Wrestling with gcj 4.0 mingw win32

Tue Apr 5 11:43:00 GMT 2005

Hi,
I have been trying to get my programm to run for three days now, 
everything I did was reading documentations and trying to find my error 
But I couldn't.
I used GCJ 3.4 before and it worked fine, now I installed the GCJ 4.0
http://www.thisiscool.com/gcc_mingw.htm I thought I could just change my 
path and run the builds I ran before to see if everything worked.
My buildfile looks like this:
del /f ARClibWriter.jar
gcj -g -c -o entagged-audioformats-0.09.o entagged-audioformats-0.09.jar
gcj -g -c --classpath=entagged-audioformats-0.09.jar -o jd3lib.o jd3lib.jar
cd bin
jar cmfv ..\manifestaddition ..\ARClibWriter.jar *
cd..
gcj -s --classpath=jd3lib.jar --main=arclibWriter.GUI.Starter -o 
ARClibWriter.exe ARClibWriter.jar entagged-audioformats-0.09.o jd3lib.o
The output of the last gcj call is:
c:/gcc/thisiscool-gcc/gcc-4.0/bin/../lib/gcc/i686-pc-mingw32/4.0.0/../../../../i
686-pc-mingw32/lib/libgcj.a(natLogger.o):natLogger.cc:(.text$_ZN4java4util7loggi
ng6Logger7getNameEv[__ZN4java4util7logging6Logger7getNameEv]+0x0): 
multiple defi
nition of `java::util::logging::Logger::getName()'
c:/gcc/thisiscool-gcc/gcc-4.0/bin/../lib/gcc/i686-pc-mingw32/4.0.0/../../../../i

c:\gcc\thisiscool-gcc\gcc-4.0\bin\..\lib\gcc\i686-pc-mingw324円.0.0\..\..\..\..\i
686-pc-mingw32\bin\ld.exe: cannot find -lgdi32
I'm pretty much lost, I don't have much experience in using GCC/GCJ
I don't understand this output. First what are these problems with the 
"java::util::logging:Logger" I thought logging is iplemented 100% 
according to the statuspage.
But what confuses me as gcj newbie even more is that last line "cannot 
find -lgdi32" what is does that mean ? What is missing ?
I was able to compile and run the programm with the gcc3.4 without 
errors. I got a nullpointer exception but I guess that results from a 
programming bug. But the GUI showed and all method calls worked.
Any help would be greatly appreciated because I'm pretty new to this but 
see the potential of the GCJ and would be able to really use it.
Regards,
 Andreas
