I had a hard time getting any clue that the CVS repo was abandoned. Now finally
found http://savannah.gnu.org/git/?group=classpath which is not that obvious
when you start at classpath.org.

Further, it looks like classpath did bump the requirement on autoconf to 2.69,
and didn't even bother to document that (m4/iconv.m4 requires macros only found
in 2.69).  classpath itself pretends to require 2.63.

GCC has 2.64, and won't change for the next release. Any hint how to handle this
properly?

no, looks like the iconv.m4 file was included without including lib-ld.m4,
lib-link.m4 and lib-prefix.m4, now copied from gettext, and the configure
scripts can be regenerated.

Ah, sorry. That must make it look like GNU Classpath is even less active
than it is :{ It is good to keep the CVS repo around for some time, just
for the historical information like branches and tags that didn't
transfer to the git repo. But not if people get confused by it and don't
know where the current sources are. Maybe we should add a file to CVS
"README_MOVED_TO_GIT" with information where the actively maintained
sources are now found?

Cheers,

Mark

But that's not supposed to happen, surely.  The transfer to GIT isn't
complete until the tags have been copied.

There is the classpath git tree at
http://icedtea.classpath.org/mirror/git/classpath/classpath/
which does have all that. But it only has the CVS part of the history.
The trick now is to figure out how to merge that git tree with the
official GNU Classpath git tree on savannah. Sadly my git foo isn't
strong enough to figure that out :{
So any hints or tips from some more experienced git users appreciated.

Thanks,

Mark

The mirror git tree is where we branched off our current development
tree. You should be able to just push the tags to the tree on
Savannah. Andi?

aha, they are indeed mostly the same, though there is one commit that
doesn't match (the top one in the mirror, is also present on savannah
but under another commit id) which makes things slightly confusing. So
in principle git push --tags should do it, but how about the branches?

Thanks,

Mark

Try reading the mailing list.  It's been discussed at length at the time
and there's been discussion of commits to it since.

Classpath works with 2.63 on RHEL6.  That's why I lowered it.

What macros are you referring to?  iconv.m4 is dated 2002 in the header.
