3, Matlab 2015a, and Xcode 6.3.2. Any suggestions for a fix? There are some fixes modifying the mexoptions.sh -file but that's no longer used in 2015a.

Here's my error message for reference..

The -std=c99 has been added in as part of the directory name. Notice the closing quote is not until after the -std=c99 . Somewhere in one of the configuration steps, the directory is being configured incorrectly.
