Matlab (R2015b) Compilation of Caffe-0.999

[deeptigp]

Hi,

I've successfully installed Caffe in $RCNN/external/caffe . However, when I run make matcaffe, I get the below error:

/usr/local/MATLAB/R2015b/bin/mex matlab/caffe/matcaffe.cpp build/lib/libcaffe.a
CXXFLAGS="$CXXFLAGS -pthread -fPIC -DNDEBUG -O2 -I/usr/include/python2.7 -I/usr/lib/python2.7/dist-packages/numpy/core/include -I/usr/local/include -Ibuild/src -I./src -I./include -I/usr/local/cuda/include -Wall"
CXXLIBS="$CXXLIBS -L/usr/lib -L/usr/local/lib -L/usr/lib -L/usr/local/cuda/lib64 -L/usr/local/cuda/lib -lcudart -lcublas -lcurand -lpthread -lglog -lprotobuf -lleveldb -lsnappy -lboost_system -lhdf5_hl -lhdf5 -lopencv_core -lopencv_highgui -lopencv_imgproc -lopenblas" -o matlab/caffe/caffe.mexa64
Unknown MEX argument '-o'.
make: *** [matlab/caffe/caffe.mexa64] Error 255

I am using Ubuntu 14.04 and Matlab R2015b. My LD_LIBRARY_PATH includes path to cuda.

export LD_LIBRARY_PATH=/usr/local:/usr/local/cuda-7.5/lib64:/usr/lib/nvidia-352:

Is this issue because of my Matlab version and Caffe-0.999? I was able to successfully compile the latest version of Caffe (obtained from https://github.com/BVLC/caffe)

Any help would be appreciated. Thanks!

Hi deeptigp,

I had the same problem with Matlab R2014a, our versions seem to updated for caffe 0.999. I fixed the problem by changing the Makefile like this:

change the line $(MATLAB_DIR)/bin/mex $(MAT$(PROJECT)_SRC) $(STATIC_NAME)
with $(MATLAB_DIR)/bin/mex $(MAT$(PROJECT)_SRC)
this remains the same: CXXFLAGS="$$CXXFLAGS $(MATLAB_CXXFLAGS)"
change CXXLIBS="$$CXXLIBS $(LDFLAGS)" -o $@
with CXXLIBS="$$CXXLIBS $(STATIC_NAME) $(LDFLAGS)" -output $@

Hi, @deeptigp

I had the same problem with Matlab R2014b, Linux 14.04, caffe v0.999. I fixed the problem by changing the Makefile like this,

change CXXLIBS="$$CXXLIBS $(LDFLAGS)" -o $@
to CXXLIBS="$$CXXLIBS $(STATIC_NAME) $(LDFLAGS)" -output $@

which meaning add $(STATIC_NAME) before $(LDFLAGS) and change -o to -output

It works for me!
