Arduino-mk - fatal error: arduino.h: No such file or directory

Development Tools IDE 1.x

I am playing around with a motor using the pro mini board, trying to build a library to control the direction and pwm.

I followed some instructions on how to create the header files in the Arduino IDE but as I am using Arduino-mk on a Raspberry Pi to compile and upload the code, I think there's some missing steps and compilation goes wrong and throws me an error:

pi@zero:~/playg/arduino/hbridge $ ls
build-pro328  hbridge.cpp  hbridge.h  Makefile  motorControl.ino  upload
pi@zero:~/playg/arduino/hbridge $ make

...

In file included from hbridge.cpp:1:0:
hbridge.h:3:21: fatal error: arduino.h: No such file or directory
compilation terminated.
make: *** [/usr/share/arduino/Arduino.mk:1234: build-pro328/hbridge.cpp.o] Error 1

pi@zero:~/playg/arduino/hbridge $ more hbridge.h
#ifndef HBRIDGE_H
#define HBRIDGE_H
#include "arduino.h"

class HBridge {
	public:
		HBridge(int IN1, int IN2, int PWM);
		void CW();
		void CCW();
		void changeFrequency(int frequency);
		int _IN1, _IN2, _PWM;
};

#endif //HBRIDGE_H

pi@zero:~/playg/arduino/hbridge $ more hbridge.cpp
#include "hbridge.h"

HBridge::HBridge(int IN1, int IN2, int PWM){
	pinMode(IN1, OUTPUT);
	pinMode(IN2, OUTPUT);
	pinMode(PWM, OUTPUT);
	_IN1 = IN1;
	_IN2 = IN2;
	_PWM = PWM;
}

void HBridge::CW(){
	digitalWrite(_IN1, HIGH);
	digitalWrite(_IN2, LOW);
}

void HBridge::CCW(){
	digitalWrite(_IN1, LOW);
	digitalWrite(_IN2, HIGH);
}
void HBridge::changeFrequency(int frequency){
	analogWrite(_PWM, frequency);
}

pi@zero:~/playg/arduino/hbridge $ more Makefile 
ARDUINO_DIR = /usr/share/arduino
BOARD_TAG = pro328
ARDUINO_PORT = /dev/ttyAMA0
ARDUINO_LIBS =
include /usr/share/arduino/Arduino.mk

I'm Guessing I'm missing the arduino header file or I need to link it within the Makefile or something. Appreciate the help.

The problem is that the file name is Arduino.h, not arduino.h. Windows is file name case insensitive so you will sometimes find libraries with this incorrect filename because the developer was using Windows and the code compiles fine, despite it being wrong.

So you just need to open the file ~/playg/arduino/hbridge/hbridge.h in a text editor and change line 3 from:

#include "arduino.h"

to:

#include "Arduino.h"

Thanks, it now compiles fine!

You're welcome. I'm glad to hear it's working now. Enjoy!
