<title>Installation of Linux-Libc-Headers</title>
<para>For years it has been common practice to use <quote>raw</quote>
kernel headers (straight from a kernel tarball) in <filename
class="directory">/usr/include</filename>, but over the last few
years, the kernel developers have taken a strong stance that this
should not be done. This gave birth to the Linux-Libc-Headers Project,
which was designed to maintain an API stable version of the Linux
headers.</para>
<para>Install the header files:</para>
<screen><userinput>install -dv /usr/include/asm
cp -Rv include/asm-i386/* /usr/include/asm
cp -Rv include/linux /usr/include</userinput></screen>
<para>Ensure that all the headers are owned by root:</para>
<screen><userinput>chown -Rv root:root /usr/include/{asm,linux}</userinput></screen>
<para>Make sure the users can read the headers:</para>
<screen><userinput>find /usr/include/{asm,linux} -type d -exec chmod -v 755 {} \;
find /usr/include/{asm,linux} -type f -exec chmod -v 644 {} \;</userinput></screen>
