hi~

when I make mattest, some error happened:

cd matlab; /usr/local/MATLAB/R2014a/bin/matlab -nodisplay -r 'caffe.run_tests(), exit()'

Error in caffe.set_mode_cpu (line 5)

caffe_('set_mode_cpu');

Error in caffe.run_tests (line 6)

caffe.set_mode_cpu();

And my OS is Ubuntu 15.10, so the version of g++ and gcc is 5.2.1. 

what should I do? 

Thanks~

I also encounter the problem , I suggest the gcc version cause the problem ,but apt-cache search gcc just list the version from 4.8 to gcc5, I try each version in my ubuntu 14.10 ,but no one worked. If you solve the problem , please tell me how to fix it.Thank you.

 I am also facing the same problem. My Matlab version is 2015b. I tried to put default version of gcc as gcc-4.7 since Maltab mex support that and explicitly  give gcc version gcc-5 in Makefile configuration for Caffe. 

 

 Anyone able to fix this issue?
