The Qt backend directly calls some OpenGL functions (glClear, glHint, glViewport), but since OCV 4.5.5 the GL libraries are no longer part of the global extra dependencies. When linking with "-Wl,--no-undefined" this causes linker errors: `opencv-4.5.5/modules/highgui/src/window_QT.cpp:3307: undefined reference to `glClear'` Fixes: #21346 Related issues: #21299 |
