I am building Linux Image using Yoctobuild system on Ubuntu 18.04 host machine. I am following steps provided over here. I am building for Colibri iMX6ULL computer-on-module. However, my build has failed and it is showing errors given below
declaration of ‘memfd_create’ follows non-static declaration

Can someone help me? I can't switch to ubuntu 16.04 but I think it should be working with my system as well.
This is a known issue at Toradex and is on the Roadmap, see issue #36657.
Fixes are already in the upstream layers, and we have updated our BSP repo. You can try this branch by using the LinuxImageV2.7-integration branch.
