HI, there the author states that compiling opencv 3.1.0 using gcc and g++ 4.9+ fails, but it is not true. I build it using version 5.3 on Ubuntu 16.04 and it works for me

I turned off CUDA and OPENCL options from build and now it works. I will check again later enabling just one of them because I'm using driver 340.96 from Nvidia.

Includes are fine and links are already configured to 3.1.0 .so files

2016-03-21 01:46:41 -0600 asked a question opencv 3.1 hangs on some functions

Hi, I don't know where to start, the matter is that when I use simple functions like cv::cvtColor or cv::split, the program simply hangs, not breaks or terminates, leaving defunct processes. I'm using Ubuntu 14.04.3 and tried several installations of opencv 3.0.0, 3.1.0 and master branch of repo. Someone have any idea why this happens? Perhaps some missing build configuration?

EDIT 1 VideoCapture and ImRead works fine, also displaying images and videos work as well, but when I want to add simple processing, the programs stop.

EDIT 2 Some examples of code that does not work are found in Histogram Equalization tutorial and Histogram Calculation tutorial

EDIT 3 Tried the same code in Gnome Ubuntu 16.04 and OpenCV 3.1 on a Virtual Machine and works fine.
