First, there's no reason to split up the compile and link step. Do it
in one step unless you know that you need to do otherwise. You'll generally
have less trouble. BTW, you can skip '-lc' as well. You get this by
default. That's true for '-lm' too.
So now you know you have undefined references. Check the objects/libraries
that you're using and see if those symbols are in there. If not, go looking
for the objects/libraries that do contain those symbols. If you find the
symbols but they look a little different (maybe they have @<some number> at
the end), then look up information about calling conventions at
msdn.microsoft.com. The information there should allow you to bridge the
gap.
Good luck,
Larry
