14 | versions indicated. This should not be an issue for most modern Linux

73 | <para>There are two main reasons for the kernel version requirement. First,
|
---|
74 | the Native POSIX Threading Library (NPTL) test suite will segfault if the
|
---|
75 | host's kernel has not been compiled with GCC-3.0 or a later version. Second,
|
---|
76 | the 2.6.2 or later version of the kernel is required for the use of Udev.
|
---|
77 | Udev creates devices dynamically by reading from the <systemitem
|
---|
78 | class="filesystem">sysfs</systemitem> file system. However, support for this
|
---|
79 | filesystem has only recently been implemented in most of the kernel drivers.
|
---|
80 | We must be sure that all critical system devices get created properly.</para>
|
---|
81 |
|
---|
82 | <para>In order to determine whether the host kernel meets the requirements
|
---|
83 | outlined above, run the following command:</para>
|
---|
84 |
|
---|
85 | <screen role="nodump"><userinput>cat /proc/version</userinput></screen>
|
---|
86 |
|
---|
87 | <para>This will produce output similar to:</para>
|
---|
88 |
|
---|
89 | <screen><computeroutput>Linux version 2.6.2 (user@host) (gcc version 3.4.0) #1
|
---|
90 | Tue Apr 20 21:22:18 GMT 2004</computeroutput></screen>
|
---|
91 |
|
---|
92 | <para>If the results of the above command do not state that the host kernel
|
---|
93 | is either 2.6.2 (or later), or that it was not compiled using a GCC-3.0 (or
|
---|
94 | later) compiler, one will need to be installed. There are two methods you
|
---|
95 | can take to solve this. First, see if your Linux vendor provides a 2.6.2 (or
|
---|
96 | later) kernel package. If so, you may wish to install it. If your vendor
|
---|
97 | doesn't offer a 2.6.2 (or later) kernel package, or you would prefer not to
|
---|
98 | install it, then you can compile a 2.6 kernel yourself. Instructions for
|
---|
99 | compiling the kernel and configuring the boot loader (assuming the host
|
---|
100 | uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>
