JPEG Libs

Hi thanks for the replies,

I have got libjpeg.la installed in the /usr/lib directory

[ian at localhost ian]$ locate libjpeg.la
/usr/lib/libjpeg.la

And I have added the line into the make file 
$(TARGET):	Main.o Init.o Camera.o Quake3Bsp.o Image.o
	$(CC) -o $(TARGET) Main.o Init.o Camera.o Quake3Bsp.o Image.o `sdl-config 
--libs` -L/usr/X11R6/lib -lGL -lGLU -lm -L/usr/lib -ljpeg 

But I still get the error (at the bottom of the email, same as before)

Or have I done this wrong ?

Cheers
Ian
