Hi
I don't even really know what "runtime" means, so take this with a
grain of salt.
The Next-runtime has been coded in Assembler, so it is faster than the
gnu-runtime.
It is not compatible, due to the fact that it has been coded in a period
in which there was not "love" between Apple (Next) and Gnu.
Does Swarm really use a different runtime?
Yes. I used, longitme ago, when the first versions of Unix-like were
born on Macintosh platform (Machten ppc), to compile swarm, a version of
objc modified from gcc (POC, portable objective-C compiler), and after a
couple of weeks of hard work, with the help of the Poc-programmer, I had
a minimal version of Swarm 1.4.1. I remember that the problems were in
some objc-gnu code, that the POC programmer helped me to convert.
I mean, "does Swarm use a different runtime than the gnu objective-C
runtime?" Since we get that from gcc, and gnustep also uses it,
wouldn't that be the right path?
Bill and others have been writing as though Swarm hacks the gnu runtime,
and since I don't understand really what a runtime is, I don't know if I
understand that claim.
I attach to this message 3 patches which I think are needed if you want
to compile Swarm from CVS (or 2002-05-14). These only work if you have
the gcc snapshot 2002-09-09 (or newer, I guess). These are needed
because gcc has better/stronger type checking and protocol checking.
Summary:
ObjectSaver.patch: declare + (void)_crash_: anObject in ObjectSaver.h
Customize.patch: declare/implement "fake" method for createBegin.
Signs.patch: series of changes caused by compiler objecting against
comparison of int and unsigned int.
I have not checked these into Swarm CVS, but will if development by the
gcc team stabilized enough. The Customize.patch has this thing that is
a "fake" method so the compiler does not complain that Customize can't
find the factory method createBegin:
+ createBegin: aZone
{
[self subclassResponsibility: @selector(createBegin:)];
return nil;
}
I have not found any less intrusive way to make the error go away, but
I'm glad to hear if you do. One of the experts in the gcc list who was
making revisions in gcc in response to my difficulty suggested I create
a category for that method, but I don't have enough
documentation/examples to know what that would entail. So I did the
thing I could understand.
