  3. <title>Glibc installation</title>
  4. <para>Before starting to install Glibc, you must <userinput>cd</userinput>
  5. into the <filename>glibc-&glibc-version;</filename> directory and unpack
  6. Glibc-linuxthreads in that directory, not in <filename>/usr/src</filename> as
  7. you would normally do.</para>
  8. <para>This package is known to behave badly when you have changed its
  9. default optimization flags (including the -march and -mcpu options).
  10. Therefore, if you have defined any environment variables that override
  11. default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
  12. them when building Glibc.</para>
  13. <para>Basically, compiling Glibc in any other way than the book suggests
  14. is putting your system at a very high risk.</para>
  15. <para>Though it is a harmless message, the install stage of Glibc will
  16. complain about the presence of /etc/ld.so.conf (or lack thereof). Fix
  17. this annoying little error:</para>
  18. <para><screen><userinput>mkdir /stage1/etc
  19. touch /stage1/etc/ld.so.conf</userinput></screen></para>
  20. <para>The documentation that comes with Glibc recommends to build the package
  21. not in the source directory but in a separate, dedicated directory:</para>
  22. <para><screen><userinput>mkdir ../glibc-build
  23. cd ../glibc-build</userinput></screen></para>
  24. <para>Next, prepare Glibc to be compiled:</para>
  25. <para><screen><userinput>../glibc-&glibc-version;/configure --prefix=/stage1 \
  26. &nbsp;&nbsp;&nbsp;&nbsp;--disable-profile --enable-add-ons \
  27. &nbsp;&nbsp;&nbsp;&nbsp;--with-headers=/stage1/include \
  28. &nbsp;&nbsp;&nbsp;&nbsp;--with-binutils=/stage1/bin \
  29. &nbsp;&nbsp;&nbsp;&nbsp;--without-gd</userinput></screen></para>
  30. <para>The meaning of the configure options are:</para>
  31. <itemizedlist>
  32. <listitem><para><userinput>--disable-profile</userinput>: This disables the
  33. building of the libraries with profiling information. Omit this option if you
  34. plan to do profiling.</para></listitem>
  35. <listitem><para><userinput>--enable-add-ons</userinput>: This enables any
  36. add-ons that we installed with Glibc, in our case Linuxthreads.</para></listitem>
  37. <listitem><para><userinput>--libexecdir=/usr/bin</userinput>: This will
  38. cause the <filename>pt_chown</filename> program to be installed in the
  39. <filename>/usr/bin</filename> directory.</para></listitem>
  40. </itemizedlist>
  41. <para>During this stage you will see the following warning:</para>
  42. <blockquote><screen>configure: warning:
  43. *** These auxiliary programs are missing or too old: msgfmt
  44. *** some features will be disabled.
  45. *** Check the INSTALL file for required versions.</screen></blockquote>
  46. <para>The missing <filename>msgfmt</filename> program (from the Gettext
  47. package, which we'll install later) won't cause any problems. The
  48. <filename>msgfmt</filename> is used to generate the binary translation
  49. files that can make your system talk in a different language. Because these
  50. translation files have already been generated for you, there is no need for
  51. <filename>msgfmt</filename>. You'd only need the program if you change the
  52. translation source files (the <filename>*.po</filename> files in the
  53. <filename class="directory">po</filename> subdirectory), which
  54. would require you to regenerate the binary files.</para>
  55. <para>Continue with compiling the package:</para>
  56. <para><screen><userinput>make
  57. make check
  58. make install</userinput></screen></para>
  59. <para>The locales (used by Glibc to make your Linux system talk in a different
  60. language) weren't installed when you ran the previous command, so we have to
  61. do that ourselves now:</para>
  62. <para><screen><userinput>make localedata/install-locales</userinput></screen></para>
  63. <para>An alternative to running the previous command is to install only those
  64. locales which you need or want. This can be achieved using the localedef
  65. command. Information on this can be found in the <filename>INSTALL</filename>
  66. file in the <filename>glibc-&glibc-version;</filename> tree.</para>
