If you are installing GNU libc on a Linux system, you need to have
|
||||
the header files from a 2.2 or newer kernel around for reference. For
|
||||
some architectures, like ia64, sh and hppa, you need at least headers
|

from kernel 2.3.99 (sh and hppa) or 2.4.0 (ia64). You do not need to
|
||||
use that kernel, just have its headers where glibc can access at them.
|
||||
The easiest way to do this is to unpack it in a directory such as
|
||||
`/usr/src/linux-2.2.1'. In that directory, run `make config' and
|
||||
accept all the defaults. Then run `make include/linux/version.h'.
