Sorry, my memory of MathLib is a little foggy, but aren't you supposed
to compile with a MathLib.c source file, to set up the library calls?
If you neglected that, it would explain your problem.
Are you using CodeWarrior or PODS? If PODS, you need to add the .c
file to your source code directory, then do a Refresh from the
right-click popup menu in the Navigator window on the left side of
the IDE window. (Right-click on your project's name, select Refresh,
then Project->Clean...)
Oh, and check the return values of your system calls, too. ;-)
