lxc_3.0.1 causing build failure with Yocto + Raspberrypi

[satishnaidu]

Hi Team,

I am trying to build LXC as part of OpenWRT+RaspberryPI environment, but I am facing issues during the build.

I am able to build the lxc_2.0.8 with the same configuration, I am only getting this error after upgrading the lxc version to 3.0.1

Please let me know how to proceed further on this.

Thanks & Regards,
