在ubuntu下使用cuda支持构建opencv 3.1.0的问题

Question

我使用的是Ubuntu 14.04，使用cuda 8.0构建opencv 3.1.0。

CMake的命令：

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -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=ON -D WITH_OPENGL=ON -D ENABLE_FAST_MATH=1 -D CUDA_FAST_MATH=1 -D WITH_CUBLAS=1 -DOPENCV_EXTRA_MODULES_PATH=/home/lindeyang/library/opencv_contrib/modules .. 

CMake的配置后，我开始建立，但随着问题的失败： “不足CUDA运行时库版本，请更新它。”

任何人都可以帮忙吗？

错误：

林宇阳，

的问题是，你必须安装CUDA的多个版本。 可能当您上次cuda版本升级时，来自其他版本的某些文件仍然保留在您的系统中。

查找使用如下命令库： dconfig -p | grep libcudart

此命令显示您机器上的libcudart版本。但删除旧的库并不能解决你的问题。由于CUDART_VERSION小于所需（CUDART_MINIMUM_REQUIRED_VERSION）下 /opencv/modules/core/include/opencv2/core/private.cuda.hpp ：

的问题发生在文件中。

搜索放在/ usr /为： grep --include=\*.{c,cpp,h,hpp} -rnw '/usr/' -e "define CUDART_VERSION"

也许你会发现在/ usr /本地/ CUDA实际版本/和一些包含文件在/ usr/include中/： 在这个文件： /usr/include/cuda_runtime_api.h 您找到了错误的版本。

我解决了这个问题，比较文件夹并用新的（/ usr/local/cuda/include /）覆盖旧的cuda头文件（/ usr/include /）。

另一种方法是删除使用apt或NVIDIA安装程序二进制文件（* .RUN）所有版本： sudo apt-get remove --purge nvidia-*

但是，你需要重新安装所有库。
