[aspectc-user] Problem parsing CORBA template class.

[Toni SOUEID]

Hello Olaf,

Indeed I did not know I have to generated myself the
ac_gen.cc file in STU mode.

Now this particular error has gone.

Instead I am now blocked on another error that is the
following :

----------------
distributeur_impl.cxx:56: no `void 
Distributeur_i::__exec_old_register_client ()' member
function declared 
in class `Distributeur_i'
distributeur_impl.cxx:69: no `void
Distributeur_i::__exec_old_destroy 
()' member function declared in class `Distributeur_i'
distributeur_impl.cxx:90: no `void 
Distributeur_i::__exec_old_inserer_piece (double)'
member function 
declared in class `Distributeur_i'
distributeur_impl.cxx:100: no `void 
Distributeur_i::__exec_old_choisir_boisson (const char
*)' member 
function declared in class `Distributeur_i'
distributeur_impl.cxx:110: no `void 
Distributeur_i::__exec_old_recuperer_boisson ()'
member function 
declared in class `Distributeur_i'
make: *** [distributeur_impl.o] Error 1
----------------

I suppose that the new modified code is unable to find
the functions mentioned above which represent my code
although i can see that they are inline functions
inside my c++ source file.

Does the problem has to do with using the old header
files and not letting ac++ generated new ones ?
