OK, have the problems with compiling the Channel Archiver looking

Now, to move on to other things- edm

I'm trying to setup everything so that the binaries reside in /usr/
local/EPICS/bin/linux-x86.

Usually, EPICS 'base' and 'extensions' have their own subtree and don't
end up in the same bin,lib,include,doc,...
The includes install in /usr/local/EPICS/extension/include/edm.
Shouldn't they have gone into /usr/local/EPICS/include?

Exactly the thing: extensions/include (and usually also a base/include).
When you try to start the program, you get:

*------------------------

home/daviddu/local/src/EPICS/extensions/src/edm/baselib/O.linux-x86/
libEdmBase.so: cannot open shared object file: No such file or
directory

*------------------------

Where'd that come from? libEdmBase.so and libEdmBase.a are in /usr/
local/EPICS/lib/linux-x86.

You tell EDM where to load those via
and env. variable EDMOBJECTS that points to a file which lists
the objects and shared libs where they reside.
edm/setup/setup.sh is meant to help to create those files
and set the env. vars, but I think most sites end up
doing something else manually to pick which objects they
want to use.
