11# You're probably looking here thinking you need to create some new copy
12# of linux-libc-headers since you have your own custom kernel. To put
13# this simply, you DO NOT.
14#
15# Why? These headers are used to build the libc. If you customise the
16# headers you are customising the libc and the libc becomes machine
17# specific. Most people do not add custom libc extensions to the kernel
18# and have a machine specific libc.
19#
20# But you have some kernel headers you need for some driver? That is fine
Andrew Geisslerc9f78652020-09-18 14:11:35 -050021# but get them from STAGING_KERNEL_BUILDDIR where the kernel installs itself.
Patrick Williamsc124f4f2015-09-15 14:41:29 -050022# This will make the package using them machine specific but this is much
Patrick Williamsc0f7c042017-02-23 20:41:17 -060023# better than having a machine specific C library. This does mean your
24# recipe needs a
25# do_configure[depends] += "virtual/kernel:do_shared_workdir"
26# but again, that is fine and makes total sense.
Patrick Williamsc124f4f2015-09-15 14:41:29 -050027#
28# There can also be a case where your kernel extremely old and you want
29# an older libc ABI for that old kernel. The headers installed by this
30# recipe should still be a standard mainline kernel, not your own custom
31# one.
