Mex on Mavericks with R2012b
显示 更早的评论
I am running Matlab R2012b and updated to Mac OS Mavericks and Xcode 5. Now I can't compile my c++ code into mex files anymore: /Applications/MATLAB_R2012b.app/bin/mex: line 305: llvm-gcc-4.2: command not found /Applications/MATLAB_R2012b.app/bin/mex: line 1326: llvm-g++-4.2: command not found
What to do?

Can anybody provide a solution for R2013a? Thanks.

Hi,
I had the same problem. It seems that the new version of llvm-gcc is version 5.0. You can confirm the same for your system by typing
llvm-gcc --version
in terminal.
Assuming you've previously downloaded the MEX patch provided by Mathworks, my work-around was to modify the MacOSX 10.8 patch in the mexopts.sh file. For me this file was located in
/Users/<myname>/.matlab/R2012b/
At the bottom of the mexopts.sh file find the code block for #PATCH: MacOSX10.8 . Modify the following three lines to:
CC='llvm-gcc'
CXX='llvm-g++'
SDKROOT='/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/'
The version number was deleted from the definition of the first two variables. In the third variable's definition MacOSX10.8.sdk was changed to MacOSX10.9.sdk. Oddly, changing the the version from 4.2 to 5.0 in the first variables' definitions did not solve the problem, but completely deleting the version number did.
These changes allowed me to compile a project that was throwing the same error you were getting. Whether this work-around is best practice or not I don't know.

Thanks I was looking for this solution, I got as far as to change to 10.9 but didn't think to change the gcc/g++ versions so thank you.

This solution from rmm also works with R2012b on Mac OSX 10.11 Yosemite ! Thank you

First, type "mex -setup" to make sure the file mexopts.sh exists. Second, make sure the SDK folder exist /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/, if not look list the content of /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/ to see which one to use. Then it worked for me.

You should soft link the llvm compiler, In the terminal:
cd /usr/bin
sudo ln -fs clang llvm-gcc-4.2
sudo ln -fs clang++ llvm-g++-4.2
I think the Mathworks will release some patch for the problem later, but right now it works for me.

Does this work around work for C-code as well?
