As a beginner, I download a small source code to start my study.
The code is implemented based on OpenCL1.1 while my version is OpenCL1.2, so I have to change some codes.
When I wrote the following codes to create a 2D image, the program crashed.
...........................
// Create OpenCL image
cl_image_format clImageFormat;
clImageFormat.image_channel_order = CL_RGBA;
clImageFormat.image_channel_data_type = CL_UNORM_INT8;
cl_image_desc clImageDesc;
clImageDesc.image_type = CL_MEM_OBJECT_IMAGE2D;
clImageDesc.image_width = width; //100
clImageDesc.image_height = height; //100
clImageDesc.image_array_size = 1;
clImageDesc.image_depth = 0;
clImageDesc.image_row_pitch = width*4; //rgba mode, that is 400 bytes
clImageDesc.image_slice_pitch = height;
clImageDesc.num_mip_levels = 0;
clImageDesc.num_samples = 0;
clImageDesc.buffer = NULL;
clImage = clCreateImage(context, CL_MEM_READ_ONLY | CL_MEM_COPY_HOST_PTR, &clImageFormat, &clImageDesc, buffer, &errNum);

Thank you for your help~
