| # 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. |
| # |
