Re: Some general questions

Hi,

other have replied already, but I want to pinpoint some details.

The general answer is yes, since they are LGPL. It depends on other 
details and others are more expert than me.

We are not binary compatibile. That's quite tough... different 
architectures, underlying operating systems, linkers... But we aim to be 
quite reasonably source compatible.

There is no ready pre-baked thing for that. I know some people worked on 
a chain. What I recommend is to set up a clean and plain gnustep system 
and compile there, by syncing the source-code through a CVS/SVN/whatever 
system. That's how I do maintain apps and tools which run on both 
systems, and I do that for several. I prefer to tweak the interface 
anyway. The code can sometimes be really 100% the same.

Many free Unices will do fine, although gnustep should work on Apple I 
advise you to have a native one. Any major Linux should do (Debian, 
Gentoo, SuSE... for the latter Richard Stonehouse provides excellent 
packages) and also FreeBSD/NetBSD/OpenBSD are quite well maintained too.


Another route might be to have gnustep-make to Cocoa.

Good luck with your tool. You plan to make keep it proprietary - 
perfectly fine, but take a look at the rest of the GNUstep stuff. For 
example you might want to look in some of the themes.

If you are lucky and don't use "low level" os stuff you might get a 
working windows version quite easily.
