[Pyobjc-dev] GNUstep PyObjC compatibility

[Alex P. <ap...@st...>]

Ronald et al,

I lurk on the cocoa-dev mailing list, and recently saw a posting about 
PyObjC. Someone in #macpython on FreeNode told me you'd done the bulk 
(all?) of the work to make PyObjC work with GNUstep once upon a time. 
I'm the GNUstep website maintainer (one of a couple of others), and am 
putting together a page with a list of language bindings to demonstrate 
how many languages you can use with GNUstep. I'd love to help you 
resuscitate the GNUstep support in PyObjC and keep it actively working.

I downloaded the CVS sources to PyObjC a day ago and attempted to get it 
to build, to no avail. Someone told me to look in 
Scripts/gen_all_protocols.py and it looks like there are some hardcoded 
paths in there. GNUstep system header files live in a slightly different 
place than they do on OS X. Foundation and AppKit headers are found in 
$GNUSTEP_SYSTEM_ROOT/Library/Headers/Foundation and 
$GNUSTEP_SYSTEM_ROOT/Library/Headers/AppKit, respectively. There are 
also some InterfaceBuilder (our IB-esque app is called GORM) in 
$GNUSTEP_SYSTEM_ROOT/Library/Headers/InterfaceBuilder. GNUstep also has 
a 100% API compatible AddressBook implementation, but it is not part of 
GNUstep proper, and as such may or may not be on any given machine. If 
it is, the headers would be in 
$GNUSTEP_LOCAL_ROOT/Library/Headers/AddressBook .

For those of you who might be wondering, GNUstep lives in various 
places. I have it installed in / so my System folder is simply /System, 
local is /. Most distributions which package GNUstep put it in 
/usr/GNUstep or /usr/lib/GNUstep, which is why we must use system 
variables such as $GNUSTEP_SYSTEM_ROOT et al.

Cheers for now,
