I'm looking for some advice on properly setting up this kind of development environment for Win32
If you check the source readme, it looks like you need to have php 4.0.5 from CVS.
I'd guess you'd have to have the GTK libs set up correctly as well. Setup dint seem very obvious to me so I think I'll give it a little time before I try it out.
You can get 4.0.5 from php4win.de and they have an addon for the GTK stuff. I tried it and it works pretty well. There's a DOS window running behind the GTK stuff, but it works nonetheless. I'll maybe make an installer that installs PHP for app development independent of a web server. Might be a fun diversion.
