Problem with libraries during make

[sbarrufaldi]

I tried to install bgslibrary as it shows on README: Ubuntu / OS X installation.

I cloned repository. OK Ran cd build and cmake .. OK When I ran make for first time it showed this:

/home/pi/bgslibrary/package_bgs/IBGS.h:23:16: fatal error: cv.h: No existe el fichero o el directorio #include <cv.h>

(Sorry, I got it in spanish!)

... then have modified the file IBGS.h with the route to cv.h (I think was the right) file and it started to work, but then showed this:

I tried to #include (route to cv modules) in IBGS.h but it doesn't works.

Anyone can help?

Hello @sbarrufaldi , I am sorry for my delayed feedback, I think this error:

/home/pi/bgslibrary/package_bgs/IBGS.h:23:16: fatal error: cv.h: No existe el fichero o el directorio
#include <cv.h>

was solved in my last commit https://github.com/andrewssobral/bgslibrary/commit/4aca9a30f89f40cf17dad1aa2e712bdfb55b2ac2

Can you test and validade if this error still occurs in the latest version of the master branch? Thanks in advance, Andrews

It still present, any result from investigation please ! @andrewssobral ................................................. UPDATE ................................................ it seems to have big conflict opencv4, many function in opencv4 their names changed since opencv3

@andrewssobral Indeed, Andrews Sobral, it seems bgslibrary 2.0.0 conflicts against OpenCV4 ...
