Caffe MATLAB Interface Configuration

Reference blog: Http://blog.csdn.net/thystar/article/details/50720691caffe only supports gcc-4.7 in MATLAB, but ubuntu14.04 installs gcc-4.8 by default.

Select Install gcc-4.7 and downgrade as follows:

Download and install gcc-4.7 and g++-4.71

sudo apt-get install gcc-4.72

sudo apt-get install g++-4.7

Linking gcc-4.7 and g++-4.7 for demotion

1 Cd/usr/bin

2 sudo rm gcc

3 sudo ln-s gcc-4.7 gcc

4 sudo rm g++

5 sudo ln-s g++-4.7 g++

6 # See if you are connected to 4.7.x

7 Ls–al gcc g++

8 gcc--version

9 g++--version

After the installation, you need to modify the caffe\makefile.config inside the MATLAB path.

Matlab_dir: =/usr/local/matlab/r2013b

Save and recompile

1 sudo make clean
2 make all
3 make test
4 make runtest
5 make Matcaffe

May appear:

Makefile:518:recipe for Target ' matlab/+caffe/private/caffe_.mexa64 ' failed

Make: * * * [matlab/+caffe/private/caffe_.mexa64] Error 255

Workaround:

In makefile, about the No. 410 line that sentence cxxflags + =-mmd-mp Add cxxflags + =-std=c++11 below, and finally this
Cxxflags + =-mmd-mp
Cxxflags + =-std=c++11
Then make Clean,make all in the Caffe root directory
