Cmake Errors

asked 2017-05-10 12:41:21 -0500

Hi guys, I'm using CMAKE-GUI to configure and generate the files for installing OPENCV and link it with my Qt 5.8. I'm doing it on a Ubuntu 16.04 system, using opencv 3.2.0 and opencv_contrib 3.2.0

Apparently I'm having several errors related to the opencv_contrib usage. I've already Configurate OPENCV using CMAKE-GUI, without the CONTRIB modules and everything went all right. But I've tried to add the contrib modules a few times and was never able to do it. So, I've uninstalled everything and I'm doing it from the scratch.

I'm still having several errors and I didn't find any help to them so far. I'll be linking the several errors below.

Is necessary to remove this from includes. I use OpenCV 3.1 and I removed it and now all is well :D That's my solution. For me was a good solution :D @anhnamxtanh

Thanks for the answer. In fact, I've downloaded protobuff from their github, but now I'm with errors on other downloads. It seems that my cmake+opencv cannot download dependencies. Anyway, I'll be unchecking all unnecessary modules from contrib.
