Hello Christophe,
between EPICS Base 3.13 and 3.14 the build system (Makefiles etc.)
changed dramatically. 3.14 has a "compatibility mode" (which must be
switched on explicitly when building base) to allow 3.13 applications to
compile without adapting all the Makefiles and such.
The main distinction between the two is the name of the configuration
directory: .../config for 3.13, .../configure for 3.14.
So - you installed the 3.14 style configuration files into your
extensions area (as the name of the tar reads "Configure"), but you are
obviously trying to compile a 3.13 application (as it tries to find
things in .../config).
Easy solution: Install the tar with the 3.13 style config files (named
"extensionsConfig...") into your extensions area, adapt the
.../config/RELEASE to your needs if necessary, and try again. You should
be able to compile both types of applications now.

Ambitious solution: Develop the application into a "real" 3.14 app.
(There are docs on what to do and how to do this on the EPICS web.) This
might send you through a phase of stress, pain, and frustration - but in
the end you will have learned a lot about the EPICS build system. ;-) If
you are successful and feed back your changes to the original authors,
they will love and praise you in return. (How christmassy that sounds ...)
Good luck - whatever option you choose!

Hello,
I am trying to set up an extensions directory where I would store
applications like the alarm handler.

For that, I have installed the following tar file :
http://www.aps.anl.gov/epics/download/extensions/extensionsConfigure_20040406.tar.gz 

Then, in the src directory I put the alarm handler package.

When I launch a compilation from the extension directory, I have the
following message :
Makefile:4: config/CONFIG_EXTENSIONS: No such file or directory
Makefile:6: config/RULES_TOP: No such file or directory
make: *** No rule to make target `config/RULES_TOP'.  Stop.
Does anybody know what's going on ? Are some files missing ?
Thanks
Christophe
