[81fd230] | 10 | <para>The host must be running at least a 2.6.2 kernel compiled with
|
---|
| 11 | GCC-3.0 or higher. There are two main reasons for this high
|
---|
| 12 | requirement. First, the Native POSIX Threading Library (NPTL)
|
---|
| 13 | test suite will segfault if the host's kernel has not been compiled with
|
---|
| 14 | GCC-3.0 or a later version. Secondly, the 2.6.2 or later version of
|
---|
| 15 | the kernel is required for the use of Udev. Udev creates devices
|
---|
| 16 | dynamically by reading from the <systemitem
|
---|
| 17 | class="filesystem">sysfs</systemitem> file system. However, support
|
---|
| 18 | for this filesystem has only recently been implemented in most of
|
---|
| 19 | the kernel drivers. We must be sure that all critical system devices
|
---|
| 20 | get created properly.</para>
|
---|
| 21 |
|
---|
| 22 | <para>In order to determine whether the host kernel meets the
|
---|
| 23 | requirements outlined above, run the following command:</para>
|
---|
| 24 |
|
---|
| 25 | <screen><userinput>cat /proc/version</userinput></screen>
|
---|
| 26 |
|
---|
| 27 | <para>This will produce output similar to:</para>
|
---|

|
---|
| 29 | <screen><computeroutput>Linux version 2.6.2 (user@host) (gcc version 3.4.0) #1

|
---|
| 31 |
|
---|
| 32 | <para>If the results of the above command state that the host kernel
|
---|
| 33 | was not compiled using a GCC-3.0 (or later) compiler, one will need to
|
---|
| 34 | be compiled. The host system will then need to be rebooted to use the
|
---|
| 35 | newly compiled kernel. Instructions for compiling the kernel and
|
---|
| 36 | configuring the boot loader (assuming the host uses GRUB) are located
|
---|
| 37 | in <xref linkend="chapter-bootable"/>.</para>
