Remark Jetson Nano / 22.04 / CUDA / GCC 8.x

[nmaas87]

Dear all,
thanks for the awesome repo.
Just a remark for people coming after me: I built an image for the 4 GB / B01 / 300er revision Jetson Nano with Ubuntu 22.04 (because 24.04 is not supported with Jetpack 32.x/latest for Jetson Nano). Just a remark: Ubuntu 22.04 uses GCC 11.4.x, while nvcc needs GCC 8.x, meaning if you build with Ubuntu 22.04, you won't be able to use nvcc to compile your own CUDA code on the hardware, unless you get GCC 8 installed on the system. I have not tried to run existing CUDA kernels on the Jetson, but found it to be noteworthy. Never the less - awesome that you got it working and slimed down, would have loved to see 24.04 and above working with Jetson Nano, but looks like this hardware will be filling up landslides soon as Nvidia does not want to keep on supporting their hardware, but just keep on selling new stuff. There is probably a leason to be learned...
Thanks guys! 👍🏻

you can use Ubuntu 24.04 with some tweaks from nintendo switch repos

Scripts image they are used from raspberry pi image.

For Cuda, you're right, you need to have GCC 8 or lower installed on your system. What I do is have two or more versions on the system and then use sudo update-alternatives to point to two different versions in g++ or gcc, allowing me to switch between them as needed.
