Somewhere in your code, you use a function setdate(), which apparently comes
from a library. The code compiles fine since you included the header where
setdate() is declared. However, the header does not provide the definition.
For that reason, the linker needs to include the library. Apparently, the
linker did not know where to look for it. You need to give it a hint. This
is done via linker options. How the mechanism works for your compiler/linker
should be in the documentation that comes with them.

& what is "id" & exit status ..

When programs return, the pass an exit status (an integer) to the calling
environment. That way, a script can check whether a program terminated
successfully or not without analyzing the output. The linker you use exits
with status 1 when it detects an undefined reference.
