|

[fd8b059] | 84 |
|

[9ee226e] | 85 | <para>The reason for the kernel version requirement is that we specify
|
---|
| 86 | that version when building <application>glibc</application> in Chapter 6
|
---|
| 87 | at the recommendation of the developers. This can be overridden if
|
---|
| 88 | desired but at least a 2.6.0 kerenl is required because thread-local
|
---|
[fd8b059] | 89 | storage support in Binutils will not be built and the Native POSIX
|
---|
| 90 | Threading Library (NPTL) test suite will segfault if the host's kernel
|
---|
| 91 | isn't at least a 2.6.x version compiled with a 3.0 or later release of
|
---|
| 92 | GCC.</para>
|
---|
| 93 |
|
---|
[9ee226e] | 94 | <para>If the host kernel is either earlier than 2.6.18, or it was not
|
---|
| 95 | compiled using a GCC-3.0 (or later) compiler, you will need to replace
|
---|
| 96 | the kernel with one adhering to the specifications. There are two ways
|
---|
| 97 | you can go about this. First, see if your Linux vendor provides a 2.6.18
|
---|
| 98 | or later kernel package. If so, you may wish to install it. If your
|
---|
| 99 | vendor doesn't offer an acceptable kernel package, or you would prefer not to
|
---|
| 100 | install it, you can compile a kernel yourself. Instructions for
|
---|
| 101 | compiling the kernel and configuring the boot loader (assuming the host
|
---|
| 102 | uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>

| 104 | <note>
|

| 105 | <para>This version of the book builds a 32-bit Linux system and
|
---|
| 106 | requires an existing 32-bit version of of the kernel on the Intel/AMD
|
---|
| 107 | x86 architecture. Adding capabilty for x86_64 systems is a major
|
---|
| 108 | objective of a future version of LFS. Support for 64-bit systems and
|
---|
| 109 | additional architectures can be found in the Cross-Compiled Linux From
|

| 110 | Scratch (CLFS) project at <ulink url="http://cross-lfs.org/view/svn/"/>.
