error in running demo: Error in jointBilateral

[hojat-kaveh]

I've completed installing "rcnn-depth" according to help on Ubuntu 16.04.4 (gcc 5.4.0) except the step that I have to run rcnn_build(); witch resulted in error and as suggested in issue #2 I run make in liblinear-1.94 and `liblinear-1.94/matlab' folders.

I've tried with both Matlab R2016b and Matlab R2012b (with editing matlab path in imagestack Makefile and liblinear-1.94/matlab Makefile), both produce this error:

result of Matlab R2012b: runname =

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

what is GLIBCXX_3.4.21? what is causing this error?

This is probably because the libraries that you used to compiled imagestack with are different from the one that matlab has loaded. You could try specifying LD_PRELOAD path (to point to the system libraries that were used to compile imagestack) while launching matlab to fix this.

[hojat-kaveh]

I used instruction in here and after a clean make of imagestack and liblinear-1.94 and liblinear-1.94/matlab, executed this: LD_PRELOAD="/usr/lib/x86_64-linux-gnu/libstdc++.so.6" mymatlab_2016b

running demo() leads to the same error as before! :( Can creating a symbolic link of the system libraries (like here)fix this?

[hojat-kaveh]

Ok, creating the symbolic link seems to do the trick! I finally managed to run the demo! YAY!
