4.19 is too old. The lkm code was made to work for <5.4 only recently.
See this change:
darlinghq/darling-newlkm@8153f63

[sergejzr]

Thanks! Is there a compiled binary already?

Kernel modules are always kernel-version specific... You'll need to upgrade to a more recent kernel (+ kernel headers + kernel-devel) first.

Same here, building on GCP. Unfortunately don't work on Linux # 4.19.0-10-cloud-amd64 #1 SMP Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux

Closing due to kernel being too old
