#ifndef __Main_Log
#define __Main_Log
namespace OUT {
	bool initiated;	//true if its ready, false otherwise
	void init();	//must be called before logging is to occur
	void log(std::string);	//basic out
	void warn(std::string);	//more serious out
	void crit(std::string);	//something that would cause the program to fail if it's not fixed...out
	bool checkFileExistance(std::string);	//true if it does, false otherwise
}
#endif


I plan to call OUT::init() from another file. I have my calling methods working, but when I attempt to compile this, I get:
Main_Log.cpp: In function ‘void OUT::init()’:
Main_Log.cpp:11:34: error: ‘checkFileExistance’ was not declared in this scope

I added that...now I am getting:
Main_Log.cpp:8:7: error: redefinition of ‘bool OUT::initiated’
Main_Log.hpp:4:7: error: ‘bool OUT::initiated’ previously declared here


if I remove the bool on line 7 of Main_Log.cpp, then I get:
Main_Log.cpp:8:2: error: ‘initiated’ does not name a type

Thanks so much, that fixes so many problems. The extern did it for me.
