Message:

Updated to Glibc 2.6. This includes adding a sed to Coreutils and Gzip to rename their internal implementations of futimens which are incompatible with the implementation provided by Glibc. Added a target tripplet based optimization to glibc on x86 and 32bit build on x86_64 so that glibc will build properly now that i386 is no longer supported. Also added a note to the build variables page the i386-pc-linux-gnu is not supported by glibc.

    143     <para>To save time, an alternative to running the previous command (which
    144     generates and installs every locale listed in the
    145     glibc-&glibc-version;/localedata/SUPPORTED file) is to install only
    146     those locales that are wanted and needed. This can be achieved by using
    147     the <command>localedef</command> command. Information on this command is
    148     located in the <filename>INSTALL</filename> file in the Glibc source.
    149     However, there are a number of locales that are essential in order for the
    150     tests of future packages to pass, in particular, the
    151     <emphasis>libstdc++</emphasis> tests from GCC. The following instructions,
    152     instead of the <parameter>install-locales</parameter> target used above,
    153     will install the minimum set of locales necessary for the tests to run
    154     successfully:</para>

    169     <para>Some locales installed by the <command>make
    170     localedata/install-locales</command> command above are not properly
    171     supported by some applications that are in the CLFS and BLFS books. Because
    172     of the various problems that arise due to application programmers making
    173     assumptions that break in such locales, CLFS should not be used in locales
    174     that utilize multibyte character sets (including UTF-8) or right-to-left
    175     writing order.  Numerous unofficial and unstable patches are required to
    176     fix these problems, and it has been decided by the CLFS developers not to
    177     support such complex locales at this time. This applies to the ja_JP and
    178     fa_IR locales as well&mdash;they have been installed only for GCC and
    179     Gettext tests to pass, and the <command>watch</command> program (part of
    180     the Procps package) does not work properly in them. Various attempts to
    181     circumvent these restrictions are documented in internationalization-related
    182     hints.</para>
