What files need to be created?

• An IDL file containing the definition of a struct the NC will send/receive. If using simple CORBA types, this is not necessary.

• A header/implementation each for the derived supplier and consumer. This is not necessary for the SimpleSupplier or SimpleConsumer classes.

Makefile Targets

The only special thing that must be done is linking in the acsnc library.

Done quite simply actually:

xxx_LIBS = acsnc

where xxx_ is replaced by the name of the library or executable you’re

trying to create.

Learn From Others’ Mistakes

• If it at all possible, do not thread Suppliers or Consumers. If this is done, there may be be problems restarting containers.
