cozir library not finding .h file

I have installed the cozir library 1.0.3 for the cozir co2 module in Arduino 1.0.5 on ubuntu. When I try to compile I get the error :-

cozir.cpp:14:19: error: Cozir.h: No such file or directory

then others caused by this, even though the Cozir.h file is installed in the same directory.

What mistake am I making ?

If I comment out //#include “cozir.h” from the code below I get the error

error: ‘COZIR’ does not name a type

#include <SoftwareSerial.h>
#include "cozir.h"

 SoftwareSerial nss(3,2);
  
COZIR czr(nss);

void setup()
{
  Serial.begin(9600);
  Serial.println("Setup");
  delay(1000);
}

void loop()
{
  Serial.println("Loop");
  float t = czr.Celsius();
  float f = czr.Fahrenheit();
  float h = czr.Humidity();
  uint16_t c = czr.CO2();
  
  Serial.print("Celcius = ");Serial.println(t);
  Serial.print("Fahrenheit = ");Serial.println(f);
  Serial.print("Humidity = ");Serial.println(h);
  Serial.print("CO2 = ");Serial.println(c);
  
  delay(3000);
}

check if the include is case sensitive.

cozir.h --> Cozir.h

The include statement in the .cpp file should be identical to the include in your sketch and identical to the actual .h file name.

hope this helps,

I have installed the cozir library 1.0.3 for the cozir co2 module in Arduino 1.0.5 on ubuntu.

Where exactly is the file installed ?
Using
#include "cozir.h"the header file should be in the same directory as you program.
Compare that with #include <SoftwareSerial.h>which indicates that the header file is in the libraries folder.

If I comment out //#include "cozir.h" from the code below I get the error

error: ‘COZIR’ does not name a type

COZIR is undefind for compiler because compiler does not able to find out cozir.h (for definition).

The library is in the arduino/libraries folder.

I changed the include in the sketch to #include <cozir.h> and the declaration in the cpp file from Cozir to cozir

It now works many thanks for all the help.
