Yes, and yes. Here's the command output from Xcode:

Ld /Users/zhaytee/Projects/NSBang/Xcode/build/Debug/NSBang normal i386
    cd /Users/zhaytee/Projects/NSBang/Xcode
    /Developer/usr/bin/gcc-4.0 -o

Undefined symbols:
  ".objc_class_name_IRCObject", referenced from:
      .objc_class_name_NSBangIRCInterface in NSBangIRCInterface.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

I would expect gcc/ld to complain loudly about the non-presence of the
"netclasses" framework, if it were unable to find same.


Here's an excerpt from the output of nm:

netclasses(single module):
00008ca4 t +[IRCObject initialize]
00000f28 t +[NSFramework_netclasses frameworkClasses]
00000efe t +[NSFramework_netclasses frameworkEnv]
00000f08 t +[NSFramework_netclasses frameworkPath]
...
00012fe0 S ___objc_class_name_IRCObject
...

So, clearly the IRCObject class is tucked away in there. Why can't ld see it
when I compile my Xcode project, though? I'm rather stumped on this one.

Thanks for your help,
