It isn't visible straight from wxCode because I'm using wxCode's subversion repository instead of the CVS repository. This allowed me to point to it as an external source within our own internal project's svn repo. I also haven't packaged up a release, as I have no documentation or anything to help people build a project. About Avahi, if that's what is commonly shipping on Linux systems, then that would probably be the better route to take on those platforms. As currently implemented, wxDNSSD relies on Apple's implementation. I imagine Avahi wouldn't be particularly difficult to implement into my existing framework. I suspect the structure will likely be very similar (if not identical), but a lot of the code I've written probably won't apply. I have a suspicion it would wind up being a parallel implementation, like much of wxWidgets' cross- platform support. It may not be a bad idea to see if my implementation works with Apple's Bonjour on Linux. If it does, you could still do an Avahi implementation, but this would make it much easier to ensure that software written against wxDNSSD will work the same regardless of the backend. (just an idea) Anyway, I committed a change to servicediscoverytaskbase.h a few minutes ago, so there should be a little more information there on what you need to know to get going. It's getting late, so I'm headed home for the evening. We should probably continue this discussion on the wxCode mailing list. https://lists.sourceforge.net/lists/listinfo/wxcode-users I figured I would mention this before starting to CC the list (in case you have privacy concerns about anything you've already mentioned). ------------------------------- Hank Schultz Cedrus Corporation http://www.cedrus.com/ On Dec 18, 2006, at 5:54 PM, Ishan Arora wrote: > William, > Why is this project not accessible straight from wxCode?

I see. That makes more sense--that it would be source-code compatible, similar to WINE. That would relieve the effort of implementation quite a bit. While it may be a while before I get around to writing serious documentation, I can at least go ahead and put some effort into squeezing this into the existing socket sample. That should help get you up and running. ------------------------------- Hank Schultz Cedrus Corporation http://www.cedrus.com/ On Dec 18, 2006, at 7:01 PM, Ishan Arora wrote: > William, > What I insisted in last post was "Avahi also implements binary > compatibility libraries that emulate Bonjour and Howl".

The project is visible on the main page, but the code itself is not. It's available from the subversion repository, but the provided link points to the CVS repo, which does not contain any of the code. With respect to bakefile... I looked at it yesterday, but I stopped when I realized I was still going to have to learn autoconf. I didn't realize at the time that wxCode provides templates to make this easier. I'll see what I can do. ------------------------------- Hank Schultz Cedrus Corporation http://www.cedrus.com/ On Dec 20, 2006, at 4:12 AM, Francesco Montorsi wrote: > Hi William, > > William H.

William Let me work on bakefile and autoconf. Infact I had already started working on bakefile when i was trying to compile wxDNSSD with Visual Studio. On 12/21/06, William H.

William, I cant access wxCode/build and wxCode/template from wxCode CVS as I don't have a Maintainer's Account.
