Description sparcmoz 2007-02-20 03:01:07 UTC 
This issue is for tracking progress with gcc4.3 and ecj.

As mentioned at issue 63390 the java parts will not run correctly unless OOo is
build with the Eclipse compiler. Distributions provide this by various methods
but for porting it is preferable to use a method that does not depend on any
specific distribution. In my case I like to build OOo complete and using gcc and
gcj built from gcc.gnu.org sources. 

To build gcj with the eclipse compiler I used the latest sources at svn trunk
and followed the gcc.gnu.org instructions to get ecj (putting ecj.jar in the top
directory). 

The OOo internal stlport module will not build with gcc4.3 yet so I am using a
copy of the debian provided package with a small patch. (This will be a separate
issue.)

separate issues for those. Also a few new types of warnings ...
