16-Bit C Compiler User’s Guide #endif without #if In a preprocessor conditional, the #if must be used before using the #endif. #error ‘message’ This error appears in response to a #error directive. #if with no expression A expression that evaluates to a constant arithmetic value was expected. #include expects “FILENAME” or The file name for the #include is missing or incomplete. It must be enclosed by quotes or angle brackets. ‘#’ is not followed by a macro parameter The stringsize operator, ‘#’ must be followed by a macro argument name. ‘#keyword’ expects “FILENAME” or The specified ‘#keyword’ expects a quoted or bracketed filename as an argument. ‘#’ is not followed by a macro parameter The ‘#’ operator should be followed by a macro argument name. ‘##’ cannot appear at either end of a macro expansion The concatenation operator, ‘##’ may not appear at the start or the end of a macro expansion. A a parameter list with an ellipsis can’t match an empty parameter name list declaration The declaration and definition of a function must be consistent. “symbol” after #line is not a positive integer #line is expecting a source line number which must be positive. aggregate value used where a complex was expected Do not use aggregate values where complex values are expected. aggregate value used where a float was expected Do not use aggregate values where floating-point values are expected. aggregate value used where an integer was expected Do not use aggregate values where integer values are expected. alias arg not a string The argument to the alias attribute must be a string that names the target for which the current identifier is an alias. alignment may not be specified for ‘identifier’ The aligned attribute may only be used with a variable. ‘__alignof’ applied to a bit-field The ‘__alignof’ operator may not be applied to a bit-field. alternate interrupt vector is not a constant The interrupt vector number must be an integer constant. alternate interrupt vector number n is not valid A valid interrupt vector number is required.

Diagnostics ambiguous abbreviation argument The specified command-line abbreviation is ambiguous. an argument type that has a default promotion can’t match an empty parameter name list declaration. The declaration and definition of a function must be consistent. args to be formatted is not ... The first-to-check index argument of the format attribute specifies a parameter that is not declared ‘…’. argument ‘identifier’ doesn’t match prototype Function argument types should match the function’s prototype. argument of ‘asm’ is not a constant string The argument of ‘asm’ must be a constant string. argument to ‘-B’ is missing The directory name is missing. argument to ‘-l’ is missing The library name is missing. argument to ‘-specs’ is missing The name of the specs file is missing. argument to ‘-specs=’ is missing The name of the specs file is missing. argument to ‘-x’ is missing The language name is missing. argument to ‘-Xlinker’ is missing The argument to be passed to the linker is missing. arithmetic on pointer to an incomplete type Arithmetic on a pointer to an incomplete type is not allowed. array index in non-array initializer Do not use array indices in non-array initializers. array size missing in ‘identifier’ An array size is missing. array subscript is not an integer Array subscripts must be integers. ‘asm’ operand constraint incompatible with operand size The asm statement is invalid. ‘asm’ operand requires impossible reload The asm statement is invalid. asm template is not a string constant Asm templates must be string constants. assertion without predicate #assert or #unassert must be followed by a predicate, which must be a single identifier. ‘attribute’ attribute applies only to functions The attribute ‘attribute’ may only be applied to functions. © 2008 Microchip Technology Inc.
