Enable syserr log in (game) source (not Client)

dreammaker · June 21, 2016

I have somebodies (mainline) source and he disabled syserr log (in game source not Client source).( I mean syserr file generated by game in CH's) How can I re-enable it ?

EterBase/Debug.h

Maybe you have:

extern void OpenLogFile(bool bUseLogFile = false);

Change with:

extern void OpenLogFile(bool bUseLogFile = true);

EterBase/Debug.cpp

void OpenLogFile(bool bUseLogFIle)
{
	freopen("syserr.txt", "w", stderr);

	if (bUseLogFIle)
	{
		isLogFile = true;
		CLogFile::Instance().Initialize();
	}
}

Or you have deleted all TraceError(const char* c_szFormat, ...);

Hi VegaS I didnt mean Client syserr.txt I mean game generated syserr file in CH's

Look in log.c in libthecore\src\log.c, look there for _syserr function and see if it's commented.

if you have problems post it here as a file and i'll take a look.

I compared it with a different mainline source it seems same. Maybe something else

I don't known, if they're the same then syserr is disabled from another place like \libthecore\include\stdafx.h or \game\src\stdafx.h, check them.
One thing, is disabled your syslog or syserr?
