Hi Group

I'm using namespaces in my project, and have the following two classes

namespace A
class foo //Interface

namespace A
namespace B
class foo //Implementation

The compilation runs without problems, but Eclipse shows an error under
problems, that I have conflicting names. Is there somewhere I can tell
Eclipse that it is ok, or shut down this check?

Best Regards
S

It might be a problem with the parser. If you can please post the source
code that causes the problem.

you are defining 'communicationlayer' namespace twice (above and below).
This is not allowed. Do you mean that you want to use the namespace
inside the new defined name space?

One possibility that you may want to consider the following... design
your classes with no name space. Just write normal code when defining
your classes and such. Now, when you implement them, then use namespaces.

namespace rs232
{
TransportLayer *tL = new TransportLayer();
}

main()
{

rs232::tL->init();

{ // -----------------------------
using namespace rs232

tL->yourCodeFunction();

} // -----------------------------
}

and in this way you keep zero namespace corruption, which may be your
intended result after all.

Miguel.

Assuming the missing closing braces in transportLayerInterface.hpp is just a
typo, the idea is ok. Namespaces are allowed to be have their definitions
split up like that and both communicationlayers are the same namespace.

The problem marker is likely a bug with the parser. I don't know what
version of CDT you are using, but in the latest from cvs (soon to be CDT
3.0M7) I don't get a problem marker with this pattern.

Hi Andrew...

Yes, you are right. Splitting namespace definitions does compile/work
alright (any simple example can show this). Thank you for making this
point clear.

3.1M6 must be the version of Eclipse that you are using. Do you know what
version of CDT you are using?
