Hello.
I Built opencv 3.0 master branch from source using cmake and visual studio 2013 community version. Aditional support was enabled for CUDA and VTK. Everything built fine, but when I call function imshow(), I get following error in console: opencv error: Unspecified error (function ins not implemented. Rebuild the library with windows, GTK+ 2.x or Carbon support)....
It seems that it has something to do with window UI framework. In cmake configuration Win32UI option was selected and no errors appeared while building
thanks.
