Hi there!
So I’m trying to install pynq under Ubuntu 20. I tried with the ros:noetic-perception-focal docker image and I also tried with an Ubuntu 20 based image running directly on the Ultra96v2 board.
In both cases running pip3 install pynq (with or without sudo) results in a build error. First it misses xf86drm.h, so I install libdrm-dev with apt, and then on the next run it misses drm.h.
Thank you, this also seems to have helped, now the installation for pynq and pynq-dpu complete, but I’ve got a runtime error while trying to add the dpu notebooks.
$ pynq get-notebooks pynq-dpu -p .

I did some digging in the PYNQ repo and found that export XILINX_XRT=/usr is set as part of the XRT package so I set that variable, but of course it makes no sense if XRT is not installed. I tried to follow the steps in qemu.sh for XRT but when I run build.sh it exits without error instantly but the compiled files are nowhere to be found.

I used tag 202020.2.8.743, which is the 2020.2 release, instead of the older one mentioned in the script. Reasoning is that the kernel of my image is also for 2020.2 and I believe it is the version that introduces Ubuntu 20 support.
I’ve no idea what’s going on with XRT - maybe @rock can help?
You have a second issue which is that your kernel or device-tree doesn’t contain the drivers for the /dev/xlnk device. You’ll need to make sure that CONFIG_XILINX_APF is set in your kernel and this fragment is in your device tree.
The output of time XRT_NATIVE_BUILD=no ./build.sh -dbg does not look correct to me. You will need to clear your XRT github repo and redo the build.sh. A correct output should be a long log of cmake build flow, where you can see XRT has been installed by percentage.
