Hi Ferruh, Sorry, I forgot to mention, Yes, I was compiling with -Denable_kmods=true.
I just partially found a root cause. The target system Photon OS (It VMware distro) It has 4 kernels variation regular, RT, ESX, security. ( I was using ESX variation that optimized for ESXi but it looks like something is disabled in the kernel that prevents KNI to compile) when I use a regular kernel source tree, it does compile. I was trying to figure out what KNI actually requires from the kernel source tree or what instrumentation I can use it to see the more verbose errors. ninja -v doesn't really provide details.
