You need to specify to gcj what it should do, obviously there is no
useful default setting.
If you specify `-C' the manpage says:
-C This option is used to tell gcj to generate bytecode (.class files)
rather than object code.
I would expect that you get an error like this without specifying
anything:
$ gcj Foo.java
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../libcygwin.a(libcmain.o)(.text+0x7a):
undefined reference to [EMAIL PROTECTED]'
collect2: ld returned 1 exit status
Anyway, if you want to build an executable, you say s.th. like this:
$ gcj --main=Foo -o Foo Foo.java
and to get bytecode you say:
$ gcj -C Foo.java
