Deadline for this is indeed August 1st - after that we won't be able to post new app versions without arm64. Existing app / last version published won't be delisted until later this year (I believe November) > Always having the idea that the BT download issue could be Qt related, my > first plan was to build against a newer Qt, as reporting bugs to Qt is likely > not going to be very successful when running older Qt version. > > So, step 1.

But I know that last time I documented this reasonably well so I hope that once you have a working process I can manage to create a new Docker image for it fairly quickly. Thank you so much for working on this. That's a huge deal for the project. /D _______________________________________________ subsurface mailing list [email protected] http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
