I have cross compiled OpenCV application(removeRedEye) statically for RISCV architecture,now i am executing application in riscv-linux root file system,but when i am executing executable i am getting errors.Please help me in this.

Error:--

/removeRedEyes

/removeRedEyes terminate called after throwing an instance of 'cv::Exception' what(): OpenCV(3.4.2) /home/billa/Downloads/opencv-3.4.2/modules/highgui/src/window.cpp:698: error: (-2: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 function 'cvWaitKey'

since you did not compile in any gui support (e.g. from gtk or qt), you cannot use any opencv gui functions, like imshow(), namedWindow(), waitKey()

IF you need any gui, you either have to find a prebuild risc gtk or qt package, or cross-compile it from src.

(then rerun cmake & rebuild the opencv libs)

By using this command i am cross compiling Opencv library
cmake -DCMAKE_TOOLCHAIN_FILE=../riscv.toolchain.cmake ../../.. -DWITH_PNG=OFF -DBUILD_SHARED_LIBS=OFF -DBUILD_ZLIB=ON -DBUILD_opencv_dnn=OFF -DBUILD_EXAMPLES=ON -DWITH_OPENEXR=OFF -DWITH_GTK_2_X=ON -DWITH_QT=ON -DCMAKE_EXE_LINKER_FLAGS="-static" and after that i have cross compiled Opencv Application and finally i am running executable in riscv linux i am getting Error like this way
