Bulgarian Gay Organization? Sorry, googling for b.g.o is dangerous. :) |

Actually I do, but I don't go anywhere near the kernel so I wasn't sure of the |
| 19 |
relationship between glibc and the kernel interfaces. I'm just wondering if |
| 20 |
/usr/include/linux is ever incompatible with my kernel, and what to do about it if |
| 21 |
it is. |

I see that, for example, |
| 30 |
|
| 31 |
msoulier@anton:~$ equery belongs /usr/include/linux/quota.h |
| 32 |
[ Searching for file(s) /usr/include/linux/quota.h in *... ] |
| 33 |
sys-kernel/linux-headers-2.6.23-r3 (/usr/include/linux/quota.h) |
| 34 |
|
| 35 |
ulier@anton:~$ uname -a |
| 36 |
Linux anton 2.6.25-gentoo-r8 #9 Sun Nov 23 19:14:08 EST 2008 i686 AMD |
| 37 |
Athlon(tm) XP 1700+ AuthenticAMD GNU/Linux |

So slightly off but compatible. At some point a newer glibc would simply fail |
| 40 |
to build if it's incompatible then, I assume? |
| 41 |
|
| 42 |
Looking on a CentOS box I see that they package that directory in a package |
| 43 |
called glibc-kernheaders. Makes sense... |
| 44 |

Thanks, |
