Multiple Definition Error

Guest · Post by **Guest** » Wed Jan 28, 2004 7:41 am

When compiling in Dev-C++ i get a multiple definitions error.
i have made sure the header file has a guard against this, but i still get the error. any ideas?

Could you post exactly what the error looks like, what symbol has multiple definitions?

multiple definition of 'device'
thats all it says.

header:

Code: Select all

#ifndef HEADER_H
#define HEADER_H
IrrlichtDevice *device;
#endif

and then i have a couple of source files that include that file.
shouldn't #ifndef prevent multiple inclusion?

use

Code: Select all

#ifndef HEADER_H
#define HEADER_H
extern IrrlichtDevice *device;
#endif

and then in header.cpp or some other cpp file,

Code: Select all

IrrlichtDevice *device;

That should do the trick
