I am trying to install YOLOV4 in Linux and when I run make.I get this error: lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line. Maybe the problem is related the dynamic or static link, and also know that plusing "-ldl" can solve the problem. However,I am a linux freshman, and i don't where i would plus it or solve this error.

What can I do to fix this?Thank you very much!

I attach the display in terminal.
