[aspectc-user] error: Bad argument(s) for the `cpp_move' manipulator

[Olaf Spinczyk]

Hi Dmitry,

the problem is that ac++ can't weave in macro-generated code, yet. As 
you can see in the output, the call to 'print' is matched, but then the 
code manipulation fails.

This problem is already on our TODO list and you can also find it on the 
roadmap for version 1.0 at aspectc.org.

As a workaround you can only exclude 'call("% print(const char*)") && 
within ("% main(...)")' from your pointcut :-(.

Best regards,

Olaf
