Routine declaration syntax error (Or: Where's wlado?)

[Astronouth7303]

:confused: Here's a stumper:


char Autonomous_1 (char State) // <---Right Here!
{
//...
}


The error is a syntax error. It is the only error in the listing, and it is at that line. I have removed 1 or 2 routines, and still get it.

[Greg Ross]

That looks OK on cursory examination. What comes right before that line? Is it possible you have unmatched braces?

a lot of times, it will give you a syntax error and the real error will be 10 lines up from the little green arrow.

#include "printf_lib.h"


/************************************************** *****************************

The only thing above it is comments and #includes

[Greg Ross]

Have you modified printf_lib.h?

[Astronouth7303]

Have you modified printf_lib.h?
Some. Mostly just a #endif at the end.

[Greg Ross]

I added/************************************************** *****************************

* CALLED FROM: anywhere
* ARGUMENTS:
* Input: char State - What is the state of atuonomous
* RETURNS: char - is it finished?
************************************************** *****************************/

char Autonomous_1 (char State) // <---Right Here!
{
//...
}

right after a #include of our stock printf_lib.h. No error. How about if you post your printf_lib.h?

Commenting out the last few declares don't help.

[Greg Ross]

Well, you might be right. I'm still stumped. You didn't do something weird like #defining char, Autonomous_1 or State, did you? (Or parentheses or underscores, taking a lesson from those obfuscated C samples posted elsewhere?)

[Ryan M.]

I'm stumped too... :)

[Alan Anderson]

Since you have an #ifdef/#endif protecting your printf_lib.h from being included multiple times, I suspect the problem is being caused by the line(s) before that #include. Post a bit more context, and look at the other included files for unmatched parentheses or braces or even missing semicolons.

[Astronouth7303]

After 3 of us working on 4 computers last night to get it to compile, we got it to compile. There were various similar problems throughout the new stuff. I have to ask: Is there a limit on the number af function prototypes in a file?

[Greg Ross]

Is there a limit on the number af function prototypes in a file?
Possible. How many did you have?

Is there some reason why you can't use the stock printf lib if it works? If you can't, try remodifying it one change at a time to see what it is.
