iOS Strange Xcode Error

[Programmer]

Does anyone know what this means?
Command

Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/g++-4.2 failed with exit code 1

Look at the Build Results and see what it says. It should give more info.

i'v tried that

Of course i've tried that, its the most obvious thing to do when you get an error, but i get this:

ld: duplicate symbol _right1Appaered in /Users/harryslotwiner1/Documents/ProbeDestroyer2/build/ProbeDestroyer2.build/Debug-iphonesimulator/ProbeDestroyer2.build/Objects-normal/i386/Game.o

and the first error "duplicate symbol _right1Appaered" doesn't make any sense; right1Appaered is a bool that I have set up, but I've checked multiple times and i have not declared it more than one time.

 

[kainjow]

How is it declared, and where? Post some code.

 

[Programmer]

code

i declared it in the .h as a bool like so:

BOOL right1Appaered;

it had been working up until now.
