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!
Ralph
