Could anyone know how to use Xcode 5.0 as my C or C++ compiler in MATLAB 2012b or later?

MAC OS X 10.8.5

Xcode 5.0 (command line tools have installed)

Matlab 2012b

>> mex -setup

    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/Yydai168/.matlab/R2012b 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/Yydai168/.matlab/R2012b.

    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_R2012b.app/bin/mexopts.sh : 
    Template Options file for building gcc MEX-files

0: Exit with no changes

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

Overwrite /Users/Yydai168/.matlab/R2012b/mexopts.sh ([y]/n)? y

/Applications/MATLAB_R2012b.app/bin/mexopts.sh is being copied to /Users/Yydai168/.matlab/R2012b/mexopts.sh

The ERROR:

>> mex test.c /Applications/MATLAB_R2012b.app/bin/mex: line 305: llvm-gcc-4.2: command not found /Applications/MATLAB_R2012b.app/bin/mex: line 1326: llvm-gcc-4.2: command not found

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

Error using mex (line 206) Unable to complete successfully.

I have the same problem here. Matlab 2013a and Xcode 5.0

[dai]

I have solved it.

update matlab 2013a from matlab 2012b

install ”command line tools“ of xcode5.0

and replace ”10.7“ with ”10.8“ in /Applications/MATLAB_R2013a.app/bin/mexopts.sh

Good luck.

[Ken Atwell]

Dai got it right, replace "10.7" with "10.8" in mexopts.sh. Here is the MathWorks for this:

I have the same problem with Xcode 5.0 and MATLAB 2012b

I know that there is a solution for 2013a and 2013b:

http://www.mathworks.de/support/solutions/en/data/1-OAMYBZ/

but I need one for 2012b...!

Even this could not help me:

http://www.mathworks.de/support/solutions/en/data/1-FR6LXJ/

I always get:

/Applications/MATLAB_R2011b.app/bin/mex: line 305: llvm-gcc-4.2: command not found

I have the same problem. Xcode 5.0 & Matlab 2012b.

[Jorik]

That error seems to indicate you did not install the command-line tools.

Did you install them as indicated by the solution page 1-FR6LXJ you refer to? It is listed under "*** Before applying the patch *" Step 2.

It seems that with Xcode 5 you can download the command-line tools from: https://developer.apple.com/downloads/index.action#

I am having the same problems... is it possible there are some compatibility problems with the new mac os x 10.9 (mavericks)?

• I am runnin MATLAB 2012b with Xcode 5.0 (on os 10.9)
• I have command-line tools installed on Xcode 5.0
• I've tried installing the patch
• !xcodebuild -version identifies the correct version of Xcode
• I have run mex -setup

I still receive the error

Making simulation target "bearing_sfun", ...

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

gmake: * [bearing_sfun.o] Error 1

any ideas? This is becoming a serious time sync!

thanks in advance, dan

[edit] I found this post that solved the problem for my setup http://www.mathworks.com/matlabcentral/answers/103258-mex-on-mavericks-with-r2012b
