Warnings - L1823

[Taig]

 hi!

 I have some problem.

 I use freescale CodeWarrior IDE version 5.9.0

This is my problem.

I'd appreciate any help

it means that you have referenced/used variables, but not defined them.

E.g.  in input.c, you use a variable 'l_keyin' which has no allocated memory.

so you need to add somewhere something like

char l_keyin;

(you might need to use another type instead of char).

The linker detects this, and creates a default object for you. But really you should have defined that object in your code.
