Hello Lewis, John, Christoph,
thanks for your comments and insights - at this moment, we were able to have edm built for Debian 9 internally using the mentioned fork. The package should be available in our stretch staging mirror once that is synchronized (overnight). There are no plans to use it as a baseline viewer solution, just an accommodation for a specific case (building and publishing it is a good bonus). Few notes:
1) I tested that it launches, but no further - will be some time to verify it on some actual screen collection.
2) The patch queue has a patch that has no ownership information.
3) As Lewis suggested, a pull request to
epicsdeb edm may be a good idea. There is an outstanding
upstream branch PR which doesn't include pristine-tar and debian/ stuff and is likely to be superseded.
Regards!
Anton.
