Heya,
I've got a bit further with this, by specifying LIBS="-ldispatch -lobjc" and
LDFLAGS="-L/usr/GNUstep/Local/Library/Libraries", configure now succeeds!
Unfortunately, make is not so successful. Linking additions fails, it appears
clang isn't getting any linker flags passed in when it links:
make messages=yes reports that this command is being invoked:
clang -nostdlib -r -shared-libgcc -fexceptions -o ./obj/subproject.o
obj/Additions.obj/GSObjCRuntime.m.o obj/Additions.obj/GCObject.m.o
obj/Additions.obj/GCArray.m.o obj/Additions.obj/GCDictionary.m.o ob
j/Additions.obj/GSLock.m.o obj/Additions.obj/GSMime.m.o
obj/Additions.obj/GSXML.m.o obj/Additions.obj/GSFunctions.m.o
obj/Additions.obj/GSInsensitiveDictionary.m.o
obj/Additions.obj/NSArray+GNUstepBase.m.o obj/
Additions.obj/NSAttributedString+GNUstepBase.m.o
obj/Additions.obj/NSBundle+GNUstepBase.m.o
obj/Additions.obj/NSCalendarDate+GNUstepBase.m.o
obj/Additions.obj/NSData+GNUstepBase.m.o obj/Additions.obj/NSDebug+GN
UstepBase.m.o obj/Additions.obj/NSError+GNUstepBase.m.o
obj/Additions.obj/NSFileHandle+GNUstepBase.m.o
obj/Additions.obj/NSLock+GNUstepBase.m.o
obj/Additions.obj/NSMutableString+GNUstepBase.m.o obj/Additions.ob
j/NSNumber+GNUstepBase.m.o obj/Additions.obj/NSObject+GNUstepBase.m.o
obj/Additions.obj/NSPropertyList+GNUstepBase.m.o
obj/Additions.obj/NSProcessInfo+GNUstepBase.m.o
obj/Additions.obj/NSStream+GNUstepBase.m.o
obj/Additions.obj/NSString+GNUstepBase.m.o
obj/Additions.obj/NSTask+GNUstepBase.m.o
obj/Additions.obj/NSThread+GNUstepBase.m.o
obj/Additions.obj/NSURL+GNUstepBase.m.o obj/Additions.obj/Unicode.m.o ;
This then promptly produces missing symbols for basically everything, because
it's not getting told to link in libobjc, or even the standard C libraries.
Anyone got any ideas how to get this a bit further?
Thanks
