Hi, i have a few classes in namespaces. They worked earlier, but now after i wrote some more code, they can't find each other. Here is all code: http://code.google.com/p/cgdk/source/browse/#svn/trunk/CGDKFramework The important files for this problem is _stdlibrary.hpp, Vector.hpp & Vector2.hpp Here is all errors i get: 

Error	1	error C2039: 'Vector' : is not a member of 'CGDK::core'	c:\documents and settings\nti\mina dokument\visual studio 2005\projects\cgdk\cgdkframework\vector2.hpp	11

I'm not entirely sure, but it looks like it cannot find the libraries you are using. I get similar errors when I either don't include the right files or it cannot find the files.

_stdlibrary.hpp which all files includes, contains include statements for both Vector.hpp and Vector2.hpp. So they should find each other afaik..

Did you add some #using statements or change some namespaces? This can happen if you have objects in different namespace with same name.

But my guess is you accidentally cut the end brace off of a namespace somewhere. Happens to me once in a while if I hack on lots of files at once and looks exactly like this.
This is my thread. There are many threads like it, but this one is mine.

Consider #includeing _stdlibrary.hpp. Eventually this #includes Log.hpp, which #pragma onces and in turn #includes _stdlibrary.hpp again. This time we pass over Log.hpp as it has a #pragma once directive processed for it. We #include Exception.hpp instead, and similarly to Log.hpp, it #pragma onces and #includes _stdlibrary.hpp again. We skip over Log.hpp and Exception.hpp, and #include MemoryObject.hpp.

This sort of thing continues through MemoryPointer.hpp, Collection.hpp, Vector.hpp, and finally Vector2.hpp. Since when Vector2.hpp #includes _stdlibrary.hpp all the other headers have been #include'd once, compilation moves out of _stdlibrary.hpp, back into Vector2.hpp proper, which it then attempts to compile. Of course, CGDK::core::Vector has not been defined yet.

In effect, the headers at the bottom of _stdlibrary.hpp are being #included in reverse order!

To see that this is indeed the case, change the #include order at the bottom of _stdlibrary.hpp to:

//Exceptions, asserts#include "Log.hpp"#include "Exception.hpp"//For classes#include "MemoryObject.hpp"#include "MemoryPointer.hpp"//Vectors#include "Vector2.hpp"#include "Vector.hpp"//Dynamic memory#include "Collection.hpp"


Your code then compiles cleanly. (Note that this is NOT a long term solution! :])

You need to stop using one header as a "catch-all" that includes every single other header, and put a little more thought into the headers that each header really needs to include.

(As an aside, your SVN repo is missing your MSVC project file.)

Have you made sure you don't have anything else named the same as your namespace?

eg.

namespace Test
{
}

class Test
{
};
