Re: Problem with sigc++

It's nice to see this resolved. Perhaps this question should be added to the
FAQ...

Hi again,

Ok, I was right in my previous mail...
See: http://mail.gnome.org/archives/gnome-kde-list/1999-July/msg00012.html


emit clashes with the QT emit !!!

The solution explained in the archive is correct, simply put the include 
to sigc++ BEFORE the includes for QT :)

Yet Another Problem Solved :)

I also plan to create a documentation for config4gnu to write frontends 
since the documentation is missing. I will send you the document as soon 
as finished.

Best Regards.
