Build breakage - coreboot

11 Sep 2021


      Hi,
I'm running into a problem following the steps at https://doc.coreboot.org/tutorial/part1.html on an Ubuntu 21.04 based system. The host compiler is gcc 10.3 and apparently CoreBoot has installed gcc 8.3.0 for its own usage but seems to be missing some required parts.
Everything is good up until:
