[Cerowrt-devel] kmod_sched_pie falis to compile with implicit declaration error in openwrt trunk for x86

[Ignatius Rivaldi]

I tried to build openwrt with Cake support according to this page:
https://www.bufferbloat.net/projects/codel/wiki/Cake/ , then I run make,
and it crashes. I then run make -j1 V=s as instructed by the make process,
and  is the last error message:
