I had to move from Jessie to Stretch as kernel 5.15.49 requires gcc 5.x version (Jessie had 4.9 version Stretch 6.x). I decided to try the ZSTD module compression option in 5.15.x. I ensured to apt-get install zstd
beforehand.
Using make bindeb-pkg
it gets all the way past compiling and signing the modules but then errors out and you can see on the screen the zstd output saying incorrect parameters
then giving a sample of what the parameters should be. So clearly it's executing the compressor but it doesn't like whatever parameters kbuild is sending it?
Is this a known issue? Is there an easy fix for this?
TIA!!
