Hi there!  
So I’m trying to install pynq under Ubuntu 20. I tried with the [ros:noetic-perception-focal](https://hub.docker.com/layers/ros/library/ros/noetic-perception-focal/images/sha256-0fb955d7218b4c59d889d96f3db475700f000f94e2eeb451a22edd8fb826fc46?context=explore) 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`.

The error message:

Any ideas on how to solve this missing dependency?

Try adding `--sysroot=/` to `CFLAGS` and `CXXFLAGS`

Thanks Peter, I think that got me a step further, but it still breaks:

by the way it’s the same with `sudo -E pip3 install --upgrade --upgrade-strategy only-if-needed pynq` and just `pip3 install pynq`

Try cloning the repository and running `sudo make install` [here](https://github.com/Xilinx/PYNQ/tree/master/sdbuild/packages/libsds/libcma).

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.

```auto
$ pynq get-notebooks pynq-dpu -p .
/home/fpga/.local/lib/python3.8/site-packages/pynq/pl_server/device.py:81: UserWarning: No devices found, is the XRT environment sourced?

```

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.

edit: [the script file I used for instructions](https://github.com/Xilinx/PYNQ/blob/master/sdbuild/packages/xrt/qemu.sh)

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](https://github.com/Xilinx/PYNQ/blob/master/sdbuild/boot/meta-pynq/recipes-bsp/device-tree/files/pynq_xlnk_zynqmp.dtsi) 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.
