$ Path: determines which directories The shell will look for commands or programs. The path value is a series of directories. When you run a program, Linux searches for compilation links under these directories. Edit your path declaration in the

Similar to the dynamic link library in windows, Linux also has a shared library to support code reuse. *. Dll in windows and *. So in Linux. I will detail how to write a dynamic library in Linux and how to use it. InLinuxTo write a dynamic link
