Re: wrong reference in a virtual table
Thanks a lot for the answer.
But it doesn't help because the current version egcs (gcc version
egcs-2.90.29 980515 (egcs-1.0.3 release))
doesn't support namespace !!!
I'v got:
sorry, not implemented: namespace
This classes with the same name are defined in different .cc files hence the
compiler has to issue an
^^^^^^^^^^^^^^^^^^^^^
error or generate correct code, doesn't it ?
IMHO this is important for the libraries or codegenerators.
