Oninit® Troubleshooting Guidance

Reasons / Common Causes

-21612 fires when an mkmessage input file ends while a preprocessor ^ifdef/^ifndef block is still open — per the official guidance, an ^endif was expected but the file ended first.

  1. The input file ending before a closing ^endif for an open ^ifdef/^ifndef block, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Add the missing ^endif to close the open block, per the official guidance's implication.
Examples
A missing ^endif
^ifdef SOME_MACRO
Some text.
Corrected
^ifdef SOME_MACRO
Some text.
^endif
Diagnostic Checks
  1. Check the input file for an ^ifdef/^ifndef block with no matching ^endif, and add one.

  • -21610 — "Unmatched ^ENDIF at line line-number." The mirror-image condition — an ^ENDIF found with no matching opener, rather than reaching end-of-file with an open block.

The input file ended with an open ^ifdef/^ifndef block — add the missing ^endif.
