由於項目需要，在ubuntu service 14.04 下搭建 OpenCL +OpenCV 環境， 前期安裝了 CUDA7.0 ，GPU爲 NVIDIA TITAN 。
問題描述：
按照網上教程安裝OpenCV ，在make 時出現錯誤，錯誤提示如下:
nvcc fatal : Unsupported gpu architecture 'compute_11'
CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:206 (message):

解決方法:
百度無果，求助萬能谷歌。有高人回答如下:
When using cmake to do configurations, set the option CUDA_GENERATION to specific your GPU architecture. I ran across the same error and tried this to work out the problem.
this worked for me and shows a possible value for CUDA_GENERATION:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..
然後，這個問題就奇蹟般的解決了。
總結:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..
- 1
This let me install opencv-2.4.9.
另外一種解決方案:
Another option. Ubuntu 14.04, GTX Titan X, opencv-2.4.10
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_TIFF=ON -D BUILD_EXAMPLES=ON -D CUDA_GENERATION=Auto -D BUILD_NEW_PYTHON_SUPPORT=ON ..
I also applied the patch:
https://github.com/Itseez/opencv/pull/3886/files
but I’m not sure whether it ended up being needed. I had tried with and without >CUDA_GENERATION=Maxwell but Maxwell isn’t detected. I did not try >CUDA_GENERATION=Auto prior to the patch, that’s why I don’t know for sure.
