Well, the only thing I can figure is that when you use the -I and -L options,
you may not be including the entire path to the appropriate directories.

If you want to be REALLY sure you get them right, you need to enter the
whole thing.  I usually use the IDE, but do experiment with TCC sometimes.
I enter:

           tcc -Id:\lang\tc\include -Ld:\lang\tc\lib foo.c

Now you know why MAKE is so nice!

Another problem you could be having is not linking in the right libraries
when you link.  If you are using the small model, you need some crap like

           link foo.obj+d:\lang\tc\lib\c0s.lib+d:\lang\tc\lib\graphics.lib /
                       +d:\lang\tc\lib\cs.obj

and so on and so forth.  I noticed you mentioned setcolor.  Make sure you
link in the graphics library!  

I told you all this from memory, so there are holes.  But experiment, and by
all means KEEP LOOKING AT THE MANUALS.  Even with the manuals, it takes time
to fully understand it all!

Me... I just use the IDE!  :-)

PS- And by all means... LEARN HOW TO USE MAKE!!  It's a MUST so you don't have
    keep typing all those LONG lines!
