使用 OpenCV 库编译代码时出现链接错误

Linking errors when compiling code with OpenCV Libraries(使用 OpenCV 库编译代码时出现链接错误)

问题描述

在使用以下命令安装 Opencv 后，我正在尝试编译示例程序:

I'm trying to compile a sample program after installing Opencv with the command:

g++ hello-world.cpp -o hello-world -I /usr/local/include/opencv -L /usr/local/lib -lm -lcv -lhighgui -lcvaux

但是，我收到一条错误消息:

however, I'm getting an error that says:

/usr/bin/ld: cannot find -lcv  
/usr/bin/ld: cannot find -lhighgui  
/uer/bin/ld: cannot find -lcvaux
collect2: ld returned 1 exit status

我需要做些什么来纠正这个问题?我通过下载最新的稳定版本并使用 cmake 创建构建文件来安装 opencv，然后从命令行运行 make install.

What do I need to do to correct this?? I installed opencv by downloading the latest stable version and using cmake to create the build files, then ran make install from the command line.

有什么我可能遗漏的吗?

Was there anything I may have missed?

推荐答案

您需要添加另一个 -L 参数，指定 OpenCV 库的实际位置.

You need to add another -L argument specifying the actual location of the OpenCV libraries.
