NSO 5.5.4 Yang derive from cisco-ios

[tsiemers1]

Trying to fix a package to work that seems to have broken with either NSO 5.5 or the Cisco ned for ios (6.77). When working I had this in the yang which made sure the leafref only ran when it was derived from cisco-ios ned.

leaf interfaceXEName {
      when
        "derived-from-or-self(/ncs:devices/ncs:device[ncs:name=current()/../deviceName]/ncs:device-type/ncs:cli/ncs:ned-id, 'cisco-ios-cli:cisco-ios-cli')";
      description
        "List of GigabitEthernet interfaces specific to cisco-ios-cli ned devices";

      type leafref {
        path "/ncs:devices/ncs:device[ncs:name=current()/../deviceName]/ncs:config/ios:interface/ios:GigabitEthernet/ios:name";
      }
    }

This gives the following error when running 'make clean all'

make: *** [Makefile:26: ../load-dir/formItential.fxs] Error 1

What method is available to run this? Full yang and Makefile below.

The error message in your description is showing what Makefile target it was that failed. But it doesn't show the actual failure. Did you get any more output or error messages before the output "make: *** [Makefile:26: ../load-dir/formItential.fxs] Error 1"? I can see from your Makefile that the compiler is called with the --fail-on-warning flag, so it might have been a warning that failed it.

That was it. Once I deleted --fail-on-warning from the Makefile it complied and worked in NSO. No output on the failure was given but I'll try to debug the make command and see.

Thanks
