Mex file error when installing libsvm on macosx elcapitan with xcode 7.1.1. and MATLAB R2013a

Hi there,

I have just updated to OSX ELCapitan 10.11.1 and have MATLAB R2013a and XCode 7.1.1 and trying to install libsvm. I have followed the procedures that I had posted earlier in the following post

http://www.mathworks.com/matlabcentral/answers/250285-trouble-installing-libsvm-on-macosx-10-10-5-matlab-r2013a-with-xcode7-0-1

which includes the solution proposed in the following links

http://www.mathworks.com/matlabcentral/answers/246507-why-can-t-mex-find-a-supported-compiler-in-matlab-r2015b-after-i-upgraded-to-xcode-7

On compiling the

mex -setup

I am getting

    Options files control which compiler to use, the compiler and link command
    options, and the runtime libraries to link against.

    Using the 'mex -setup' command selects an options file that is
    placed in /Users/HP/.matlab/R2013a and used by default for 'mex'. An options 
    file in the current working directory or specified on the command line 
    overrides the default options file in /Users/HelenPanni/.matlab/R2013a.

    To override the default options file, use the 'mex -f' command
    (see 'mex -help' for more information).

The options files available for mex are:

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

0: Exit with no changes

Enter the number of the compiler (0-1):
1

Overwrite /Users/HP/.matlab/R2013a/mexopts.sh ([y]/n)? 
y

/Applications/MATLAB.app/bin/mexopts.sh is being copied to 
/Users/HP/.matlab/R2013a/mexopts.sh

And when I run file

make.m

I am getting this error

clang: warning: no such sysroot directory: '-mmacosx-version-min=10.11'
libsvmread.c:1:10: fatal error: 'stdio.h' file not found
#include <stdio.h>

1 error generated.

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

If make.m fails, please check README about detailed instructions.

Ok I have got it working just need to change line 136 to this

CFLAGS="-fno-common -arch $ARCHS -isysroot $MW_SDKROOT -mmacosx-version-min=$MACOSX_DEPLOYMENT_TARGET -Dchar16_t=UINT16_T"

Follow the above mentioned steps and change line 136 to the above it will work.
