9# You're probably looking here thinking you need to create some new copy
10# of linux-libc-headers since you have your own custom kernel. To put
11# this simply, you DO NOT.
12#
13# Why? These headers are used to build the libc. If you customise the
14# headers you are customising the libc and the libc becomes machine
15# specific. Most people do not add custom libc extensions to the kernel
16# and have a machine specific libc.
17#
18# But you have some kernel headers you need for some driver? That is fine
19# but get them from STAGING_KERNEL_DIR where the kernel installs itself.
20# This will make the package using them machine specific but this is much
Patrick Williamsc0f7c042017-02-23 20:41:17 -060021# better than having a machine specific C library. This does mean your
22# recipe needs a
23# do_configure[depends] += "virtual/kernel:do_shared_workdir"
24# but again, that is fine and makes total sense.
Patrick Williamsc124f4f2015-09-15 14:41:29 -050025#
26# There can also be a case where your kernel extremely old and you want
27# an older libc ABI for that old kernel. The headers installed by this
28# recipe should still be a standard mainline kernel, not your own custom
29# one.
