30 | <para>This package is known to behave badly when you change its default
|
---|
31 | optimization flags (including the <parameter>-march</parameter> and
|
---|
32 | <parameter>-mcpu</parameter> options). Therefore, if you have defined any
|
---|
33 | environment variables that override default optimizations, such as CFLAGS and
|
---|
34 | CXXFLAGS, we recommend un-setting them when building Glibc.</para>

|

117 |
|
---|
118 | <para>The missing or incompatible <command>msgfmt</command> program is
|

119 | generally harmless, but it's believed it can sometimes cause problems when

120 | running the test suite.</para>
|

121 |
|

122 | <para>Compile the package:</para>

123 |

124 | <screen><userinput>make</userinput></screen>
|
---|
125 |
|
---|
126 | <para>Compilation is now complete. As mentioned earlier, running the test suites
|
---|
127 | for the temporary tools installed in this chapter is not mandatory. If you want
|
---|
128 | to run the Glibc test suite though, the following command will do so:</para>
|
---|
129 |
|
---|
130 | <screen><userinput>make check</userinput></screen>
|
---|
131 |
|
---|
132 | <para>For a discussion of test failures that are of particular
|
---|
133 | importance, please see <xref linkend="ch-system-glibc"/>.</para>
|
---|
134 |
|
---|
135 | <para>In this chapter, some tests can be adversely affected by existing tools or
|
---|
136 | environmental issues on the host system. In short, don't worry too much if you
|
---|
137 | see Glibc test suite failures in this chapter. The Glibc in
|
---|
138 | <xref linkend="chapter-building-system"/> is the one we'll ultimately end up
|
---|
139 | using, so that is the one we would really like to see pass the tests (but even
|
---|
140 | there some failures could still occur -- the <emphasis>math</emphasis> tests,
|
---|
141 | for example).</para>
|
---|
142 |
|
---|
143 | <para>When experiencing a failure, make a note of it, then continue by reissuing
|
---|
144 | the <command>make check</command>. The test suite should pick up where it left
|
---|
145 | off and continue. You can circumvent this stop-start sequence by issuing a
|
---|
146 | <command>make -k check</command>. If you do that though, be sure to log the
|
---|
147 | output so that you can later peruse the log file and examine the total number of
|
---|
148 | failures.</para>
|
---|
149 |
|
---|
150 | <para>Though it is a harmless message, the install stage of Glibc will at the
|
---|
151 | end complain about the absence of <filename>/tools/etc/ld.so.conf</filename>.
|
---|
152 | Prevent this confusing little warning with:</para>
|
---|
153 |
|
---|
154 | <screen><userinput>mkdir /tools/etc
|
---|
155 | touch /tools/etc/ld.so.conf</userinput></screen>
|
---|
156 |
|
---|
157 | <para>Now install the package:</para>
|
---|
158 |
|
---|
159 | <screen><userinput>make install</userinput></screen>
|
---|
160 |
|
---|
161 | <para>Different countries and cultures have varying conventions for how to
|
---|
162 | communicate. These conventions range from very simple ones, such as the format
|
---|
163 | for representing dates and times, to very complex ones, such as the language
|
---|
164 | spoken. The <quote>internationalization</quote> of GNU programs works by means
|
---|
165 | of <emphasis>locales</emphasis>.</para>
|
---|
166 |
|
---|
167 | <note><para>If you are not running the test suites here in this chapter as per
|
---|
168 | our recommendation, there is little point in installing the locales now. We'll
|
---|
169 | be installing the locales in the next chapter.</para></note>
|
---|
170 |
|
---|
171 | <para>If you still want to install the Glibc locales anyway, the following
|
---|
172 | command will do so:</para>
|
---|
173 |
|
---|
174 | <screen><userinput>make localedata/install-locales</userinput></screen>
|
---|
175 |
|
---|
176 | <para>An alternative to running the previous command is to install only those
|
---|
177 | locales which you need or want. This can be achieved by using the
|
---|
178 | <command>localedef</command> command. Information on this can be found in
|
---|
179 | the <filename>INSTALL</filename> file in the Glibc source. However, there are
|
---|
180 | a number of locales that are essential for the tests of future packages to
|
---|
181 | pass, in particular, the <emphasis>libstdc++</emphasis> tests from GCC. The
|
---|
182 | following instructions, instead of the install-locales target above, will
|
---|
183 | install the minimum set of locales necessary for the tests to run
|
---|
184 | successfully:</para>
