Help !!!

[sonnguyen]

Hi,

When I compile today, I get this problem

How can I solve it ? I am using MPLAB v8.00

[zkaratekid]

hey our programmer said that you need to reinstall the upgrade for mplab 8 and make sure you have compiler v. 3

[tdlrali]

gotta fix your project's search paths.
find the project settings in the project menu, and change the paths.
include -> mcc18/h
library -> mcc18/lib
linker -> mcc18/lkr

Can you say more detail ?

I have the v.3 compiler

[tdlrali]

Open MPLab, open the project, go to Project -> Build Options -> Project
Then on the General tab (or something like Paths in v8), set the links like this:
Linker -> mcc18/lkr
Library -> mcc18/lib
Include -> mcc18/h

where mcc18 is the path to your c18 installation

[sonnguyen]

It seems that there is no such tab like you said

[tdlrali]

Well, look around and use common sense, there is one with paths, i know that for sure.

[sonnguyen]

I have done like you said. Now there is another problem

C:\ifi_frc_simple_30\autonomous.c:242:Error: syntax error
Halting build on first failure as requested.

[tdlrali]

Well, check line 242 in the autonomous.c file, there's a syntax error on that line.

[sonnguyen]

void Autonomous_Spin(void)

This is the line. Is there any error ?

[Chaos in a Can]

Check the lines above that for something like a missing brace or semicolon.

Since the C18 compiler gives ever-so-helpful error messages, I can't say for sure, but I'm guessing the compiler was expecting a semicolon at the end of a statement or a closing curly-brace, but instead it found "void Autonomous_Spin(void)".

The syntax error occurred on line 242, but the problem that caused it isn't necessarily on that line. The actual problem is often on the line above the one the compiler says it is.

[tdlrali]

Without the surrounding code, it's hard to tell. Based on that file name, I'm assuming you're using Kevin's v3 code, correct? Did you modify that file?

[sonnguyen]

yeah i did modify the file.

I don't have any code surronding that one

It said it's version is v.0.1

[tdlrali]

Well, without the whole file, it's hard to tell what's wrong, but do you have semicolons and closing brackets everywhere? (Those would result in something more like "expected xx instead of yy" errors, though...)

[Chaos in a Can]

Check the last few lines that have code on them that are before where you get the error.

Better yet, show those lines.

I'm pretty sure C18 doesn't give "expected ..." errors for missing/extra semicolons and braces.
It just says "syntax error".

The only time it seems to give and "expected" error is when you use . instead of -> or the other way around.

[tdlrali]

yeah, you're right, c18 doesn't give those errors, even though it should.

[sonnguyen]

void Teleop(void)
{
// enable this to use IFI's default robot code
// Default_Routine(); // located in ifi_code.c
pwm01 = 255 - Limit_Mix(2000 + p1_y + p1_x - 127);
pwm02 = Limit_Mix(2000 + p1_y - p1_x + 127);
pwm10=pwm11=p2_x;
// update the state of the LEDs on the operator interface
Update_OI_LEDs(); // located in ifi_code.c
}


Here is the part before the error. Can someone help me ?

[Gamer930]

void Teleop(void) is in teleop.c
void Autonomous_Spin(void) where you said the error is located in autonomous.c

your error is going to be in your void Autonomous(void) function. Maybe forgot to close a Bracket or semicolons

[sonnguyen]

Can someone check for me ?

I know this may be a pain, but try commenting out blocks of your code at a time. Comment out a huge block that fixes the problem, then make the block smaller and smaller until you find the line that causes the problem.

[psy_wombats]

Just ran it through a formatting routine in Eclipse. It looks like this line is not closed:

else if ( (!rc_dig_in16) || (!rc_dig_in15) ) // for position 15 or 16
{

Try adding the extra brace back wherever it should be, probably at the end. Either way, a brace is missing.

Eclipse is... useful? On our school computers, it's just plain slow.

[sonnguyen]

The problem is actually, I have tried to compile on another laptop with the same codes and it worked.

What's the problem here ?

[psy_wombats]

Have you tried adding the extra brace right before the function? That code definitely will not compile as is. The syntax error just means the function before it never closed, so it isn't anything compiler specific at the moment.

Or are you getting a different error? If so, what is it?

[sonnguyen]

I mean that I use the same codes on the other laptop and it worked. Thus, It means there shouldn't be anything wrong with the codes

Why doesn't it work on my computer ?

[psy_wombats]

I'll assume you're talking about the syntax error. If not, say so.

The code on the other computer must not be identical, as it does not respond to the syntax error which is apparent. I am quite sure it will dissapear (and therefore compile) if you add the other brace. Try that, and see if the problem goes away. If you have already fixed the brace issue, is the syntax error still there?

[sonnguyen]

where should i put the brace ?

[psy_wombats]

The brace should close this line:

else if ( (!rc_dig_in16) || (!rc_dig_in15) ) // for position 15 or 16
{

I think this ends at the end of the function? If I understand what your code does, put it before this, assuming its where that if ends:

/*Bob's Code ends*/
}

[sonnguyen]

there is another problem after I solved that problem

It says

[psy_wombats]

Okay... Well, did you actually define those? If so, where? Did you include that file's header? You may want to just attach a zip of your entire code. And what are those two values? Are they supposed to be motor macros or actual variables? Where are they referred to?

[paulcd2000]

Can someone check for me ?

void Autonomous(void)
{
...
}

Ok, just a few requests
First, when you want others to read your code, indentation helps. Heck, it even helps if you don't want others to read it. Helps catch closing bracket errors.
Second, when your putting code in, wrap it in code tags
[ CODE][ /CODE]
just remove the spaces inside the braces, and put your code in between. much easier to read
