I actually managed to launch OpenCV in Code::Blocks somehow, but I have no clue what to do now to run a program. When I make new OpenCV project with such settings as in picture and try to run a default code, it just refuses to do so with errors I copypasted earlier. In search directories, as a compiler I have C:\opencv\buld_cb\install\include\opencv2, and as a linker I have C:\opencv\buld_cb\lib, both in Debug and Realise. I tried to follow manuals, I did this stuff with CMake building (where I had to delete some AVX stuff in GPU_DISPATCH and then completly disable Python features, because it just won't set up in Code::Blocks either way) and MinGW building after that.Ĭ:\TDM-GCC-64\bin, C:\Program Files\TortoiseGit\bin, C:\Program Files\Git\cmd, C:\Program Files\CMake\bin, C:\MinGW\bin, C:\opencv\buld_cb\bin I'm new to OpenCV and to C++ in general so I have almost no clue what to do.
#Code blocks not building and running install
To install the new IDE version, open terminal either by pressing Ctrl+Alt+T on keyboard or by searching for ‘terminal’ from application menu.
