Heinz/Lin,

Unfortunately I've only ever built ca2aa against the debian package repo for
channelarchiver.  I just verified that, after making some gcc6 and Base3.15 changes,
it and ca2aa build, and ca2aa passes tests.

I'm not sure of the relationship between https://github.com/EPICSTools/ChannelArchiver
and https://github.com/epicsdeb/channelarchiver.git

The epicsdeb repo originated from a tarfile with a 2.9.2 version number.
Of course, I may not have started with the latest version (back in 2010).
The EPICSTools repo carries a version number 3.0.0 (see make.cfg).  Which suggests
that it's more recent.  Unfortunately, the last tag is from 2008, so it isn't
straightforward for me to say more.

As far as ca2aa is concerned, unless the on disk format has changed
it shouldn't make a difference which version it is built against.
