<title>Installation of Linux-Libc-Headers</title>

<para>For years it has been common practice to use so-called <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 such
things should not be done.  Thus was born the linux-libc-headers project,
designed to maintain an API stable version of the Linux headers.</para>

<para>Install the header files:</para>

<screen><userinput>cp -R include/asm-i386 /usr/include/asm
cp -R include/linux /usr/include</userinput></screen>

<para>Assure that all the headers are owned by root:</para>

<screen><userinput>chown -R root:root /usr/include/{asm,linux}</userinput></screen>

<para>And make sure all the users can read the headers:</para>

<screen><userinput>find /usr/include/{asm,linux} -type d -exec chmod 755 {} \;
find /usr/include/{asm,linux} -type f -exec chmod 644 {} \;</userinput></screen>
