Informix Error -21610: Unmatched ^ENDIF at line line-number.

Reasons / Common Causes

-21610 fires when an mkmessage input file's preprocessor encounters an ^ENDIF directive with no matching ^ifdef/^ifndef — per the official guidance.

1. An ^ENDIF directive with no preceding matching ^ifdef/^ifndef, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Add the missing ^ifdef/^ifndef, or remove the stray ^ENDIF, per the official guidance's implication.

Examples

An unmatched ^ENDIF

Some text.
^ENDIF

Corrected

^ifdef SOME_MACRO
Some text.
^ENDIF

Diagnostic Checks

1. Check the preprocessor block containing the reported line number for a matching ^ifdef/^ifndef, and add or remove directives to balance it.

Related Errors / Related Topics

• -21609 — "Unmatched ^ELSE at line line-number." The equivalent unmatched-directive error, for ^ELSE rather than ^ENDIF.
• -21612 — "Unexpected EOF. Expected an ^endif." The mirror-image condition — the file ended while still expecting an ^ENDIF, rather than finding an unmatched one.
• -21613 — "Syntax error at line line-number. Expect ifdef, ifndef, else or endif." A related preprocessor syntax error, general to any malformed directive rather than specifically an unmatched ^ENDIF.

An ^ENDIF directive had no matching ^ifdef/^ifndef — balance the preprocessor block.
