Unable to build edk2 sources

I’m trying to compile an edk2 build to flash on my AGX Orin, but have hit a blocker. I am compiling an Ubuntu 18.04 Docker image (https://github.com/makinbacon21/nvidia-edk2-docker) following each official step up to the build script (edk2-nvidia/Platform/NVIDIA/Jetson/build.sh), which I run manually. The script fails on “Loading Plugins”:

Exception: One or more plugins failed to load.

On my Fedora 36 Server (natively, not in docker), I get much further, but several issues arise (presumably due to newer toolchain):

^ Context: the error returned is 2 (from make), due to a bunch of build errors


Please noted that Orin uses Ubuntu 20.04.

Based on the error, the failure is caused by some missing libraries for python 3.6.
However, the default python version of Ubuntu 20.04 should be python 3.8.10.

Could you check with the edk2 team to see if they support JetPack 5 first?


Ah I could have sworn it specifically stated to use 18.04…possibly the instructions were updated as they now read 20.04. Allow me to try.

Also fwiw I’m using nvidia’s edk2, not stock, and am cross compiling from a docker container rather than compiling directly on JetPack.

Thanks for the help!

@AastaLLL re: last comment, r34.1 branch instructions still say to use 18.04 but the main branch was updated to recommend 20.04. Clearly 20.04 is needed on either. Thanks!

Well if anyone is interested, here is my now-fully-functional container:


Sorry that the statement is confusing.
For Orin, which uses r34 or 35, it is Ubuntu 20.04.
The desktop, which is used for cross-compiling, can be Ubuntu 18.04. Need to be Ubuntu 20.04 as well.

Based on the GitHub, does everything work well already?

That actually seems to be incorrect. As it turns out (and the GitHub has been updated to verify), cross-compiling edk2 needs Ubuntu 20.04 for its python version. 18.04, as you had said correctly before, doesn’t have the right version of python. Now everything seems to work well.


Thanks for correcting this.
Will update the previous comment as well.
