Description

It seems that imshow function (and may be larger part of highgui) is broken. It actually doesn't work, and it can be reproduced with any of C/C++ samples. Here is what I have if run the c-example-facedetect with the latest 2.4 branch (b2d1d87ed)

~/Work/OpenCV/build_mac_2.4> ./bin/c-example-facedetect --cascade=../opencv/data/lbpcascades/lbpcascade_frontalface.xml  
...
Capture from CAM 0 didn't work
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /Users/kirill-kornyakov/Work/OpenCV/opencv/modules/highgui/src/window.cpp, line 483
libc++abi.dylib: terminate called throwing an exception
Abort trap: 6

At the same time everything works in the 2.4.6 release. But with the 2.4.6.1 release I don't see the window, but only a small piece of it. And again, in the latest version nothing works...

So, it seems we have some regression here. I'm going to check Git log and try to understand what went wrong.

Fixed in the current 2.4 branch, it was something with CMake files (elif instead of elseif).
