LOGMSG.h:

//#include "includes.h"
#include "TIMERS.h"

servtime TM;
void LOGMSG(string logmsg)
{
	cout << logmsg.c_str() << TM.years();
}

main.cpp

#include "includes.h"
#include "TIMERS.h"
#include "LOGMSGs.h"
int main()

{
	LOGMSG("test");
}

but i got errors:

Error 9 error C2228: left of '.years' must have class/struct/union
Error 8 error C2079: 'TM' uses undefined class 'servtime'
Error 7 error C2011: 'servtime' : 'class' type redefinition

whats wrong !!!

Put code guards in timers.h fixed the problem for me. Note the preprocessor directives at the top and bottom of the file. This prevents the preprocessor from parsing the file more than once in the same *.cpp file.
