Not sure how to figure this one out. Let me know if there are other details needed, but certainly appreciate someone who knows looking at it!

Hello @mickdw2015 was working on setting up the same in my lab. Facing the same issue, was wondering what is the fix for the first error ? "/opt/lab/flows/ipt-netflow/compat.h:777:48: error: missing binary operator before token "(""

And has anyone else found the fix for the second issue , any help is appreciated, thanks!

Try this: https://github.com/kalamlacki/ipt-netflow I reverted one change which should never be released.

For others reference: Below was the fix for the first error https://github.com/aabc/ipt-netflow/issues/195
