Library build error (HELP ME)

[system]

i'm trying to create a library to have motor control through a sabertooth 2 x 10A motor controller when i put the header file and the cpp file in the arduino/hardware/librairies/motorcontrol and open the arduino program it gives me this error:

MotorControl.cpp:142: error: expected unqualified-id before 'void'

Hey, look at the line 142 You have there

void MotorControl::void STOP()

The second void is your problem.

THANKS what a simple mistake i was looking at it for too long
but im still getting errors now that i modiffied my program

the .pde file is:

#include <MotorControl.h>

int led = 13; // LED connected to digital pin 13

MotorControl motorcontrol(10,11)

void setup() // run once, when the sketch starts
{
int y;

pinMode(led, OUTPUT);
Serial.begin(115200); // set up Serial library at 115200 bps
LEDBurst();
LEDBurst();
LEDBurst();
LEDBurst();
LEDBurst();
}

int x,y;

void loop() // run over and over and over and over and over and over and over again
{
LEDBurst();
MotorControl.STOP();
delay(80);

LEDBurst();
MotorControl.FORWARD();
delay(80);

LEDBurst();
MotorControl.STOP();
delay(80);

LEDBurst();
MotorControl.SPINRIGHT();
delay(100);

LEDBurst();
MotorControl.STOP();
delay(80);

LEDBurst();
MotorControl.SPINLEFT();
delay(100);

LEDBurst();
MotorControl.STOP();
delay(80);

LEDBurst();
MotorControl.BACKWARD();
delay(80);

}

void LEDBurst()
{
for (x=0;x<5;x++)
{
digitalWrite(led, HIGH); // sets the LED on
delay(25); // waits for a second
digitalWrite(led, LOW); // sets the LED off
delay(25); // waits for a second
}
}

but the error when i try to compile this is:

I think that your problem is on the line

MotorControl motorcontrol(10,11)

You are missing a semicolon there. Should be

MotorControl motorcontrol(10,11);

Also, you have to use

motorcontrol.forward();

not your original

MotorControl.forward();

[system]

ok so i fixed what you said so my code is now:

#include <MotorControl.h>

int led = 13; // LED connected to digital pin 13

MotorControl motorcontrol(10,11);

void setup() // run once, when the sketch starts
{
int y;

pinMode(led, OUTPUT);
Serial.begin(115200); // set up Serial library at 115200 bps
LEDBurst();
LEDBurst();
LEDBurst();
LEDBurst();
LEDBurst();
}

int x,y;

void loop() // run over and over and over and over and over and over and over again
{
LEDBurst();
motorcontrol.STOP();
delay(80);

LEDBurst();
motorcontrol.FORWARD();
delay(80);

LEDBurst();
motorcontrol.STOP();
delay(80);

LEDBurst();
motorcontrol.SPINRIGHT();
delay(100);

LEDBurst();
motorcontrol.STOP();
delay(80);

LEDBurst();
motorcontrol.SPINLEFT();
delay(100);

LEDBurst();
motorcontrol.STOP();
delay(80);

LEDBurst();
motorcontrol.BACKWARD();
delay(80);

}

void LEDBurst()
{
for (x=0;x<5;x++)
{
digitalWrite(led, HIGH); // sets the LED on
delay(25); // waits for a second
digitalWrite(led, LOW); // sets the LED off
delay(25); // waits for a second
}
}

my errors or now:

I think you might want to look at the source files in the output directory. These are what the compiler really sees after the arduino environment does it's magic. Likely there is something screwed up with the way one of those files looks.

so this is the file reporting errors. i have not attempted to edit any of this:

Hey there again. So I tried to compile it for you. It looks like your problem is the line

#include "WConstants.h"

in MotorControl.h.
I don't understand why you have it there in the first place, but when I remove it, the sketch compiles.
Also, use

#include "MotorControl.h"

in the sketch file, not #include <...> as you have there. Hope it helps

[system]

It's probably the usual problem with libraries developed for version 0011 and broken by a change in version 0012. A Google of the forums should give you a fix. Or try an upgrade to version 0013.

--Phil.

[system]

I just had the same problem.

after moving
#include "WProgram.h"

from my .h file to .cpp file everything started to work.
However the tutorial here told me to put it in the .h file.
