Question

我正在使用Ubuntu 14.04，使用cuda 8.0构建opencv 3.1.0。

cmake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 ..

在cmake配置之后，我开始构建，但是遇到了问题：＆＃34; Cuda Runtime库版本不足，请更新它。＆＃34;

有人可以帮忙吗？

错误：

杨玉林，

问题是您安装了多个版本的CUDA。可能在您上次cuda版本升级时，另一个版本的某些文件仍保留在您的系统中。

使用以下命令查找libs： dconfig -p | grep libcudart

此命令显示计算机上的libcudart版本。但删除旧的库不能解决您的问题。

问题发生在文件中： /opencv/modules/core/include/opencv2/core/private.cuda.hpp 因为CUDART_VERSION低于要求的值（CUDART_MINIMUM_REQUIRED_VERSION）。

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

您可能会在/ usr / local / cuda /中找到实际版本，并在/ usr / include /中找到一些包含文件：在这个文件中： /usr/include/cuda_runtime_api.h 你找到了错误的版本。

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

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

但是，您需要重新安装所有库。
