c - 我已经安装了 Cuda 6.5，但 OpenCV 给出了有关 Cuda 6.0 的错误

Question

我有 CUDA 6.0 和 OpenCV 2.4.8(用 CUDA 编译)，我用它来了解它，然后我买了一个 Jetson TK-1。 NVIDIA 为 Tegra K1 发布了 R21.2 驱动包和 CUDA 6.5，我已经安装了 CUDA 6.5 并使用 CUDA 样本进行了测试，它们运行没有问题。之后我删除了 CUDA 6.0，样本仍在运行。我也安装了 OpenCV 的新版本 2.4.9，但我没有删除 2.4.8 共享库和 header 。我已经使用 ./build_all.sh 编译了所有 C 示例，所有这些都编译无误，但是当我想在 ../samples/c 目录中运行任何示例时示例 sudo ./contours 我遇到的问题是 ./contours:加载共享库时出错:libcudart.so.6.0:无法打开共享对象文件:没有这样的文件或目录 但当我检查 LD_LIBRARY_PATH 或 PATH 或 opencv.cv 文件和 PKG_CONFIG_PATH (这是对于正确的 opencv.cv 路径)我看不出有任何问题。我正在添加每个路径变量的 echo 输出；

echo $LD_LIBRARY_PATH
:/usr/local/cuda-6.5/lib:/usr/local/cuda-6.5/lib64:/usr/local/opencv-2.4.9/lib
echo $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/CodeSourcery/arm-2013.11/bin:/opt/STLink/stlink:/opt/R-Pi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin:/opt/CodeSourcery/arm-2013.11/bin:/usr/local/cuda-6.5/bin:/usr/local/cuda/bin
echo $PKG_CONFIG_PATH
/usr/local/opencv-2.4.9/lib/pkgconfig

Answer 1

为了安全，在 libcudart.so.6.5 和 libcudart.so.6.0 之间创建一个符号链接(symbolic link)。

sudo ln -s/usr/local/cuda/lib64/libcudart.so.6.5/usr/local/cuda/lib64/libcudart.so.6.0
