Does anybody know why I get the error,
Error using mex
No supported compiler or SDK was found. For options, visit
http://www.mathworks.com/support/compilers/R2016a/glnxa64.html.
I'm using matlab R2016a on ubuntu linux with gcc 4.7, which should be supported. Also tried earlier with gcc 4.8, same error.
>>!gcc -v
Using built-in specs.

>>mex -setup
MEX configured to use 'gcc' for C language compilation.
Warning: The MATLAB C and Fortran API has changed to support MATLAB
variables with more than 2^32-1 elements. In the near future
you will be required to update your code to utilize the
new API. You can find more information about this at:

To choose a different language, select one from the following:
mex -setup C++
mex -setup FORTRAN
thanks!

Mike - what is written to the console when you enable verbosity?

mex -setup -v
Verbose mode is on.
... Looking for compiler 'gcc' ...
... Executing command 'which gcc' ...Yes ('/usr/bin/gcc').

Found installed compiler 'gcc'.
