Make fails on Ubuntu 16.04

[subsecond]

I am trying to run BFD on FRR under Ubuntu 16.04 and apparently need PTM in order to get it to work. However, make fails with the following error:

root@lab-r1:mgmt:~/ptm# make

Is that something that can be fixed easily or should we look for a different implementation of BFD?

This patch/change will get you past this problem .. while a cleaner fix is put in

Thanks, that actually worked while still producing the same warnings.

However, PTM does not seem to run on Ubuntu 16.04 without making further code changes. I found the following instructions for 14.04 that show how much customization needs to be done in order to get PTM working:

Are there any plans to officially support Ubuntu as well? Currently, the only way to get BFD running in combination with FRR (frrouting.org) seems to be by using PTM.

What errors did you see ? There is no official support for the github project at this point, but if you do get this working and it needs patches we will be happy to take them.

The 14.04 issues are due to older lldp and ptm library dependencies. Should not happen on 16.04, can you paste the actual issue you saw ? also a dpkg -l would be useful
