I recently started coding in C++ with Visual Studio 2010.
Now I am looking for an option to warn if a function has been declared, but not defined. That option would be found in the compiler options, wouldn’t it? After a quick search on Google I found this: http://msdn.microsoft.com/en-us/library/c553zwz0.aspx which is exactly what I needed… except (this may be due to me using the German version of Visual Studio) I can’t find the compile tab on the Project properties.
Just to make sure: We have a solution (root node in the Solution explorer) and its child nodes are the projects (am I right?) after right clicking what translates to “properties” I end up in a window called “-Properties”. But that window has no tab layout. It looks like this:

How can I fix this?
In that window expand ‘Konfigurationseigenschaften‘, expand the child ‘C/C++‘ and select ‘Allgemein‘. Now you can set the warning level (Warnstufe) to EnableAllWanings (/Wall).
Though I don’t think the warning you are looking for exists, at least I couldn’t produce it.
