Informix Error -4058: Symbol with constructor name is not a function.

Reasons / Common Causes

-4058 fires when a class name is followed by the name of a member variable or constant in a context where that's not allowed — per the official guidance, a class name followed by a non-function member name isn't a valid construct there.

1. A class name followed by a member variable/constant name where a function call is expected, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Review the statement and use the correct syntax for accessing the class's member variable/constant, rather than treating the class name as if invoking its constructor with that name.

Examples

A class name followed by a non-function member

LET x = Order.maxItems
-- -4058: maxItems is a member constant, not something invoked via Order(...)

Corrected

LET x = Order::maxItems

Diagnostic Checks

1. Check the context in which a class name is followed by a member name, and use the correct access syntax for that member's kind.
