pkg-config出错

Question

我在Rpi上安装了Debian OS.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 export PKG_CONFIG_PATH

然后在输入以下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

要为bashrc添加正确的路径,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 sudo vi /etc/bash/bash.bashrc

4. 查找并编辑或添加以下行

   PKG_CONFIG_PATH = $ PKG_CONFIG_PATH:/你/路径/从/#1

   导出PKG_CONFIG_PATH

5. 保存文件:wq

6. 注销并再次登录以激活更改
