Sorry, I just can't fix the problem myself / understand the problem.

[Duality4Y]

happens here too (currently running rolling distribution release)
my gcc version: 8.2.1
Does compile on ubuntu, my guess older compiler.

[Duality4Y]

Can confirm compiles with: gcc-5 (GCC) 5.5.0

[peternewman]

It looks like that line should probably actually be:
memset(&tod.data.toddata.tod,0x00, ARTNET_MAX_UID_COUNT * ARTNET_RDM_UID_WIDTH);

If someone wants to let us know if that works or better yet open a pull request we could get the change merged in.

[dzelionis]

Yes, that's worked like a charm.
Thanks
