Remove the comma after LOG_ALL

LOG_ALL,

Thanks xandel33, but that hasn't cleared up the problem. I changed my enum to 

1
2
3
4
5
6
7
 
enum eLogEntryType
{
	LOG_GENERAL = 0,
	LOG_WARNING,
	LOG_DEBUG,
	LOG_ALL
};


But theres still the same error appearing on compile

Can you post the entire compile error?

Just as a matter of good programming practice, never use a namespace in a header file. You should remove the

 
 
using namespace std;


from your header file and prefix everything that needs to be with std::.

OK, I've tried to tidy this up to make it a bit clearer. I've implemented the suggestions above, but still no luck. The error is caused by the member definition:

utilities::CLogFile m_Log("global_log",LOG_ALL,1);
//returns - error C2059: syntax error : 'string'

Heres the header with the compiler error:

And heres a reduced class with zero functionality (but still the error)

Is there a problem with my member defn?

You can't initialize m_Log like that. You need to initialize it in the constructor:
1
2
3
4
 
myConsoleApplication ()
    :m_log("global_log",LOG_ALL,1);
....
utilities::CLogFile m_log;


I hope this helps! ^_^

Ahhhh ..... Initialization Lists(?) Never really used or paid any real attention to them in examples! Time to read up on them i think!

Thanks rpgfan and everyone else who offered advice. It's appreciated!

Yep, initialization lists. Just beware of them when you play with virtual inheritance. They come back to bite you. ;)
