使用 OpenCV 库编译代码时出现链接错误
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.
