Thank you Dane. After I sudo make install, most of the problem gone, but still encounter following error message when make:

what else I might be missing?
my Makefile changes look like this:
ifeq ($(TARGET_DEVICE),aarch64)
PKGS:= gstreamer-1.0 gstreamer-base-1.0 gstreamer-video-1.0
# Add opencv4 to CFLAGS and LIBS
CFLAGS+= -I /usr/local/include/opencv4
LIBS+=-L/usr/local/lib -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_videoio -lopencv_cudafilters
else
PKGS:= gstreamer-1.0 gstreamer-base-1.0 gstreamer-video-1.0 opencv
endif
CFLAGS+=$(shell pkg-config --cflags $(PKGS))
LIBS+=$(shell pkg-config --libs $(PKGS))
My gstdsexample.cpp changes look like this:
#ifdef __aarch64__
/* To use the converted buffer in CUDA, create an EGLImage and then use
* CUDA-EGL interop APIs */
if (USE_EGLIMAGE) {
if (NvBufSurfaceMapEglImage (dsexample->inter_buf, 0) !=0 ) {
goto error;
}
/* dsexample->inter_buf->surfaceList[0].mappedAddr.eglImage
* Use interop APIs cuGraphicsEGLRegisterImage and
* cuGraphicsResourceGetMappedEglFrame to access the buffer in CUDA */
#if 1
static bool create_filter = true;
static cv::Ptr< cv::cuda::Filter > filter;
CUresult status;
CUeglFrame eglFrame;
CUgraphicsResource pResource = NULL;
cudaFree(0);
status = cuGraphicsEGLRegisterImage(&pResource,
dsexample->inter_buf->surfaceList[0].mappedAddr.eglImage,
CU_GRAPHICS_MAP_RESOURCE_FLAGS_NONE);
status = cuGraphicsResourceGetMappedEglFrame(&eglFrame, pResource, 0, 0);
status = cuCtxSynchronize();
if (create_filter) {
filter = cv::cuda::createSobelFilter(CV_8UC4, CV_8UC4, 1, 0, 3, 1, cv::BORDER_DEFAULT);
//filter = cv::cuda::createGaussianFilter(CV_8UC4, CV_8UC4, cv::Size(31,31), 0, 0, cv::BORDER_DEFAULT);
create_filter = false;
}
cv::cuda::GpuMat d_mat(dsexample->processing_height, dsexample->processing_width, CV_8UC4, eglFrame.frame.pPitch[0]);
filter->apply (d_mat, d_mat);
status = cuCtxSynchronize();
status = cuGraphicsUnregisterResource(pResource);
// apply back to the original buffer
transform_params.src_rect = &dst_rect;
transform_params.dst_rect = &src_rect;
NvBufSurfTransform (dsexample->inter_buf, &ip_surf, &transform_params);
#endif
/* Destroy the EGLImage */
NvBufSurfaceUnMapEglImage (dsexample->inter_buf, 0);
}
#endif
Am I change correctly? (by the way what does … in your code mean?) Thank you for your help again.
