Hello,

i tried to compile a small Programm with gcj - no success :-(   (using eclipse it works!!):

gcj --classpath=mail.jar:activation.jar -v --main=lantronix.mail.MailSender MailSender.java -o MailSender

Result:

Using built-in specs.
Reading specs from /usr/lib/gcc/i586-suse-linux/4.2.1/libgcj.spec
rename spec startfile to startfileorig
rename spec lib to liborig
