Compilation Error: libDAI-0.3.2 in Ubuntu 14.04 with MATLAB

I am trying to install libDAI-0.3.2 in Ubuntu 14.04. I need to use it with MATLAB.

I made following changes :

1. In Makefile.conf:

   CC=g++-4.7

   MEXFLAGS:=CXX=#$(CC) CXXFLAGS#'$(CCFLAGS)'

2. In Makefile.ALL: WITH_MATLAB=true

3. Since default compiler in Ubuntu 14.04 is gcc 4.8.4, I installed gcc-4.7 and g++4.7.

Still I get the following compilation error:

    libDAI-0.3.2$ make
    /usr/local/MATLAB/R2015a/bin/mex -Iinclude CXX= -largeArrayDims  -lgmpxx -lgmp  -output matlab/dai.mexa64 src/matlab/dai.cpp src/matlab/matlab.cpp src/graph.cpp src/dag.cpp src/bipgraph.cpp src/varset.cpp src/daialg.cpp src/alldai.cpp src/clustergraph.cpp src/factor.cpp src/factorgraph.cpp src/properties.cpp src/regiongraph.cpp src/cobwebgraph.cpp src/util.cpp src/weightedgraph.cpp src/exceptions.cpp src/exactinf.cpp src/evidence.cpp src/emalg.cpp src/io.cpp src/bp.cpp src/fbp.cpp src/trwbp.cpp src/mf.cpp src/hak.cpp src/lc.cpp src/treeep.cpp src/jtree.cpp src/mr.cpp src/gibbs.cpp src/bbp.cpp src/cbp.cpp src/bp_dual.cpp src/decmap.cpp src/glc.cpp

     /tmp/mex_11282758003780_5023: -c: not found

make: *** [matlab/dai.mexa64] Error 255

what does this mean? Any idea how to fix this?

Thanks & Regards, Swagatika

Try replacing

MEXFLAGS:=CXX=#$(CC) CXXFLAGS#'$(CCFLAGS)'

with

MEXFLAGS:=CXX=$(CC) CXXFLAGS='$(CCFLAGS)'
