16-Bit C Compiler User’s Guide duplicate case value Case values must be unique. duplicate label ‘identifier’ Labels must be unique within their scope. duplicate macro parameter ‘symbol’ ‘symbol’ has been used more than once in the parameter list. duplicate member ‘identifier’ Structures may not have duplicate members. duplicate (or overlapping) case value Case ranges must not have a duplicate or overlapping value. The error message ‘this is the first entry overlapping that value’ will provide the location of the first occurrence of the duplicate or overlapping value. Case ranges are an extension of the ANSI standard for the compiler. E elements of array ‘identifier’ have incomplete type Array elements should have complete types. empty character constant Empty character constants are not legal. empty file name in ‘#keyword’ The filename specified as an argument of the specified #keyword is empty. empty index range in initializer Do not use empty index ranges in initializers empty scalar initializer Scalar initializers must not be empty. enumerator value for ‘identifier’ not integer constant Enumerator values must be integer constants. error closing ‘file’ The system cannot close the specified ‘file’. Possible causes are not enough disk space to write to the file or the file is too big. error writing to ‘file’ The system cannot write to the specified ‘file’. Possible causes are not enough disk space to write to the file or the file is too big. excess elements in char array initializer There are more elements in the list than the initializer value states. excess elements in struct initializer Do not use excess elements in structure initializers. expression statement has incomplete type The type of the expression is incomplete. extra brace group at end of initializer Do not place extra brace groups at the end of initializers. extraneous argument to ‘option’ option There are too many arguments to the specified command-line option.

F Diagnostics ‘identifier’ fails to be a typedef or built in type A data type must be a typedef or built-in type. field ‘identifier’ declared as a function Fields may not be declared as functions. field ‘identifier’ has incomplete type Fields must have complete types. first argument to __builtin_choose_expr not a constant The first argument must be a constant expression that can be determined at compile time. flexible array member in otherwise empty struct A flexible array member must be the last element of a structure with more than one named member. flexible array member in union A flexible array member cannot be used in a union. flexible array member not at end of struct A flexible array member must be the last element of a structure. ‘for’ loop initial declaration used outside C99 mode A ‘for’ loop initial declaration is not valid outside C99 mode. format string arg follows the args to be formatted The arguments to the format attribute are inconsistent. The format string argument index must be less than the index of the first argument to check. format string arg not a string type The format string index argument of the format attribute specifies a parameter which is not a string type. format string has invalid operand number The operand number argument of the format attribute must be a compile-time constant. function definition declared ‘register’ Function definitions may not be declared ‘register’. function definition declared ‘typedef’ Function definitions may not be declared ‘typedef’. function does not return string type The format_arg attribute may only be used with a function which return value is a string type. function ‘identifier’ is initialized like a variable It is not legal to initialize a function like a variable. function return type cannot be function The return type of a function cannot be a function. © 2008 Microchip Technology Inc.
