Under Ubuntu 15.04 I am getting the following error:

****************************************
OpenCV Error: 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 cvShowImage, file /home/brian/opencv/modules/highgui/src/window.cpp, line 501
terminate called after throwing an instance of 'cv::Exception'
  what():  /home/brian/opencv/modules/highgui/src/window.cpp:501: error: (-2) 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 cvShowImage

I have re-installed libgtk2.0-dev and pkg-config and re-run cmake but it did not help.

Any idea what could be the problem?

Thank you

"I have re-installed libgtk2.0-dev and pkg-config and re-run cmake but it did not help." - well, how so ? build errors, cmake output ? you're kinda leaving a huge gap with the current problem.

just to make it clear, the opencv library depends on gtk, not your demo code.

you will have to rebuild the opencv libs (with gtk2 present), not only your project

sorry, can't help with that ;(

You are trying to build a GPU architecture that is not supported by your card. What GPU do you have in your system? Look up your compute capability right here: https://developer.nvidia.com/cuda-gpus

Thank you Steven I have a VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1)

Okay so that card has compute capability 2.1. When you run CMAKE, you specify the following parameters -D CUDA_ARCH_BIN=2.1 -D CUDA_ARCH_PTX=2.1 and the build should work just fine or edit the value in the cmake-gui interface.

  1. 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?
  2. 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.

@Scherady, your GPU card does NOT support the 3.2 architecture, so that is not correct. You need to recompile with the correct CUDA compute compability. As to your second problem, please open up a second question for that and add more information there.

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
