C4005: 'AF_IPX' : macro redefinition

SPlatten

@jsulm , sorry, I'm compiling on Windows 10 using Qt Creator and Qt 5.8, the compile is Microsoft I have a couple of versions installed, MSVC 2013 and 2017, I think its using 2013.

Its a large project which I'm converting from Qt 4.8 to Qt 5.8. Hope that helps?

@SPlatten Where in your project does the error come from? I mean from which source/header file.

SPlatten

It seems to come from several files all of which are specific to this project. The problem seems to be moving and changing as I fix one thing another results...see edit which I'm about to do...

jsulm

@SPlatten Could it be related to missing include guards: https://stackoverflow.com/questions/1372480/c-redefinition-header-files-winsock2-h ?

SPlatten

@jsulm I do have guards in the headers, I always start off with:

#ifndef WIN_H // or whatever I call it
    #define WIN_H

//Content of header



#endif

SPlatten

So after my last edit, the problem has changed now I get:

C2146: syntax error: missing ';' before identifier 'IWbemClassObject'

jsulm

@SPlatten Without seeing the code...

SPlatten

@jsulm , sorry its difficult because there is a lot of it.

I wonder what's Qt related here but you're missing a semicolon at the end of a class (mostly the class from the last include before IWbemClassObject)

SPlatten

The whole project is Qt related, granted particular error might not be, I'm just trying to get some assistance. The header that IWbemClassObject is defined in is a Microsoft header, and its path is:

    C:\Program Files (x86)\Windows Kits\8.1\Include\um\WbemCli.h

I've looked at the header and it is a typical error message that has nothing to do with the issue. The line line has the error on it is:

    typedef interface IWbemClassObject IWbemClassObject;

The solution is as always - either give a compilable example or reduce your code until the error goes away.
