pkg-config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"opencv.pc"文件。然后输入以下两个命令：

1. sudo gedit /etc/bash.bashrc

将以下两行添加到“bash.bashrc”文件并保存该文件：

然后，在输入以下命令后，我得到了以下错误：

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.

to the PKG_CONFIG_PATH environment variable
No package 'opencv' found

Answer 1

要向bashrc添加正确的路径，可以执行以下步骤

1. 数独查找/ -name "opencv.pc“-type f
2. 请注意来自1的目录输出(没有文件名)
3. 打开/etc/bash.bashrc sudo vi /etc/bash/bash.bashrc
4. 查找、编辑或添加以下行 PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/your/path/from/#1 导出PKG_CONFIG_PATH
5. 保存您的文件:wq
6. 退出并再次登录以激活更改
