ubuntu 编译安装支持CUDA的OpenCV+其他opencv细节(需要特定版本gcc)

安装须知

cuda支持

  • 在安装完“ linux CUDAtoolkit+cudnn+tensorrt 的安装”之后进行支持cuda的opencv安装

  • 否则报错:CMake Error at modules/dnn/CMakeLists.txt:41 (message):
    DNN: CUDA backend requires CUDA Toolkit. Please resolve dependency or
    disable OPENCV_DNN_CUDA=OFF

在这里插入图片描述- $ nvcc -v -----> Command 'nvcc' not found, but can be installed with: sudo apt install nvidia-cuda-toolkit

install 特定版本gcc

  • sudo apt remove gcc
  • sudo apt purge gcc # 除了可以删除安装包之外,还可以清除相关的配置文件。

-D CUDNN_INCLUDE_DIR=/usr/local/cuda/include  \
-D CUDA_CUDA_LIBRARY=/usr/local/cuda/lib64/stubs/libcuda.so \
  • 且最好不要把所有版本都编译,如CUDA_ARCH_BIN=“3.0 3.5 3.7 5.0 5.2 6.0 6.1 7.0 7.5 8.6”
    最好根据上面的说明,查一下当前显卡的型号,以及对应的显卡算力,然后在这里指定一个即可,如3060显卡可以保持 CUDA_ARCH_BIN=“8.6”。否则全部编译一遍速度会很慢。

  • …/—指定根CMakeList.txt文件路径,在opencv-4.2.0根目录(…/表示上一级)

  • sudo vim /etc/ld.so.conf.d/opencv.conf
    在这里插入图片描述

  • vim ~/.bashrc

CG

  • windows version :opencv c++ Mat CUDA的编译与使用

  • i found that after i remove my gcc and do this sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg.dev libtiff5.dev libswscale-dev libjasper-dev,i will get a new gcc and dont need do anything else.

  • 好消息,现阶段opencv在cmake配置的时候加上-DOPENCV_DOWNLOAD_MIRROR_ID=gitcode,可以使用gitee国内镜像下载依赖了 -DOPENCV_DOWNLOAD_MIRROR_ID=gitcode

  • 在Linux上编译带CUDA(GPU)的OpenCV
