Hello all,

when iam doing configure in openjdk-6-6b18-1.8.1.orig

it stops with following error

checking build identification... Built on Fedora release 8 (Werewolf)
(Wed Nov 17 12:03:35 IST 2010)
checking for a GCJ JDK home directory...
configure: error: "A GCJ JDK home directory could not be found."

do i need to get gcj on to my machine , can't i configure it without
gcj and ecj  i already have jdk1.6.0_18 on my machine.

your comment's will be appreciated.
