Building Docker causes error about openmvg HOT 2 OPEN

Can you share in which folder are you?
You should run this in a git clone

from openmvg.

Thank you, @pmoulon , for your quick responses! Very much appreciated!

So from what I understand from your previous comment I should first git clone --recursive [the-repo] – --recursive being the keyword here. Because previously I did NOT use --recursive.

OK. I ran git clone --recursive [repo] and then changed into that openMVG folder in order to runt he Docker command.
However, I still get an error, which you can see in the attached text file.

What I am still wondering about is: why does the docker solution try to install something into the local /opt folder? It is a Docker app and IMO shouldn't do that. (BTW: It does not, and that seems to be the reason why the error happens; I have a feeling that I should run the command as sudo – but, honestly, I do not want Docker to install anything outside of its container.)
