我在 Rpi 上安装了 Debian 操作系统。在安装 opencv 时，我在 "/home/pi/Opencv-2.4.3/release/lib" 中创建了"opencv.pc"文件。然后我输入了以下两个命令：

  1. 须藤 gedit /etc/bash.bashrc

将以下两行添加到“bash.bashrc”文件并保存文件： PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/pi/Opencv-2.4.3/release/lib/pkgconfig export PKG_CONFIG_PATH

然后输入这些命令后出现以下错误：

  1. chmod +x build_all.sh

  2. /build_all.sh

解决办法是什么？

错误是..

Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found

要将正确的路径添加到 bashrc，您可以执行以下步骤

  1. sudo find / -name "opencv.pc" -type f
  2. 注意1的目录输出。（没有文件名）
  3. 打开 /etc/bash.bashrc须藤 vi /etc/bash/bash.bashrc

  4. 查找并编辑或添加以下行

    PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/your/path/from/#1

    导出 PKG_CONFIG_PATH

  5. 保存你的文件：wq

  6. 注销并再次登录以激活更改
