• How_to_import_GNU_Classpath_into_GCJ

• - Get a svn checkout of

  svn+ssh://gcc.gnu.org/svn/gcc/branches/CLASSPATH/libjava/classpath

• this contains "pure" GNU Classpath.

• - 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

• - Update vendor branch

  svn commit classpath

• - Note the new revision number (Xrev) - Get a fresh gcc 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 later - Other files should have a "GCJ LOCAL" comment, or are mentioned

  • in the classpath/ChangeLog.gcj file. (Don't forget to svn resolved files.)
  - Use auto* to (re)create configure, Makefile.in, etc
  • (Make sure you have Automake 1.9.3 installed. Exactly that version!)

  cd classpath
  cp ../../lt* .
  cp ../../config.sub ../../config.guess .
  aclocal -I m4 -I ../..
  autoconf
  autoheader
  automake
  rm -rf autom4te.cache
  cd ..
  scripts/makemake.tcl > sources.am
  automake

• - Build, fix, insert new override files, etc till everything works.
  • Possibly update the gcj/javaprims.h file with scripts/classes.pl

    (See HACKING, it can only be done after the first source->bytecode

    • pass has finished.)
