| 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 |
| 21 | # better than having a machine specific C library. This does mean your |
| 22 | # recipe needs a DEPENDS += "virtual/kernel" but again, that is fine and |
| 23 | # makes total sense. |
| 24 | # |
| 25 | # There can also be a case where your kernel extremely old and you want |
| 26 | # an older libc ABI for that old kernel. The headers installed by this |
| 27 | # recipe should still be a standard mainline kernel, not your own custom |
| 28 | # one. |
