Like clockwork, my matlab updates have gotten out of sync with Xcode updates. It seems like fixing this SDK error always requires a different hack each year. This year I got the error:

No supported compiler or SDK was found. For options, visit 

To fix it, I replaced all occurrences of 10.9 with 10.11 in /Applications/{++,}_maci64.xml

I’m still getting linker warnings:

ld: warning: object file was built for newer OSX version (10.11) than being linked (10.9)

For now, I’m assuming that I can ignore them. We’ll see how far that gets me.

    Yet another time I’ve been frustrated trying to figure out where matlab is finding it’s mex options. This time I realized the answer is right in front of me. If you pass the -v (verbose) flag to your mex compile, you should see a whole bunch of debug messages including something like:

    Options file: /Users/ajx/Library/Application Support/MathWorks/MATLAB/R2017a/mex_C++_maci64.xml

    Replacing all 10.9s with 10.11s fixed the remaining problem above.
