2015-09-15 15:06:12 -0600	commented question	OpenCV Unspecified error - cvShowImage Strange! I followed your advice and I tried to recompile with 2.1 instead of 3.2 but I got this error: [ 1%] Building NVCC (Device) object modules/core/CMakeFiles/cuda_compile.dir/__/dynamicuda/src/cuda/./cuda_compile_generated_matrix_operations.cu.o nvcc fatal : Unsupported gpu architecture 'compute_21' CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:208 (message): Error generating /home/brian/opencv/release/modules/core/CMakeFiles/cuda_compile.dir/__/dynamicuda/src/cuda/./cuda_compile_generated_matrix_operations.cu.o. Thank you
2015-09-15 08:57:53 -0600	asked a question	OpenCV Error: Null pointer (NULL guiReceiver (please create a window)) Under Ubuntu 15.04 I am trying to compile in QTCreator an application that uses OpenCV and CUDA to display Intel DepthSense 3D camera. But I suspect that when the window with camera frame attempts to appear the following error occurs: `OpenCV Error: Null pointer (NULL guiReceiver (please create a window)) in cvDestroyWindow, file /home/brian/opencv/modules/highgui/src/window_QT.cpp, line 497 terminate called after throwing an instance of 'cv::Exception' what(): /home/brian/opencv/modules/highgui/src/window_QT.cpp:497: error: (-27) NULL guiReceiver (please create a window) in function cvDestroyWindow The program has unexpectedly finished. /home/brian/Scherady/build-htrack-Desktop-Default/htrack_atb crashed'.` Any help? Thank you.
2015-09-14 14:59:45 -0600	commented question	OpenCV Unspecified error - cvShowImage I had used -D CUDA_ARCH_BIN=3.2 -D CUDA_ARCH_PTX=3.2 as I had seen in another forum, is it a problem, even if it compiled OK? Now I have another error: OpenCV Error: Null pointer (NULL guiReceiver (please create a window)) in cvDestroyWindow, file /home/brian/opencv/modules/highgui/src/window_QT.cpp, line 497 terminate called after throwing an instance of 'cv::Exception' what(): /home/brian/opencv/modules/highgui/src/window_QT.cpp:497: error: (-27) NULL guiReceiver (please create a window) in function cvDestroyWindow The program has unexpectedly finished. /home/brian/Scherady/build-htrack-Desktop-Default/htrack_atb crashed' Thank you.
