digitalmars.D.ide - VisualD: C++ to D stops with meaningless error message

I am trying to convert the oscpkt.hh file from this c++ library:
http://gruntthepeon.free.fr/oscpkt/

The wizzard simply stops with this error message:

oscpkt.hh
E:\Code\Lib_CPP\oscpkt-1.2\oscpkt.hh(251): not parsed until the 
end of the file
----------------
1 of 1 files failed to parse, aborting

What are the reason for such an error? What can be done about it?

Cheers, ParticlePeter

I tried the header file and noticed that all previous error messages are 
lost when the parser completely bails out with the error given above. 
I'll try to fix this.

The bad trouble in this header comes from two issues:

- the parser doesn't understand operator overloads, so you'd better 
comment these. There is often no good replacement anyway.

- the parser stumbles over namespaces in type names, e.g. std::vector. 
you might get better results by replacing these with a single identifier 
or just remove the namespace "std::".

In the udp.hh header, there are a lot of "sizeof type" without 
parenthesis. I wasn't aware that these are optional when I wrote the 
parser, so they are mandatory ATM.

Thanks for your reply, I just tried "oscpkt.hh" as starting point.
I couldn't make heads or tails out of the error message, so the 
problem her would be line 247: operator bool() const { return 
isOk(); }
instead of 251?
How about adding the line itself to such an parse error message?

Conversion succeeded, had some more errors but could fix them, 
thanks.

I fixed the suppressed error messages, it prefers a flood of error 
messages instead. The issues above should also be parsed correctly 
(though you'll propably need to replace "std.vector!(char)" with 
something else anyway). See
