Hi Liang,

The main problem is that when you built stepmotor.dbd you did not include base.dbd. That is why all of the records from base (aSub, aai, aao, ai, ao, etc.) are undefined.

The other problem is that it looks like you included stream.dbd before calcSupport.dbd. calcSupport.dbd must come before stream.dbd.

Hi all,

I met a question. I use EPICS 3.15.8 ,linux os.

I want to use a driver in github https://github.com/iattarla/StepmotorEpics.

But failed.Here is the output of st.cmd. I have no idea about it.

***********************************************************

I doubt:

a) I use epics 3.15.8,but the use 3.14 or 3.13 ,does it matter?

b) why so many registerRecordDeviceDriver failed error.

Any suggestion was appreciate.

Regards,

Liang
