<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.</para>

<para><emphasis role="strong">Linux Kernel-2.6.x</emphasis>
|
|
(having been compiled with GCC-3.0 or greater)</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>If the host kernel is either earlier than 2.6.x, or 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>
|
|
|
|
<note>
|
|
<para>This version of the book builds a 32-bit Linux system and
|
|
requires an existing 32-bit version of of the kernel on the Intel/AMD
|
|
x86 architecture. Adding capabilty for x86_64 systems is a major
|
|
objective of a future version of LFS. Support for 64-bit systems and
|
|
additional architectures can be found in the Cross-Compiled Linux From
|
|
Scratch (CLFS) project at <ulink url="http://cross-lfs.org/view/svn/"/>.

point to other software (such as dash, mawk, etc.) may work, but are not

deviation from the instructions or additional patches to some
