I finally found time to try ac++ with VC8.
Your advice helped me a lot as I had the Trace example producing
weaved source file.
I didn't try to compile this file as it wasn't relying on very complex
Instead, I directly tried to weave a very simple aspect on one of my
project cpp file.
That's where troubles got in (4 of them).
I don't intend to ask you with this mail to solve them as VC8 is not
clearly stated as been supported, but rather help you (a little) for
your future port of visual studio 7 Plug-in toward the VC8 version.
All these troubles occurred at parsing step while using the -v9 option
Here they are :
1) ac++ don't seem to support that kind of include preprocessor
command containing windows style backslash path separators :
But maybe it is rather due to Visual Studio supporting an out of
C++ specification feature ?
2) I got stuck on a strange class declaration :
Here is a simplified extract of what is causing this trouble :
template <bool _SECURE_VALIDATION>
class _Iterator : public _Const_iterator<_SECURE_VALIDATION>
typedef typename _If<_SECURE_VALIDATION,
ac++ don't like the first friend declaration.
Note that, as I don't know what can cause this trouble, maybe I
simplified too much this extract.
3) The following extract of file crtwrn.h is not parsable for
ac++ because of the second backslash :
#define _CRTWRN_MESSAGE__NO_ITERATOR_DEBUGGING Iterator debugging not \
supported in retail builds.\n \
4) The "using namespace" formulation doesn't seem to be
supported by ac++, at least fot the following example:
#include <aFile.h> // namespaces are declared within aFile.h
using namespace namespaceOne;
class A : public B
// namespaceTwo is defined within namespaceOne
An error is reported on "myVariable" declaration.
Hope it will help.

it's definitely not a "piece of cake" to use ac++ directly on VC++ code,
but it's also not a nightmare. I don't exactly know all changes between
VC7 and VC8. But I know that at least new keywords were introduced. If
you have access to a VS2003, then install the AspectC++ Add-In and look
how it solves these problems (there is a configuration file with
#defines and some required declarations in an extra header file that is
automatically included, the Add-In log file contains the corresponding
When the next ac++ release is out (in the near future), then a new
AspectC++ Add-In should be available (for VC7 and for VC8) too.
