Hi,
I am following the SDK build instructions here
https://wiki.luckfox.com/Luckfox-Lyra/SDK/
I am on Ubuntu 24.04 LTS x86_64 host and am using configuration option 8. luckfox_lyra_ultra-w_ubuntu_emmc_defconfig
When I run `sudo ./build.sh` I get the following build failure.

Can anybody please advise?

Thanks, Alex
