Arduino Rocket Ejection at Certain Altitude

LividKiwi:
Sure I will post pictures!
This is the code im using. Im getting an error at the highlighted place, And I cant solve it no matter what i do.
#include <Wire.h>
#include <BMP085.h>

Adafruit_BMP085 bmp;

As PaulS noted this is probably due to the correct header file not being loaded.

Replace:

#include <BMP085.h>

With:

#include <Adafruit_BMP085.h>
