Stefan,
Every record, device or driver support consists of two parts: Its
database definition (ends up as part of an ascii file that is read by
the IOC at startup) and the matching code (some object code which is
loaded into a support library that the IOC loads).
While you seem to have successfully added the database definition stuff,
your support library still misses part of the matching object code.
Make sure that the Makefile in addition to adding the aaiRecord.dbd not
only includes the record support object, but also at least the soft
device support for it. (Take a look at baseLIBOBJS or at the example
application Makefile to see how this is achieved.)
BTW: The AAI record is an input record (that's what the 'i' stands for).
If you want to get values /to/ a device, EPICS would regard this an
/output/ operation, so the appropriate record might rather be the AAO
record. But I'm just wildly guessing ... sorry if this was too obvious.
Good luck!
Ralph

For an application I need to upload a large number of analogue values to a
device. Therefore the AAI record seems to suit perfect.
I use EPICS R3.14.6 on a linux machine.
As being not such an experienced user it is not clear for me how to add the
support for this record to my application.
I've already added the line:
	DCCC_DBD += aaiRecord.dbd
After the "DCCC_DBD += base.dbd" line in the "DCCCApp/src/Makefile" file.
When running the application I get the following message from the IOC
console:
	filename="../recGbl.c" line number=88
	Missing device support entry table PV: DCCC:wavgen:waveform  aai:
init_record
What actions do I have to take to get the support for this record type
running?
Thanks in advance,
Stefan
