no build possible on RPi4 #9

Closed mk-fs closed 2 years ago

mk-fs commented 2 years ago

The build stops with an error:

error: ‘cvWaitKey’ was not declared in this scope

I installed opencv (libopencv-dev) and BCM2838 Library (V1.71).

Same behaviour at a second new upset RPi4. I need help with this issue.

here the outprint from terminal:

in LePiServer.cpp at line 119, "cvWaitKey()" must be replaced by "cv::waitKey()"
