pkg 配置中的错误

Question

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. sudo 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 导出 PKG_CONFIG_PATH

然后我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

Package opencv was not found in the pkg-config search path.

Answer 1

要将正确的路径添加到您的 bashrc，您可以执行以下步骤

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