Re: [xmlvm-users] Disable constant pool

[Paul P. <bay...@gm...>]

As XMLVM currently is, I avoid much of the unnecessary compilation via the
"rsync -zvrc" command.

I have an ANT script that does everything, but assuming "--out=build/xbin"
(your target will be xbin2 though):

   1. Delete everything in "build" except "xbin2"
   2. Run xmlvm.jar on the Java project into build/xbin
   3. Execute "rsync -zvrc build/xbin/build build/xbin/dist build/xbin2"
   4. Delete build/xbin
   5. Do the C compilation in xbin2, not xbin. Because xbin2 was not
   deleted, it will already have the previously compiled files

Note that you'll occasionally want to delete "build/xbin2" when you feel
that it needs to be cleaned.  That of course will cause entire project C
recompilation.

This works for Obj-C projects using XCode as well.

Thanks,
Paul
