# You're probably looking here thinking you need to create some new copy
|
# of linux-libc-headers since you have your own custom kernel. To put
|
# this simply, you DO NOT.
|
#
|
# Why? These headers are used to build the libc. If you customise the
|
# headers you are customising the libc and the libc becomes machine
|
# specific. Most people do not add custom libc extensions to the kernel
|
# and have a machine specific libc.
|
#
|
# But you have some kernel headers you need for some driver? That is fine
|
# but get them from STAGING_KERNEL_BUILDDIR where the kernel installs itself.
|
# This will make the package using them machine specific but this is much
|
# better than having a machine specific C library. This does mean your
|
# recipe needs a
|
# do_configure[depends] += "virtual/kernel:do_shared_workdir"
|
# but again, that is fine and makes total sense.
|
#
|
# There can also be a case where your kernel extremely old and you want
|
# an older libc ABI for that old kernel. The headers installed by this
|
# recipe should still be a standard mainline kernel, not your own custom
|
# one.
|
