NSO - IOS-XE AAA yang model compiling end with silent error

[LoicChabert27318]

Hi !

I'm currently using Cisco NSO product to develop Ipsec tunnels gateway. I have compile all mantadory yang models, extracted from netconf-ned-builder tool.

Unfortunatly, when i add AAA yang models, NED build process end with an error, but without any details. How can i get more details about the error ?

Please find more details below:

NSO version: 5.7.1

Netconf target: CSR1000v 17.3.3

Build error:

I have tried to add more debug on makefile, but only the yanger command is displayed, without more details:

Only the AAA model end with this error.

Any hints concerning this issue ?

Hello,

I tried on NSO 5.7.2.1 . I got the same error but it compile on NSO 5.8.

 Can you try on NSO 5.8 ? 

One of the solution will be to use NSO 5.8 ..

[LoicChabert27318]

Hi,

Indeed, it's works with 5.8. Maybe a yang compilation bug on 5.7.x ... I will open a case on BST and ask for a backport of code.

Regards.

[LoicChabert27318 · Accepted solution]

To be more specific, it's works too on NSO 5.7.4.

As mentionned on 5.7.4, a new yanger version is used, and solve yang compilations issues.

After opening a case on BST, they recommends to use as minimal version 5.7.4. I think NSO team will not backport changes on other versions.
