CppParser, CodeCompletion and ClassView Problem

[Robert Gruber]

Hi,

i've got some questions about the classview and the new codecompletion in 
"kdevelop/3.5" branch.

At work I use KDevelop to develop our software. It is written mainly in ANSI-C 
but gets compiled by g++ and therefor each implementation file (*.cc and *.c) 
and header file has a >> extern "C" { .... } << around the declaration and 
the definition of the functions.


1) [ Actually I don't really know if this is a problem of the parser or the 
classview ]
Unfortunatly the functions that are defined inside the extern "C" block do not 
show up in the classview at all but gets shown in the "Functions in file" 
combobox.

What is really strange is this. If I remove the extern "C" part from both the 
header and the implementation file, the functions show up in the classview 
and when I select one KDevelop jumps to the declaration of the function. But 
I still cannot jump to the implementation of the function. I only saw this 
behavior if the implementation of the function is inside a *.cc file. It 
seams to me that if the functions are in a *.c file the classview can jump to 
both the declaration as well as to the implementation.

So my questions are: Is there a problem with extern "C" in the parser? And 
does the parser or the classview ignore *.cc files?


2)
I also have some strange behavior with the codecompletion. 
First of all our project contains several hundreds of files. In some files I 
get codecompletion in most of then not. 

If codecompletion works in a file I only get the localy defined variables and 
the parameters of the function. Not a single function shows up in the 
selection list. (This might be related to the extern "C" problem 
somehow!?!?). But for most of the files codecompletion does not works at all. 
Hitting <Ctrl>+<Space> has no effect. What really confuses me is, that I 
can't find big differences between files with working and files with none 
working codecompletion.



Here are some messages that get written to stdout while loading the project:

Hopefully this helps you in any way. If you need any further information or 
there is anything else I could do just let me know.

Just to make sure, I'm using KDevelop compiled from sources from the 
"kdevelop/3.5" branch. Last updated on 30th of May with my developer svn 
account.


Best Regards, Robert
