6.7.1. Installation of Linux API Headers
|
|
</h2>
|
|
<p>
|
|
The Linux kernel needs to expose an Application Programming
|
|
Interface (API) for the system's C library (Glibc in LFS) to use.
|
|
This is done by way of sanitizing various C header files that are
|
|
shipped in the Linux kernel source tarball.
|
|
</p>
|
|
<p>
|
|
Make sure there are no stale files and dependencies lying around
|
|
from previous activity:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make mrproper</kbd>
|
|
</pre>
|
|
<p>
|
|
Now extract the user-visible kernel headers from the source. They
|
|
are placed in an intermediate local directory and copied to the
|
|
needed location because the extraction process removes any existing
|
|
files in the target directory. There are also some hidden files
|
|
used by the kernel developers and not needed by LFS that are
|
|
removed from the intermediate directory.
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make INSTALL_HDR_PATH=dest headers_install
|
|
find dest/include \( -name .install -o -name ..install.cmd \) -delete
|
|
</kbd><kbd class="command">cp -rv dest/include/* /usr/include</kbd>
