Compiling Java with MingW32

[TheUnforgiven]

When i try to compile a basic helloworld class using this command:
gcj --main=Test Test.java -o Test

I get this error message:
c:\mingw\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe: cannot find -liconv
collect2: ld returned 1 exit status

Whats wrong?

You need libiconv: http://www.gnu.org/software/libiconv/

Thank you, I'll try that and report back.

OK I got the sources. when I ran Configure it seemed successful but make gave the following errors:

Try to run it using JRE from Sun!

[TheUnforgiven]

but this is a native compile i am not supposed to have a JRE.
the JRE is installed anyway.
