[fd8b059] | 86 |

| 87 | <para>The reason for the kernel version requirement is that thread-local
|
---|
| 88 | storage support in Binutils will not be built and the Native POSIX
|
---|
| 89 | Threading Library (NPTL) test suite will segfault if the host's kernel

| 90 | isn't at least a 2.6.x version compiled with a 3.0 or later release of
|
---|
| 91 | GCC.</para>
|
---|
| 92 |
|
---|
[a12d507] | 93 | <para>If the host kernel is either earlier than 2.6.x, or it was not
|
---|
| 94 | compiled using a GCC-3.0 (or later) compiler, you will have to replace
|
---|
| 95 | the kernel with one adhering to the specifications. There are two methods
|
---|
| 96 | you can take to solve this. First, see if your Linux vendor provides a
|
---|
| 97 | 2.6 kernel package. If so, you may wish to install it. If your vendor
|
---|
| 98 | doesn't offer a 2.6 kernel package, or you would prefer not to install it,
|
---|
| 99 | then you can compile a 2.6 kernel yourself. Instructions for compiling the
|
---|
| 100 | kernel and configuring the boot loader (assuming the host uses GRUB) are
|
---|
| 101 | located in <xref linkend="chapter-bootable"/>.</para>
