Re: [Opencxx-users] Including selected source files

[Raphael Y. de C. <rca...@im...>]

Thanks very much for the fast help.

Actually, I hadn't notice the documentation appendix page. Maybe if there was a
link from the official openc++ page it would be easier to find... 

I hadn't say that in the first question but I still have a problem in finding
global variables declarations. By what I've seen, It doesn't seems to be a
simple way of finding them. Maybe I'll have to look at the source code...

thanks,
Raphael
