recipe-sysroot doesn't contain kernel patch

recipe-sysroot doesn't contain kernel patch

Hello,

I’m currently developing a custom yocto layer in AGL and did a kernel patch to contain IFLA_CAN_TERMINATION macro in the linux/can/netlink.h file since the kernel I’m using doesn’t contain it.
The problem is that in the output of the kernel compilation the patch was applied, but when bitbake compiles systemd it raises an error saying there is no IFLA_CAN_TERMINATION declared. Checked recipe-sysroot and it isn’t patched.
What can be the source of the problem?

Thank you.

Cumprimentos / Best regards,

The recipe providing the kernel headers to the libc is
linux-libc-headers, not the kernel recipe.

right and you want to really take a hard look at why your userspace
depends on customized UAPIs
