To import a new release:
- Check out a classpath snapshot
- Check out a classpath snapshot or take a release tar.gz file.
I use 'cvs export' for this. Make a tag to ensure future hackers
know exactly what revision was checked out; tags are of the form
'libgcj-import-DATE'.
- Get a svn checkout of
svn+ssh://gcc.gnu.org/svn/gcc/branches/CLASSPATH/libjava/classpath
this contains "pure" GNU Classpath inside the GCC tree.
- Clean it up and get the files from a new version:
- find classpath -type f | grep -v /\.svn | grep -v /\.cvs
- tar zxf classpath-x.tar.gz
- cp -r classpath-x/* classpath
- Add/Remove files:
- svn status classpath | grep ^\! | cut -c8- | xargs svn remove
- svn status classpath | grep ^\? | cut -c8- | xargs svn add
- If there are any empty directories now they can be removed.
- Update vendor branch
- svn commit classpath
- Note the new revision number (Xrev)
- Get a fresh svn trunk checkout and cd gcc/libjava
- Merge the changes between classpath versions into the trunk.
svn merge -rXrev-1:Xrev \
svn+ssh://gcc.gnu.org/svn/gcc/branches/CLASSPATH/libjava/classpath \
classpath
- Resolve any conflicts pointed out by svn status classpath | grep ^C
- Makefile.in files will be regenerated in the next step.
- Other files should have a "GCJ LOCAL" comment, and/or are mentioned
in the classpath/ChangeLog.gcj file.
(Don't forget to svn resolved files.)
- Use auto* to create configure, Makefile.in, etc
Make sure you have Automake 1.9.3 installed. Exactly that version!
You have to make sure to use the gcc libtool.m4 and gcc lt* scripts
cd .../classpath
cp ../../lt* .

autoheader
automake
rm -rf autom4te.cache
- Test everything first. The simplest way to do this is by overlaying
the checked out classpath on your gcc tree and then doing a build.
- Use 'cvs import' to import. The vendor tag is 'CLASSPATH'. For the
release tag, if this is a released classpath version, use something
like 'classpath-import-VERSION'; otherwise something like
'classpath-import-DATE'.
Be sure to use -ko and -I\!
- Remove any files that were deleted in Classpath
- Run 'scripts/makemake.tcl > sources.am' in the source tree
- Run automake for libgcj
cd ..
scripts/makemake.tcl > sources.am
automake
- Build, fix, till everything works.
Possibly update the gcj/javaprims.h file with scripts/classes.pl
(See below, it can only be done after the first source->bytecode
pass has finished.)
Over time we plan to remove as many of the remaining divergences as
possible.
