<title>Host System Requirements</title>
<para>Your host system should have the following software with the
minimum versions indicated. This should not be an issue for most
modern Linux distributions. Also note that many distributions will
place software headers into separate packages, often in the form of
<quote><package-name>-devel</quote> or
<quote><package-name>-dev</quote>. Be sure to install those if
your distribution provides them. For each package a command has been
added to help you to determine what version is installed on your
host.</para>

<para><emphasis role="strong">Linux Kernel-2.6.x</emphasis>
(having been compiled with Gcc-3.0)</para>
<para>The reason for the kernel version requirement is that thread-local
storage support in Binutils will not be built and the Native POSIX
Threading Library (NPTL) test suite will segfault if the host's kernel
isn't at least a 2.6.x version compiled with a 3.0 or later release of
GCC.</para>
<para>In order to determine whether the host kernel meets the requirements
outlined above, run the following command:</para>
<screen role="nodump"><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 do not state that the host
kernel is either 2.6.x, or that it was not compiled using a GCC-3.0
(or later) compiler, you will have to replace the kernel with one
adhering to the specifications. There are two methods you can take
to solve this. First, see if your Linux vendor provides a 2.6 kernel
package. If so, you may wish to install it. If your vendor doesn't
offer a 2.6 kernel package, or you would prefer not to install it,
then you can compile a 2.6 kernel yourself. Instructions for compiling
the kernel and configuring the boot loader (assuming the host uses GRUB)
are located in <xref linkend="chapter-bootable"/>.</para>
