no gcj-jdk + no ecj + building openjdk

[ramakanth varala]

Thanks Dr Andrew,

for your reply.

My target is to get openjdk build for target board (ARM) .

In the process i thought i would build openjdk first to my host
machine i.e of fedora 8.

Iam confused of lot of things here

1) what is icedtea ?

2) How is icedtea related to openjdk?

3) can i build this for the arm board ?

4) can you point me to proper documentation where i can get a clear
picture of cross-compilation to arm?

In short iam just  running out of the options to solve my problem.

your suggestion would be highly appreaciated in this regard.
