Hello Vishnu,

 

The scalcout record type is in the "calc" module which is part of SynApps.

You can either build StreamDevice without support for scalcout or you have to add the calc module to your project.

Hi,

    I am using stream device in my application.

with stream device i am getting error below

dbd  order in make file is

 

# lcpc.dbd will include these files:

lcpc_DBD += base.dbd

lcpc_DBD += xxxSupport.dbd

lcpc_DBD += dbSub.dbd

lcpc_DBD += devlcpcVersion.dbd

lcpc_DBD += lcpcHello.dbd

lcpc_DBD += initTrace.dbd

lcpc_DBD += s7nodave.dbd

lcpc_DBD += asyn.dbd

lcpc_DBD += drvAsynSerialPort.dbd

lcpc_DBD += drvAsynIPPort.dbd

lcpc_DBD += stream.dbd

lcpc_DBD += modbusSupport.dbd

 

 

what can be the reason for error?

 

Thanks
