I've tried to disable KNI but it same issue. Any ideas what might be a root cause.

Can you confirm you have kernel source installed in your system? Or to be more specific, does '/usr/src/linux-headers-5.10.52-3.ph4-esx' patch has kernel source code? And can you please share your full commands for build? Cheers, ferruh ^ permalink raw reply [flat|nested] 3+ messages in thread

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.
