rcnn_build fails

[tdiethe]

When I try to run rcnn_build(); I get the following errors:

> In rcnn_build (line 8)

Error in rcnn_build (line 8)
  mex -outdir . ...

All of the other toolboxes compile fine, and every step up to this point was fine. Any idea what's going on here?

See if Issue #2 helps.

Ok I tried following your Oct 15 instructions, but when trying to do step 2 (make inside the liblinear-1.4/matlab directory) I get the following:

/usr/local/MATLAB/R2015a/bin/mex CC#g++ CXX#g++ CFLAGS#"-Wall -Wconversion
-O3 -fPIC -I/usr/local/MATLAB/R2015a/extern/include -I.." CXXFLAGS#"-Wall
-Wconversion -O3 -fPIC -I/usr/local/MATLAB/R2015a/extern/include -I.."
-largeArrayDims train.c ../tron.o ../linear.o linear_model_matlab.o
../blas/blas.a

~/rcnn-depth/eccv14-code/rcnn/external/liblinear-1.94/matlab/CC#g++ not
found; check that you are in the correct current folder, and check the
spelling of
'~/rcnn-depth/eccv14-code/rcnn/external/liblinear-1.94/matlab/CC#g++'.

make: *** [train.mexa64] Error 255

That CC#g++ looks like an error doesn't it?
