6.7.1. Installation of Linux API 头文件

<p>
|
||
Linux 内核需要提供一个应用编程接口（API）供系统的 C 库（LFS 中的 Glibc）调用。这是通过
|
||
This is done by way of sanitizing various C header files that are
|
||
shipped in the Linux kernel source tarball.
|
||
</p>
|
||
<p>
|
||
为了确保在之前的动作里没有留下旧文件和依赖关系：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make mrproper</kbd>
|
||
</pre>
|
||
<p>
|
||
现在要从源代码里解出用户可见内核头文件。因为解压过程会删除目标目录下所有文件，所以会先输出到一个本地中间目录后再拷贝到需要的地方。而且里面还有一些隐藏文件是给内核开发人员用的，而 LFS 不需要，所以会将它们从中间目录里删除。

find dest/include \( -name .install -o -name ..install.cmd \) -delete
