compilation terminated.

Hi @rodb70, yes, the Linux port of the library is not completed at this time. We will have this working in the very near future. You can keep an eye on https://jira.etcconnect.com/browse/RDMNET-20 or on the docs to indicate Linux as a supported platform; since we have a low issue count right now, I'll also go ahead and just leave this one open and close it when we have Linux support.

No problem close as you see fit.

As of the latest tag baseline v0.3.0.10, the library and example applications should be buildable on Linux. Tested on Ubuntu 18.04 and 20.04.
