I was trying to build opencv to use in Code::Blocks following this guide: link: While building, I got the following error. How to proceed?

[ 39%] Building RC object modules/videoio/CMakeFiles/opencv_videoio.dir/vs_version.rc.obj

your tutorial is far too outdated, to be useful (please do not go there again.)

for now, try to disable precompiled headers in cmake, clean your build folder, and rerun cmake

(there's no more real support for mingw, there will be more errors.)

Thank you very much,this will save me some time. If there is no more support for mingw, what other should I use to correctly build opencv? The Windows release pack isn't working for Code::Blocks

use vs2015, or suffer pain (like me...)

Seems like the only choice... I would rather use linux, but I have some libraries built for windows that would be a pain to open in ubuntu. Thanks again, man
