Cannot compile GECKO about gecko HOT 4 OPEN

I have tried to compile it with @JuanFdelArco today, and the main errors were:

• ColorDebug has to be downloaded, maybe we should use superbuild instead of git submodules.
• Haar cascades template file is hardcoded, resulting in errors when the location of the file changes (due to differences in the OpenCV installation). This does not cause a compilation error, but a runtime error.

from gecko.

I cloned ColorDebug and put the source in external/ folder. I then tried to build and this is the following error :

Could this be because I am using OpenCV 3.2? Would really love to try out/contribute to Gecko!

Hi @crearo !

I've been taking a look to the docs for OpenCV 3.2 and it seems that the related API for the background subtractor we use in Gecko has changed. In summary, the background subtractor creation is now done differenty, and our approach is no longer valid, so Gecko doesn't not work with OpenCV 3.2.

Is there any reason to use OpenCV 3.2? Could you try with the older 2.x version?

from gecko.

The reason I use OpenCV 3.2 is because of the Java wrappers that come with it. No worries though, I shall download 2.4.13 version and try to compile once again! I'll post here once I do.

Edit : Compiled successfully!
