[aspectc-user] Can't use string objects in *.ah files

[Goh, Betty]

Dear all,

I'm trying to build a small sample which uses string objects.

I've included the string header file in the Action.ah file and declared a
string variable like so:
std::string abc = "abcd";

When I try to compile, I get a bunch of errors involving the g++
./ac++ -v9 -Iexamples/Sample -p examples/Sample -d examples/Sample-out
* Running AspectC++ 0.7pre1
* Simple Dependency Check
  - new or modified: examples/Sample/Action.ah
* Handling Translation Unit `main.cc'.
  - Path "examples/Sample/main.cc"

What could the problem be? Can we use string objects in *.ah files? And
also, do we have to use extension cc for our main? Because when I named my
main as main.cpp, nothing is done on the main file.

Thanks.

regards,
Betty
