  • C51 Version 6.10a

SYMPTOMS

When I link my program, I receive the following linker error:

FATAL ERROR L251: RESTRICTED MODULE IN LIBRARY NOT SUPPORTED
MODULE: xxxxx (yyyyy)

What does this mean and how can I fix it?

CAUSE

This error indicates that one of the modules (yyyyy) in the library xxxxx was compiled or assembled using a restricted version of the Keil tools.

The restricted tools are only distributed with the FREE evaluation software. So, usually, this indicates that the library was built using an evaluation tool set.
