Hi,
I am trying to build my Open CV library with eclipse IDE. For building I used- Cmake- 3.13.0 rc2 , mingw-w64, Windows 10, Eclipse IDE-C++, OpenCV-3.4.2
I am getting the following error:-
D:\opencv-3.4.2\opencv\sources\modules\videoio\src\cap_dshow.cpp:2341:31: warning: right operand of comma operator has no effect [-Wunused-value] else sprintf(tmpStr, "%u",prop); ^~~~ mingw32-make[2]: * [modules\videoio\CMakeFiles\opencv_videoio.dir\build.make:175: modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_dshow.cpp.obj] Error 1 mingw32-make[2]: Leaving directory 'D:/opencv-3.4.2/opencv/release' mingw32-make[1]: [CMakeFiles\Makefile2:5076: modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2 mingw32-make[1]: Leaving directory 'D:/opencv-3.4.2/opencv/release' mingw32-make: ** [Makefile:162: all] Error 2
my Cmake confuguration are :-
