[Asterisk-Dev] Solaris Port (was: asterisk-users: Re: Fedora Core 2 and Kernel 2.6)

Thu May 20 16:40:04 MST 2004

OK, so maybe if someone on the list here can get 
some traction at Sun, maybe one of the things 
that they could whip into shape would be a 
"professional" update of Asterisk code into 
autoconf, and then the dedication to help with 
keeping that methodology up-to-date in CVS.

As I said, the only guy that I know at Sun is 
leaving, so anyone else know someone at Sun that 
might be able to make this happen (excepting, of 
course, Scott McNealy who probably could get it 
done, but probably doesn't work at those tactical 
levels.)

However, let's keep our feet on the ground - I'm 
still just trying to get it to run on OpenBSD 
with PRI cards, so maybe Solaris is reaching too 
far.  ;-)
