Hi Ole,

               I'm hitting the same issue.

               Running the build with V=2 doesn't actually produce more output.

Which means my logs are the same as Sirshak's. But in any case I attached the 
output from a run with V=2.

I can provide other info if there's more you need - or you can try accessing 
one of our ThunderX's in the FD.io lab if you have access.

Thanks,
Juraj

Juraj,

Without a make log this is just a guessing game.

Cheers
Ole

Hi Sirshak and Ole,

I'm hitting the same issue. The build fails on a clean repository, but the 
subsequent build works fine, which is fine for local builds, but still needs to 
be fixed.

Running the build with V=2 doesn't actually produce more output. There one more 
bit of information I can provide - this behavior is present on Ubuntu1804 
(4.15.0-38-generic), but builds on Ubuntu1604 (4.4.0-138-generic) work right 
away, which explains why CI didn't catch it.

This is the patch that introduced the issue: https://gerrit.fd.io/r/#/c/16109/

Sirshak,

Can you touch one of the .api files and rebuild with V=2 and show the output of 
that?
It might be that vppapigen fails for some reason (or try to run it manually and 
see).
