38 | <para>Prepare Zlib for compilation:</para>
|

40 | <screen><userinput>./configure --prefix=/usr --shared</userinput></screen>
|

45 |
|

46 | <para>To test the results, issue:

47 | <userinput>make check</userinput>.</para>

49 | <para>Install the shared library:</para>

50 |

51 | <screen><userinput>make install</userinput></screen>
|
---|
52 |
|
---|
53 | <para>Now also build the non-shared (static) library:</para>
|
---|
54 |
|
---|
55 | <screen><userinput>make clean
|
---|
56 | ./configure --prefix=/usr
|
---|
57 | make</userinput></screen>
|
---|
58 |
|
---|
59 | <para>To again test the results, issue:
|
---|
60 | <userinput>make check</userinput>.</para>
|
---|
61 |
|
---|
62 | <para>Install the static library:</para>
|
---|
63 |
|
---|
64 | <screen><userinput>make install</userinput></screen>
|
---|
65 |
|
---|
66 | <para>And fix the permissions on the static library:</para>
|
---|
67 |
|
---|
68 | <screen><userinput>chmod 644 /usr/lib/libz.a</userinput></screen>
|
---|
69 |
|
---|
70 | <para>It is good policy and common practice to place important libraries into
|
---|
71 | the <filename class="directory">/lib</filename> directory. This matters most
|
---|
72 | in scenarios where <filename class="directory">/usr</filename> is on a
|
---|
73 | separate partition. Essentially, the run-time components of any libraries that
|
---|
74 | are used by programs in <filename class="directory">/bin</filename> or
|
---|
75 | <filename class="directory">/sbin</filename> should reside in
|
---|
76 | <filename class="directory">/lib</filename> so that they are on the root
|
---|
77 | partition and available in the event of
|
---|
78 | <filename class="directory">/usr</filename> being inaccessible.</para>
|
---|
79 |
|
---|
80 | <para>For the above reason we move the run-time components of the shared Zlib
|
---|
81 | into <filename class="directory">/lib</filename>:</para>
|
---|
82 |
|
---|
83 | <screen><userinput>mv /usr/lib/libz.so.* /lib</userinput></screen>
|
---|
84 |
|
---|
85 | <para>Now we need to fix the <filename class="symlink">/usr/lib/libz.so</filename> symlink
|
---|
86 | because we just moved the file it points to:</para>
|
---|
87 |
|
---|
88 | <screen><userinput>ln -sf ../../lib/libz.so.1 /usr/lib/libz.so</userinput></screen>
