BL51: WARNING L1 (UNRESOLVED EXTERNAL SYMBOL)


Information in this article applies to:

  • C51 Version 6.10a

SYMPTOMS

After installing the C51 V6.10a update, I receive one of the following error messages when I link my program:

WARNING L1: UNRESOLVED EXTERNAL SYSMBOL
SYMBOL:    ?C?COPY517
WARNING L1: UNRESOLVED EXTERNAL SYSMBOL
SYMBOL:    ?C?COPYAMD
WARNING L1: UNRESOLVED EXTERNAL SYSMBOL
SYMBOL:    ?C?COPYP2

CAUSE

This problem is caused when updating your software from a prior release of V6.x to the latest 6.10a. Typically, this is caused by installing the software 2 times (first as the evaluation version and second as the full update).

RESOLUTION

To rectify the problem, uninstall the software and re-install it from the V6.10a update. Then, you will have the correct libraries.
