You are right, the registrar function was missing.

1/ Compile the snl program to turn it into a c program
   (In this program there is a epicsExportRegistrar command )
2/ Include the c source from 1 into the IOC code by editing the IOC
Makefile
3/ compile
4/ start the IOC, with a dbd file that includes the registrar function
5/ ... it works ...

I was actually starting the ioc executable without doing a
dbloaddatabase(<... dbd file>). So the registrar function was not
executed.

Thanks,
