How can i link to X11 with gcc?

Hi,
I suppose this question is stupid, but i can not figure it out myself...

How can i link to X11 libraries with gcc ?

if i try to compile with :
"gcc -L/usr/lib -lX11 ..." i recieve the error message :
"cannot find -lX11"

If i change the makefile, so the path is setted, where the libX11.a is :
"gcc -L/usr/X11R6/lib -lX11 ..." i recieve lots of errors like :
"undefined refernce to 'XDrawPoint'"
Most of the listed Functions are includet with Xlib.h (i suppose all, but
they are to many to verify each of them).

Excuseme for my weak english and
thank You;
Oleg
