Mex (Matlab 2015a) - error "no supported compiler or SDK was found"

Dear supporters,

I am using Matlab 2015a on the Ubuntu 14.10 When i execute the following command "/usr/local/Matlab2015a/bin/mex -cxx CXX=g++4.7 CC=g++4.7 LD=g++4.7 -lm -O -output A.mexa64 A.o B.o C.o"

I have received the following error "no supported compiler or SDK was found."

Hope to receive your support on this problem.

Best regard Vu The Huynh

Are you missing a hyphen between g++ and the version number? In other words, try using "g++-4.7" instead of "g++4.7". Also, please try the resolution given in the following link which explains how to adjust "mexopts.sh" to use a supported compiler:

Dear supporter,

Thank for your reply. I have found the asnwer. I am not missing a hyphen. After i install g++-47, i haven't changed the default compiler.

After changing the default by the following command "sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.7", i was able to resolve the issue.
