Mex yprime.c compile failed matlab r2010a mac os x 10.6.6 xcode 4 gcc v4.2.1

Plain Text

Dear all,

I am new to this topic. I just wanted to follow the steps to build a mex file from my mac. I am using a matlab r2010a on a mac with os x 10.6.6. I have the xcode4 installed.

After typed in mex -setup in the matlab prompt, the output are as follows,

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 ~/.matlab/R2010a 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 ~/.matlab/R2010a.

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_R2010a.app/bin/gccopts.sh :
Template Options file for building gcc MEX-files

2: /Applications/MATLAB_R2010a.app/bin/mexopts.sh :
Template Options file for building MEX-files via the system ANSI compiler

0: Exit with no changes

Enter the number of the compiler (0-2):
2

Overwrite /Users/neilhan0210/.matlab/R2010a/mexopts.sh ([y]/n)?
y

/Applications/MATLAB_R2010a.app/bin/mexopts.sh is being copied to
/Users/neilhan0210/.matlab/R2010a/mexopts.sh

Then I typed in mex yprime.c (it is in the current matlab directory), the results are as follows,

??? Error using ==> mex at 222
Unable to complete successfully.

Looks like the Matlab can't find the gcc compiler. Anyone had a similar problem and solved it please helps.

Any suggestions are appreciated.

Thanks
