Hi Mrinal,

 

This was discussed recently in this tech-talk thread:

 

http://www.aps.anl.gov/epics/tech-talk/2017/msg01767.php

 

Andrew Johnson and I suggested to change

     motor_call->termstring = (char) NULL;

to this:

     motor_call->termstring = 0;

I think a new gcc-fix branch was created on github to address this issue, but so far it seems to not have any changes from master, and the problem you are having persists.

 

What version of gcc are you using?

Hi,

I am trying to compile synApps_5_8 with epics_base (base-2.14.12.6). I am getting the following error which is coming from the compilation of motor module I think.

I would appreciate if anyone can help me out here.

Thanks and regards,
