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“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”文件中并保存文件： 的 PKG_CONFIG_PATH = $ PKG_CONFIG_PATH：/home/pi/Opencv-2.4.3/release/lib/pkgconfig 导出PKG_CONFIG_PATH

然后在输入这些命令后出现以下错误：

1. chmod + x build_all.sh

2. /build_all.sh

解决方案是什么？

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.

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.（无文件名）
的目录输出
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：/你的/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
