|
<para>The host must be running at least a 2.6.2 kernel compiled with
|
|
GCC-3.0 or higher. There are two main reasons for this high
|
|
requirement. First, the Native POSIX Threading Library (NPTL)
|
|
test suite will segfault if the host's kernel has not been compiled with
|
|
GCC-3.0 or a later version. Secondly, the 2.6.2 or later version of
|
|
the kernel is required for the use of Udev. Udev creates devices
|
|
dynamically by reading from the <systemitem
|
|
class="filesystem">sysfs</systemitem> file system. However, support
|
|
for this filesystem has only recently been implemented in most of
|
|
the kernel drivers. We must be sure that all critical system devices
|
|
get created properly.</para>
|
|
|
|
<para>In order to determine whether the host kernel meets the
|
|
requirements outlined above, run the following command:</para>
|
|
|
|
<screen><userinput>cat /proc/version</userinput></screen>
|
|
|
|
<para>This will produce output similar to:</para>
|
|
|
|
<screen><computeroutput>Linux version 2.6.2 (user@host) (gcc version 3.4.0) #1
|
|
Tue Apr 20 21:22:18 GMT 2004</computeroutput></screen>
|
|
|
|
<para>If the results of the above command state that the host kernel
|
|
was not compiled using a GCC-3.0 (or later) compiler, one will need to
|
|
be compiled. The host system will then need to be rebooted to use the
|
|
newly compiled kernel. Instructions for compiling the kernel and
|
|
configuring the boot loader (assuming the host uses GRUB) are located
|
|
in <xref linkend="chapter-bootable"/>.</para>
