Thank you for your work. Some error happened when MAKE Opencv 4.8.0 in Ubuntu 22.04 as the code saying.

Seems like your linker cannot find the CURL symbols. Have you tried sudo apt install curl libcurl4-openssl-dev, or linking -lcurl manually?

Thanks for your reply. I did some try aboyt sudo apt install libcurl4-openssl-dev,but not sudo apt install curl libcurl4-openssl-dev, your advice worked! Problems Solved
