Internal markup reworking to fix the extraneous whitespace problem in the "tidy generated" web site pages. Essentially replace all ocurrences of <para><screen> with <screen> (and of course the matching closing tags).

4<title>Glibc installation</title>
5
6<para>The Glibc build system is very well self-contained and will install
7perfectly, even though our compiler specs file and linker are still pointing
8at <filename>/tools</filename>. We cannot adjust the specs and linker before
9the Glibc install, because the Glibc autoconf tests would then give bogus
10results and thus defeat our goal of achieving a clean build.</para>
11
12<note><para>The test suite for Glibc in this section is considered
13<emphasis>critical</emphasis>. Our advice is to not skip it under any
14circumstance.</para></note>
15
16<para>Before starting to build Glibc, remember to unpack the Glibc-linuxthreads
17again inside the <filename>glibc-&glibc-version;</filename> directory, and to
18unset any environment variables that override the default optimization
19flags.</para>
20
21<para>Then apply the same patch we used previously:</para>
22
23<screen><userinput>patch -Np1 -i ../&glibc-sscanf-patch;</userinput></screen>
24
25<para>The Glibc documentation recommends building Glibc outside of the source
26directory in a dedicated build directory:</para>
27
28<screen><userinput>mkdir ../glibc-build
29cd ../glibc-build</userinput></screen>
30
31<para>Now prepare Glibc for compilation:</para>
32
33<screen><userinput>../glibc-&glibc-version;/configure --prefix=/usr \
34&nbsp;&nbsp;&nbsp;&nbsp;--disable-profile --enable-add-ons \
35&nbsp;&nbsp;&nbsp;&nbsp;--libexecdir=/usr/bin --with-headers=/usr/include</userinput></screen>
36
37<para>The meaning of the new configure options:</para>
38
39<itemizedlist>
40<listitem><para><userinput>--libexecdir=/usr/bin</userinput>: This will
41cause the <filename>pt_chown</filename> program to be installed in the
42<filename>/usr/bin</filename> directory.</para></listitem>
43
44<listitem><para><userinput>--with-headers=/usr/include</userinput>: This
45ensures that the kernel headers in <filename>/usr/include</filename> are used
46for this build. If you don't pass this switch then the headers from
47<filename>/tools/include</filename> are used which of course is not ideal
48(although they should be identical). Using this switch has the advantage
49that you will be informed immediately should you have forgotten to install the
50kernel headers into <filename>/usr/include</filename>.</para></listitem>
51</itemizedlist>
52
53<para>Compile the package:</para>
54
55<screen><userinput>make</userinput></screen>
56
57<para>Test the results:</para>
58
59<screen><userinput>make check</userinput></screen>
60
61<para>The test suite notes from <xref linkend="ch05-glibc"/> are still very much
62appropriate here. Be sure to refer back there should you have any doubts.</para>
63
64<para>And install the package:</para>
65
66<screen><userinput>make install</userinput></screen>
67
68<para>The locales that can make your system respond in a different language
69weren't installed by the above command. Do it with this:</para>
70
71<screen><userinput>make localedata/install-locales</userinput></screen>
72
73<para>An alternative to running the previous command is to install only those
74locales which you need or want. This can be achieved using the
75<userinput>localedef</userinput> command. Information on this can be found in
76the <filename>INSTALL</filename> file in the
77<filename>glibc-&glibc-version;</filename> tree. However, there are a number
78of locales that are essential for the tests of future packages to pass
79correctly. The following instructions, in place of the install-locales
80command above, will install the minimum set of locales necessary for the
81tests to run successfully:</para>
82
83<screen><userinput>mkdir -p /usr/lib/locale
84localedef -i de_DE -f ISO-8859-1 de_DE
85localedef -i de_DE@euro -f ISO-8859-15 de_DE@euro
86localedef -i en_HK -f ISO-8859-1 en_HK
87localedef -i en_PH -f ISO-8859-1 en_PH
88localedef -i en_US -f ISO-8859-1 en_US
89localedef -i es_MX -f ISO-8859-1 es_MX
90localedef -i fr_FR -f ISO-8859-1 fr_FR
91localedef -i fr_FR@euro -f ISO-8859-15 fr_FR@euro
92localedef -i it_IT -f ISO-8859-1 it_IT
93localedef -i ja_JP -f EUC-JP ja_JP</userinput></screen>
94
95<para>Finally, build the linuxthreads man pages:</para>
96
97<screen><userinput>make -C ../&glibc-dir;/linuxthreads/man</userinput></screen>
98
99<para>And install these pages:</para>
100
101<screen><userinput>make -C ../&glibc-dir;/linuxthreads/man install</userinput></screen>
