Created attachment 19955 [details] HelloWorld.java HelloWorld.java i tested
I compiled it with this command line: gcj --classpath=/usr/share/gcc-data/i686-pc-linux-gnu/3.3/java/libgcj-3.3.2.jar -o HelloWorld --main=HelloWorld HelloWorld.java Generated file says: HelloWorld: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.0, dynamically linked (uses shared libs), not stripped
I am pretty sure this can be resolved. The bug reporter should check what CLASSPATH environment variable is defined (it probably contains the blackdown .rt.jar etc) mkennedy@killr:~$ gcj --bootclasspath=/usr/share/gcc-data/i686-pc-linux-gnu/3.3/java/libgcj-3.3.2.jar --classpath="" -o HelloWorld HelloWorld.java --main=HelloWorld mkennedy@killr:~$ ./HelloWorld Starting Finished
