(fwd) Re: Recognizing gcj as default StandardVM (JRE System Library)
Hallo!
http://people.redhat.com/~jhealy/eclipse
Seems that the debian gcj is also recent enough. Lets wait for the
patches... I'm curently downloading the src.rpms to have a look inside...
(none for gcj yet...)
If eclipse can run on gcj, we can probably have all the other contrib
java packages in main as well. Or is interpreter mode not enough?
What will then be the policy for 'native compiled java binaries'? Name
them differently? Just compile everything to native (if that
works...)?
I must say that this sounds very good, but as far as I can tell about
me, its going back to reading lots of manuals... when will learnig
ever stop...

No worries. Although gcj normally takes a "radically traditional"
approach to the language by just treating it as another thing to compile
to native code (like C, C++, Fortran, Mercury, etc.) it also comes with
gij, an interpreter for byte code. Although using gij doesn't give you
much of the advantages of normal natively compiled applications and
shared libraries produced with gcj. You can still play with it to see
what can be done in a way that might be more

With the just released RPMs I have been able to run the natively
compiled eclipse (eclipse plus plugins all compiled to native code). And
I have been able to run a traditional eclipse release (as downloaded
from eclipse.org) with just the gij interpreter that comes with those
RPMs. You can run such a traditional eclipse with the '-vm gij-ssa'
option. (Using the interpreter is clearly slower then using native code,
but I was surprized by how fast it still was.)
The /usr/bin/java script wrapper around gij is mostly for convenienve
since eclipse expects a java byte code interpreter (that is called
'java') to execute user created code. And it expects that java binary to
have the sun.boot.class.path system property to be set.

I don't have that much experience with Eclipse but it seemed that most
things worked out of the box.
Cheers,
