You probably meant 3.4.2 - there is no 4.3.
I'm using 3.4.4 (with code::blocks, too).
C++ Classes within a namespace

Yep, I'm dyslexic. [wink] I just upgraded to 3.4.4 and it still doesn't compile. I checked the build options to make sure there wasn't anything unusual in there and it was all set to the defaults.
Here is the zip that contains the project file too. Won't build under a clean install of code::blocks. [wow] Any ideas?

I'm just creating an ordinary C++ console project and adding your files to it... and it compiles.

Doesn't compile with the Visual C++ 2003 toolkit under code::blocks either, unless I remove the .cpp files from the project.

-Remove #include "lwg.h" from lwg_task.h (there is no reason why this should be here)
-Replace #include "lwg.h" from lwg_kernel with #include "lwg_task.h"
Notes!
- Use include guards (in headers) for example:
#ifndef _FOOBAR_H_
#include "foobar.h"
#endif
- Use forward declarations (when possible)
class Foobar;
- Dont include anything useless

There isn't a reason now. But there might be later. Is there not a way to have an all inclusive includes header for the projet?

If you look at the source download then you would notice I am using them. Also

Each of my header files have guard blocks on them to prevent them from being included more then once

This has nothing to do with it. The only problem is within the namespace. If I take them out of the namespace there isn't any problems.
Your problematic file is lwg_task.cpp.
Just follow the includes and You will see why it dont compile.
lwg_task.cpp:
#include "lwg_task.h"
lwg_task.h:
#ifndef _LWG_TASK_H
#define _LWG_TASK_H
#include "lwg.h"
lwg.h:
#include "lwg_task.h"
lwg_task.h:
#ifndef _LWG_TASK_H <<< already defined so it skips Task class declaration etc.
lwg.h:
#include "lwg_kernel.h"
lwg_kernel.h:
[clip]
private:
lwg::Task t; <<< this one is not yet declared
[/clap]
This has nothing to do with namespaces. :)
