[SOLVED] Unable to build ZFS on 1.4

[walterw]

When attempting to build ZFS on release-1.4, I am getting this error:

 

checking whether modules can be built... no
configure: error: *** Unable to build an empty module.

emerge zfs -vp

[ebuild  N     ] sys-fs/zfs-kmod-0.8.1::core-kit  USE="-custom-cflags -debug -rootfs" 0 KiB
[ebuild  N     ] sys-fs/zfs-0.8.1::core-kit  USE="python -custom-cflags -debug (-kernel-builtin) -rootfs -split-usr -static-libs -test-suite" PYTHON_TARGETS="python2_7 python3_7 -python3_5 -python3_6" 0 KiB

 

Even though I have build a kernel and have already booted to it (outside of this chrooted env), I feel like there is something not quite right with my /usr/src directory possibly.

 

Any ideas?

I must have had an old kernel built, so the kernel source directory was not configured properly.
