Probably the current epics-base is not working with 4.10.2 any longer?<br>
<br>
The pthread_getschedparam() was introduced to allow epics-base to<br>
compile properly with the 4.10 HEAD (pending 4.10.3 release). Use the<br>
4.10 HEAD instead of 4.10.2 release/tag and see how the process goes<br>
instead.</div>
