Info

A #DEFINE identifier is being used but no parameters were specified, as required. For example: #define min(x,y) ((x
Error Messages A function and all of the INLINE functions it calls must fit into one segment (a hardware code page). For example, on the PIC16 chip a code page is 512 instructions. If a program has only one function and that function is 600 instructions long, you will get this error even though the chip has plenty of ROM left. The function needs to be split into at least two smaller functions. Even after this is done, this error may occur since the new function may be only called once and the linker might automatically INLINE it. This is easily determined by reviewing the call tree. If this error is caused by too many functions being automatically INLINED by the linker, simply add a #SEPARATE before a function to force the function to be SEPARATE. Separate functions can be allocated on any page that has room. The best way to understand the cause of this error is to review the call tree. Parameters must be located in RAM Parameters not permitted An identifier that is not a function or preprocessor macro can not have a ' ( ' after it. Pointers to bits are not permitted Addresses cannot be created to bits. For example, &X is not permitted if X is a SHORT INT. Previous identifier must be a pointer A -> may only be used after a pointer to a structure. It cannot be used on a structure itself or other kind of variable. Printf format type is invalid An unknown character is after the % in a printf. Check the printf reference for valid formats. Printf format (%) invalid A bad format combination was used. For example, %lc. Printf variable count (%) does not match actual count The number of % format indicators in the printf does not match the actual number of variables that follow. Remember in order to print a single %, you must use %%. Recursion not permitted The linker will not allow recursive function calls. A function may not call itself and it may not call any other function that will eventually re-call it. Recursively defined structures not permitted A structure may not contain an instance of itself. Reference arrays are not permitted A reference parameter may not refer to an array. Return not allowed in void function A return statement may not have a value if the function is void. RTOS call only allowed inside task functions Selected part does not have ICD debug capability STDOUT not defined (may be missing #RS 232) An attempt was made to use a I/O function such as printf when no default I/O stream has been established. Add a #USE RS232 to define a I/O stream. Stream must be a constant in the valid range I/O functions like fputc, fgetc require a stream identifier that was defined in a #USE RS232. This identifier must appear exactly as it does when it was defined. Be sure it has not been redefined with a #define. String too long Structure field name required A structure is being used in a place where a field of the structure must appear. Change to the form s.f where s is the structure name and f is a field name. 345
