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
