[Qt-interest] Dependency between CppEditor and CppToolsPlugin / Need Advise in adding functionality

[variadic.template]

Hi,

something i'm really missing in qtcreator (and all other cpp-editors i'm  
using) is
a "create method-body for method-declaration"-function. For example:

file class.h:

class foo
{
public:
	void x();	// now trigger "createMethodBody"
};

-> class.cpp

creates automagically the empty method body and moves the cursor into it

void foo::x()
{

}

As i didn't see a request for this, i started to try it by myself. I  
created
a "createMethodBody"-method in CppEditor, as it seems like the right place  
for
this to me.
There I need to find the corresponding cpp-file of the current headerfile.
As this is already done in the "correspondingHeaderOrSource"-method in
CppToolsPlugin, i tried to call it by
CppTools::Internal::CppToolsPlugin::instance()->correspondingHeaderOrSource(file()->fileName());

Now, when starting my own-build qtcreator, I get an error like
"The Plugin can not be loaded because of unsatisfied dependencies:  
CppEditor
[...]
The Library .../libCppEditor.so can not be loaded, undefined symbol _
ZN8CppTools8Internal14CppToolsPlugin10m_instanceE"

There's no need of explaining as I understand and see the problem, but I  
have
no idea how to resolve it in a way that don't break the design of  
qtcreator.

I'm open for suggestions.

Regards,
Hendrik
