I have been developing a complex application in C++ on XCode 2.1 on 10.4.2
and getting occasional undefined symbol errors in surprising places.  This
has become a problem, so I have managed to distill this down to a very
simple program in a clean project:

I'm doing some Java development on my OS X machines (Pismo/400/320MB,
Quicksilver/733/1.2GB, both running 10.3.9).  XCode ont he Pismo is dog
slow but on the QS is relatively better.
Are there any other alternatives to Java?  Does CodeWarrior do it?  Has

Does anyone have a guess for when Java 5 will be out, based on
previous release schedules?
Thanks,

I'm quite new at cocoa and programming in general, am I got stuck with
trying to get open dialogs to work.  Here's the problem:

I have 1 question. If I create a XCode default C++ Command Line application
and change the default main.cpp (remove the return statement) to:
int main(int argc,char** arg) {
}

Various actions cause chown to fail.  Here's an example from one
such situation.  
I created a new user (with administrative privileges), then in
Netinfo Manager changed the home dir for user to be on a

I've written a plugin (an Xtra, in Macromedia argot) for Director which
allows a Shockwave app to open and play audio CDs. The problem I'm
having is that the original Shockwave app was written in such a way that
it is possible to reinitialize the plugin without first closing any

I just tried to compile an old C++ program usind command line g++, and

the trivial C++ tool template in ProjectBuilder.  Same errors:

My Nib file has a window with a button. In Cocoa, how do I programmatically
disable/enable the button?
