Official moOde 7.1.0 support thread

[eddywouldgo]

I'm working on a new build of 7.1 on a Pi 3B+ and keep getting stuck in the same place. Am using the direct build method and everything goes well until I get down to Component 10, where I keep getting the message below. Have rebooted a number of times with same result. For what it's worth, I do not yet have a DAC attached. I haven't gotten one yet, just going one step at a time. Not sure if that matters.

Any advice appreciated. Thanks.

That file is in the sources zip for the current version of mosbuild.

After realizing that I was misinterpreting the install process, I went to the USB SD card method. The exact same error persists, even though the file shows up (and is not empty) if I  pull the sd card and look at it on my laptop, as shown here. Where might I or the process be going wrong? I have a fairly complete moslog record for the latest installation attempt, but the forum seems not to allow txt or rtf file attachments.
Thanks.
