I think that I figured out the problem, although you may not like the solution.
Essentially, the problem is the RPi OS used:
-
When I used BULLSEYE OS, I got the same errors as shown by xiasha.
-
But if I used BUSTER OS, then no problem at all with “make” and “sudo make install” - see pictures below:
So for now, you will need to stay with BUSTER if you want to use DXL SDK, therefore some new features from BULLSEYES are not available.
I am mentioning this issue to @Jonathon and @willson too, so that they know what to look for when it is time to upgrade DXL SDK to BULLSEYE OS.
