Does that seem right?
I don't want to analyze the righteousness of gcj, but I can confirm
that you are seeing the expected behavior. If you want more than a
single class linked, list them all.
Also I have another program that uses only imported classes
and that gives the same error
Java.Lang.UnsupportedOperationException
whether I use either of the above gcj commands,
but it runs in Windows using the sun Java1.5 SDK
under JCreator LE.
The surprising thing to me is that gcj doesn’t tell
me where error came from, no line numbers, no clue.
What do I do?
As is documented here:
http://gcc.gnu.org/onlinedocs/gcj/libgcj-Runtime-Properties.html#libgcj-Runtime-Properties
You can set the gnu.gcj.runtime.NameFinder.use_addr2line system property
to true and you might get line numbers.
If that does not produce the line numbers, the you are in the
unfortunate situation that your libgcj has had the debugging information
stripped out of it.
The source code to libgcj is available from the same place you got
libgcj, so you can look at it and fix it if you desire.
If you cannot fix it, follow the other options I suggested in the other
e-mail.
However, a consolation is that yet another simpler
program runs under both systems.
public class HelloJav {
public static void main(String[] args) {
System.out.println("HelloJav");
} }
No imports, no dependent classes.
Another thing that bothers me is that the gcc-java forum
seems to be dead.
I am not familiar with that forum. But mail sent to java@xxxxxxxxxxx
will be answered in short order.
Does any one use Java?
I do. So do many others.
I feel way out in left field.
I am sorry to hear that.
