HI,

try to create NTTable :

 NTTableBuilderPtr builder = NTTable::createBuilder();
    
    PVStructurePtr pvStructure = builder->
            addColumn("ts", pvInt)->
            addColumn("X", pvDouble)->
            addColumn("Y", pvDouble)->
            addColumn("Z", pvDouble)->
            addDescriptor()->
            addAlarm()->
            addTimeStamp()->
            createPVStructure();

Unfortunately, I always end up with "core-dump” on the RTEMS-system.

I have not understood yet how to specify the length for the four arrays (pvInt, pvDouble [X,Y,Z] ) connected to the 4 columns.
I thought I had to add an array structure to the 4 columns. But I found nothing in the nttable.h file how to do that.
Every note is welcome as always.

Danke,
Heinz
