Mingw32 gcj & CNI

[Guironnet Fabien]

Hello,

I've build 2 cross-compilers for win32 (gcc 3.4.2 (20040709) et 3.5.0 
(20040822)).
When I try to compile GTK applications with these compilers, all work 
fine, but when I try the code sample from 
http://gcc.gnu.org/onlinedocs/gcj/Invocation.html I've problems...

If I try :
mingw32-g++ test.cc -o test.exe -lgcj

If I try :
mingw32-g++ -c test.cc -I/usr/share/gcc3.5.0-cross/include/
mingw32-gcj -o text.exe test.o

the compilation works fine but the last command gives :

Have I missed something in my commands? or my cross-compilers aren't 
well configured?

Thanks for your help,
