Undefined function 'mex_contour_sides' for input arguments of type 'double'

Hello, following the steps in Readme and when running demo.m this problem arises:

runname =

release

Time taken for computing ng at scale 1: 5.525.

Time taken for computing ng at scale 2: 2.891. Undefined function 'mex_contour_sides' for input arguments of type 'double'.

Error in demo (line 6) run_all(I, D, RD, C, out_file);

I don't know where it is possible that the problem exists. How can I figure it out? Many thanks!

Did you build mcg using mcg_build(); as indicated in https://github.com/s-gupta/rcnn-depth#building? mex_contour_sides is build from https://github.com/s-gupta/rcnn-depth/blob/master/mcg/src/bsr/mex_contour_sides.cpp in mcg_build().

@l-hang @s-gupta I have same issue I built mcg but still got this error any idea?

@l-hang I solve by adding mcg/lib to path... it's strange that I add eccv14-code and its subfolder to path doesn't contatin mcg/lib. Hence I need to manually add it. Now it works.
