For an application I need to upload a large number of analogue values to a

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?

Hi:


I know nothing about the aaiRecord, but the message indicates
that the database processor read your aaiRecord.dbd file,
knows about the aai record and its fields, yet fails to locate the
library code that actually implements the _device_ support for your aai.

How did you set the 'DTYP' field of your record?

For example, if you set it to
   field("DTYP", "XYZ")
then your dbd file would have to include something like
   device(aai, INST_IO, devAaiXYZ,"XYZ")
and your application would somehow have to include the binary that
implements devAaiXYZ.
