Compiling error

[bcatalin]

I am trying to compile an application where I am using time functions but I am receiving the following error:

there are some undefined references in libc ? Compiling just my libuser.a is fine.

hi
not sure, but a try..
btw, have you add your libuser.a?
think you have a little mistake in 'user' there is missing -l
try again edit your makefile with -luser
and let know, how you get on in this.

best wishes
