They (we?) should. Although I don't think any of the main developers
use MacOSX so we would rely on patches and bug reports from others.
I don't think your patch will work though, since you need the garbage
collecting classes for gdl2. We're working on a compatibility library
that you could compile on MacOSX to get this to work.
Well, if we could avoid using that garbage collector... You wrote that
gdl2 should be usable without GC, so why hardcode superclass
I admit my patch cannot be used as-is; in fact it was just a
quick-and-dirty one to allow me compile gdl2 on MacOS X, and launch
Anyway, you should at least have a careful look at it: it corrects at
least some bugs in your code (syntax), and points out some problems
like inter-dependency between the two libs (EOControl and EOAccess).
- Does it even compile on a GNUStep system?? I had to correct some
code, independant of platform.
Well, understand that it's not even a released version yet, it's just
No problem. I realized that yesterday when looking more carefully at
the code. I also realized that your goal is WebObjects 4.5.1
compatibility, that's great!
- gdl2 depends on GNUStep-specific classes, like GCArray, etc. Can
this dependency be removed? There are also references to methods not
implemented in MacOS X, like subclassResponsibility:, but in these
cases we could implement categories on MacOS X for GNUStep
- gdl2 is not consistent regarding retain/release and garbage
collecting; sometimes macros are used for retain/release, sometimes
method calls are used. How should it be done?
macros should be used, since it's possible to compile GNUstep with
automatic garbage collection, so that retain/releases aren't even
I understand that. The fact is that currently gdl2 implementation is
not consistent at all. Needs a spring cleanup.
Finally, I suppose there are a lot of Cocoa developers willing to use
EOF... erh gdl2 ;-)
I suppose GNUStep people will find help among them. There are also a
lot of former OpenStep/WO4 developers that could help, now that there
is a concrete opensource EOF for Cocoa. So please, subscribe to that
list, checkout gdl2 and give GNUStep developers needed help. I'll try
