Message

Referenced compatibility library not found

This error occurs when a compatibility library is activated by name — either explicitly with --library <name> or by a project file reference — but no library of that exact name can be found.

Library names are matched strictly and case-sensitively, so that the compiler never silently binds the wrong library. The diagnostic names the missing library so that any resulting undefined symbol errors are explained.

Example

# No library named "Tc2_Maths" exists (note the trailing 's')
ironplcc check --library Tc2_Maths main.st

To fix this error:

• Check the spelling and capitalization of the library name.

• Confirm the library is installed where the compiler looks for libraries.

• Remove the activation if the library is not required.

Think IronPLC is wrong about this?
