change your compiler parameters so warnings are not treated as errors. There should be a environment variable you can set.

Hi bkt
I'm also trying to install ethercat on LMDE6 but I can't get started. The process I went through is the same as what you found on the forum.

Unable to locate package ethercat-master
Unable to locate package libethercat-dev

Can you share your experience and specific steps for successful installation?
Thank you so much!
