6.21.1. 安装 Attr
|
||
</h2>
|
||
<p>
|
||
修改文件目录，使它成为版本目录：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class=
|
||
"command">sed -i -e 's|/@pkg_name@|&-@pkg_version@|' include/builddefs.in</kbd>
|
||
</pre>
|
||
<p>
|
||
防止再次安装已经由 Man-pages 软件包安装了的帮助手册：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">sed -i -e "/SUBDIRS/s|man2||" man/Makefile</kbd>
|
||
</pre>
|
||
<p>
|
||
准备编译 Attr：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">./configure --prefix=/usr</kbd>
|
||
</pre>
|
||
<p>
|
||
编译软件包：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make</kbd>
|
||
</pre>
|
||
<p>
|
||
测试需要在支持扩展属性的文件系统上运行，例如 ext2、ext3、或者 ext4。
|
||
如果同时运行多个测试会导致测试失败(-j 选项大于 1)。输入命令检查结果：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make -j1 tests root-tests</kbd>
|
||
</pre>
|
||
<p>
|
||
安装软件包：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make install install-dev install-lib
|
||
chmod -v 755 /usr/lib/libattr.so</kbd>
|
||
</pre>
|
||
<p>
|
||
需要移动共享库到<code class=
|
||
"filename">/lib</code>，因此需要重建 <code class=
|
||
"filename">/usr/lib</code> 中的 <code class=
|
||
"filename">.so</code> 文件：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">mv -v /usr/lib/libattr.so.* /lib
|
||
ln -sfv ../../lib/$(readlink /usr/lib/libattr.so) /usr/lib/libattr.so</kbd>
