4 | <title>Glibc installation</title>
|
---|
5 |
|
---|
6 | <para>The Glibc build system is very well self-contained and will install
|
---|
7 | perfectly, even though our compiler specs file and linker are still pointing
|
---|
8 | at <filename>/tools</filename>. We cannot adjust the specs and linker before
|
---|
9 | the Glibc install, because the Glibc autoconf tests would then give bogus
|
---|
10 | results 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 <emphasis>
|
---|
13 | critical</emphasis>. Our advice is to not skip it under any
|
---|
14 | circumstances.</para></note>
|
---|
15 |
|
---|
16 | <para>Before starting to build Glibc, remember to unpack the Glibc-linuxthreads
|
---|
17 | again inside the <filename>glibc-&glibc-version;</filename> directory, and to
|
---|
18 | unset any environment variables that override the default optimization
|
---|
19 | flags.</para>
|
---|
20 |
|
---|
21 | <para>Then apply the same patch we used previously:</para>
|
---|
22 |
|
---|
23 | <para><screen><userinput>patch -Np1 -i ../glibc-2.3.2-sscanf-1.patch
|
---|
24 | </userinput></screen></para>
|
---|
25 |
|
---|
26 | <para>The Glibc documentation recommends building Glibc outside of the source
|
---|
27 | directory in a dedicated build directory:</para>
|
---|
28 |
|
---|
29 | <para><screen><userinput>mkdir ../glibc-build
|
---|
30 | cd ../glibc-build</userinput></screen></para>
|
---|
31 |
|
---|
32 | <para>Now prepare Glibc for compilation:</para>
|
---|
33 |
|
---|
34 | <para><screen><userinput>../glibc-&glibc-version;/configure --prefix=/usr \
|
---|
35 | --disable-profile --enable-add-ons \
|
---|
36 | --libexecdir=/usr/bin --with-headers=/usr/include</userinput></screen></para>
|
---|
37 |
|
---|
38 | <para>The meaning of the new configure options:</para>
|
---|
39 |
|
---|
40 | <itemizedlist>
|
---|
41 | <listitem><para><userinput>--libexecdir=/usr/bin</userinput>: This will
|
---|
42 | cause the <filename>pt_chown</filename> program to be installed in the
|
---|
43 | <filename>/usr/bin</filename> directory.</para></listitem>
|
---|
44 |
|
---|
45 | <listitem><para><userinput>--with-headers=/usr/include</userinput>: This
|
---|
46 | ensures that the kernel headers in <filename>/usr/include</filename> are used
|
---|
47 | for this build. If you don't pass this switch then the headers from
|
---|
48 | <filename>/tools/include</filename> are used which of course is not ideal
|
---|
49 | (although they should be identical). Using this switch has the advantage
|
---|
50 | that you will be informed immediately should you have forgotten to install the
|
---|
51 | kernel headers into <filename>/usr/include</filename>.</para></listitem>
|
---|
52 | </itemizedlist>
|
---|
53 |
|
---|
54 | <para>Compile the package:</para>
|
---|
55 |
|
---|
56 | <para><screen><userinput>make</userinput></screen></para>
|
---|
57 |
|
---|
58 | <para>Test the results:</para>
|
---|
59 |
|
---|
60 | <para><screen><userinput>make check</userinput></screen></para>
|
---|
61 |
|
---|
62 | <para>And install the package:</para>
|
---|
63 |
|
---|
64 | <para><screen><userinput>make install</userinput></screen></para>
|
---|
65 |
|
---|
66 | <para>The locales that can make your system respond in a different language
|
---|
67 | weren't installed by the above command. Do it with this:</para>
|
---|
68 |
|
---|
69 | <para><screen><userinput>make localedata/install-locales</userinput></screen></para>
|
---|
70 |
|
---|
71 | <para>An alternative to running the previous command is to install only those
|
---|
72 | locales which you need or want. This can be achieved using the
|
---|
73 | <userinput>localedef</userinput> command. Information on this can be found in
|
---|
74 | the <filename>INSTALL</filename> file in the
|
---|
75 | <filename>glibc-&glibc-version;</filename> tree. However, there are a number
|
---|
76 | of locales that are essential for the tests of future packages to pass
|
---|
77 | correctly. The following instructions, in place of the install-locales
|
---|
78 | command above, will install the minimum set of locales necessary for the
|
---|
79 | tests to run successfully:</para>
|
---|
80 |
|
---|
81 | <para><screen><userinput>mkdir -p /usr/lib/locale
|
---|
82 | localedef -i de_DE -f ISO-8859-1 de_DE

83 | localedef -i de_DE@euro -f ISO-8859-15 de_DE@euro

84 | localedef -i en_HK -f ISO-8859-1 en_HK

85 | localedef -i en_PH -f ISO-8859-1 en_PH

86 | localedef -i en_US -f ISO-8859-1 en_US

91 | localedef -i ja_JP -f EUC-JP ja_JP</userinput></screen></para>
|
---|
92 |
|
---|
93 | <para>Finally, build the linuxthreads man pages:</para>
|

94 |

95 | <para><screen><userinput>make -C ../glibc-2.3.2/linuxthreads/man</userinput></screen></para>
|
---|
96 |
|

97 | <para>And install these pages:</para>
