it seems to turn out that you have zero knowledge about compiling at
all, and dont even understand what we all explained to you.
Since your probs will occure with any other external library usage I
suggest that you start learning how compilation and linking works, and
if you have questions then first read the manual, second read the
manual, and third read the manual (in your case for gcc and ld /
binutils), and then post your remaining questions in a forum for
beginners. None of your questions really belong here to this list.

Gün.
