OK, Maurizio, I think I have an idea now where you're at.

Background and bottom line of Mark Rivers' statement:

You will want to keep library-type (aka "support") modules, e.g. EPICS

Base as well as other record, device, and driver support modules, apart

from your application (aka "ioc") modules: in the end you will have many

ioc applications that need the same external module (in this case the

epid record), and you certainly don't want to keep many copies of the

the same library source code distributed everywhere.

So - even if it sounds more complicated at the moment - please follow

the approach that Mark suggests: install and compile the std module from

synApps in a separate location (i.e. NOT in the same structure as your

ioc app), and make your ioc app structure point to it by adding the

STD=<location> line in your app's .../configure/RELEASE file.

As soon as you add your second and third ioc app structure, more

external modules, and maybe another version of synApps, you will easily

see why it was a good idea to start with the clean structure from the

very beginning instead of mixing libraries and applications.

Good luck!

Hello Ralph,
thanks a lot for your help.

I tried to modify the file as you told me, but i have the same problem.
The epid record consists of these files:
- devEpidSoft.c , epidRecord.c and epidRecord.dbd in .../src
- mono_pid_control.db and pid_control.db in ..../Db

I created a new ioc with the MakeBaseApp script and i put these file
in the corresponding directories, i modified the Makefile in .../src
adding the following commands:
1) testPID_DBD += epidRecord.dbd
2) testPID_LIBS += epidRecord (before the $(EPICS_BASE_IOC_LIBS) )
3) testPID_LIBS += devEpidSoft (before the $(EPICS_BASE_IOC_LIBS) )

i changed the Makefile in the .../testPIDApp/Db filder adding the db file:
DB += mono_pid_control.db
DB += pid_control.db

and i modified the RELEASE file ad you suggested:
EPID=/home/monti/pid/test/testPIDApp/src

after this i tried to compile first in the ../configure  and then in
the top directory (i made a make clean uninstall before the last
recompile).
Did i forget to do something?
