I think the best way out for you is to set up a container with a supported older distribution. Usually you need an older gcc version from the host machine, so the container will have that.

Hi,

Has anyone tried to build yocto 2.6 on Ubuntu 20.04?

I know it's not supported, but it's a major task for me to upgrade to yocto 3.x.

I tried it myself and it fails on building qemu-native.

I wonder if anyone worked around this.

Thanks,

Jacob
