Unsupported gpu architecture 'compute_11'解决方法

环境背景:

由于项目需要，在ubuntu service 14.04 下搭建 OpenCL +OpenCV 环境， 前期安装了 CUDA7.0 ，GPU为 NVIDIA TITAN 。

问题描述：

按照网上教程安装OpenCV ，在make 时出现错误，错误提示如下:

nvcc fatal   : Unsupported gpu architecture 'compute_11'
CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:206 (message):

解决方法:

百度无果，求助万能谷歌。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 ..

然后，这个问题就奇迹般的解决了。

总结:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON
-D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=OFF -D WITH_OPENGL=ON -D BUILD_TIFF=ON ..

This let me install opencv-2.4.9.

另外一种解决方案:

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.
