I have to build a module from a third-party that has nothing to do with Yocto.
I want to build this module against the kernel Yocto is giving me.
The Make file for this module has a build command like this:
make -C $(LINUX_DIR) M=`pwd` $(ENV) \
EXTRA_CFLAGS="$(EXTRA_CFLAGS)" modules
Obviously, this command needs to connect with either the Linux source tree or
something like a "kernel-headers" package.
I used the meta-toolchain-sdk recipe to produce an SDK, and I installed it.
Unfortunately, I don't see a "kernel-header" equivalent in there.
This leads me to imagine I must point this command at some sub-tree within the
Yocto output (probably under tmp/sysroots). And, if I want that tree available
elsewhere, I have to package it up into a tarball and transport it.
Usually, Yocto is way ahead of me on these sorts of things, and there's already
a graceful way to deal with this -- I just haven't figure it out yet.
What am I missing?
