Hi John,

First, I don't think the scalcout record depends on the sseq record.

Second, EPICS base changed and you need a copy that is compatible. Here's an excerpt from the current sseqRecord.c:

#if LT_EPICSBASE(3,16,0,1)

      pR = (sseqRecord *)(plink->value.pv_link.precord);

#else

      pR = (sseqRecord *)(plink->precord);

#endif

All,

I'm attempting to build the scalcout record which depends on the sseq record. Building sseqRecord.c gives:

../sseqRecord.c:537:49: error: ‘struct pv_link’ has no member named ‘precord’

Line 537 reads:

      pR = (sseqRecord *)(plink->value.pv_link.precord);

The following compiles but I have no idea if the semantics are correct:

        pR = (sseqRecord *)(plink->precord);

Can anyone provide guidance?

Thanks,

John Sinclair
