qtjava (kdebindings-3.5.4-1mdv2007.0.src.rpm)

Hello,

I have the following problem with qtjava: on my suse 10.0
(and 10.1), using
the suse packages, I can get my own programs to compile fine
with gcj and
then run. However, on mandriva 2007.0, using the source rpm
for kdebindings,
then building them, then installing them to have qtjava.jar,
it just fails
to link (if I try to compile and link) or compiles without
errors but fails
to run (both with gcj and javac/java).

The code used to test is the one on
http://www.valdyas.org/fading/index.cgi/hacking/gcj.html


Logs are below:
Compiles with gcj but won't run:
[endlesslocalhost ~]$ export
CLASSPATH=/usr/lib64/java/qtjava.jar
[endlesslocalhost ~]$ gcj -C -classpath $
Hello.java

Maybe you need to explicitly add the current directory or
"." to the classpath
