RTX51 TINY: Error L104 (Multiple Public Definitions) of MAIN

Information in this article applies to:

• C51 All Versions

QUESTION

I have created my first RTX51 Tiny program. But, when I compile and link I receive the following error message:

*** ERROR L104: MULTIPLE PUBLIC DEFINITIONS
    SYMBOL:  MAIN
    MODULE:  C:\KEIL\C51\LIB\RTX51TNY.LIB (?RTX51_TINY)

What does this mean?

ANSWER

RTX51 Tiny has its own main C function so you must not include one in your project. Instead, the first function in your program that executes is the task 0 task.

To resolve the linker error move the code in your main C function into the task 0 task.
