If I successfully compile a Test.java program with gcj Test.java --main=Test -o Test.bin on 64 bit linux, I then have a 64 bit Linux exectuable. If I do similar on 32 bit Linux, I have a 32 bit Linux exectable. If I am running 64 bit Linux, is there a way to use gcj on this to get a 32 bit Linux bin, what should I do for this, where should I look, and can anyone give me any simple, practical instructions on how to set it up?
