Subject:	static linked libgd

Hi,

i am new to GD and also to C. I am trying to write a small programm that 
manipulates an image by adding some text and some simple drawings. The 
programm will be used on several computers, so i try to link all the 
libs statically.

When i try to compile my test program with

gcc lines2jpg.c -lgd -ljpeg -static

the compiler says

I also included <math.h> but the result is the same. Any help is apreciated!

Thanks, Yann
