| 4 | <para>Before starting to install glibc, you must cd into the
|
|---|
| 5 | glibc-&glibc-version; directory and unpack glibc-linuxthreads inside
|
|---|
| 6 | the glibc-&glibc-version; directory, not in /usr/src as you normally
|
|---|
| 7 | would do.</para>

|

| 9 | <para>This package is known to behave badly when you have changed its
|
|---|
| 10 | default optimization flags (including the -march and -mcpu options). Glibc
|
|---|
| 11 | is best left alone. Therefore, if you have defined any environment variables
|
|---|
| 12 | that override default optimizations, such as CFLAGS and CXXFLAGS, we
|
|---|
| 13 | recommend unsetting or modifying them when building binutils. You have
|
|---|
| 14 | been warned.</para>
|
|---|
| 15 |
|
|---|
| 16 | <para>Also, don't pass the --enable-kernel option to the configure
|
|---|
| 17 | script. It's known to cause segmentation faults when other packages like
|
|---|
| 18 | fileutils, make and tar are linked against it.</para>
|
|---|
| 19 |
|
|---|
| 20 | <para>Basically, compiling Glibc in any other way than the book suggests
|
|---|
| 21 | is putting your system at very high risk.</para>

| 23 | <para>Install Glibc by running the following commands:</para>

|

|

| 41 | <para>An alternative to running <userinput>make
|
|---|
| 42 | localedata/install-locales</userinput> is to only install those locales
|
|---|
| 43 | which you need or want. This can be achieved using the localedef
|
|---|
| 44 | command. Information on this can be found in the INSTALL
|
|---|
| 45 | file in the glibc-&glibc-version; tree.</para>
|

| 46 |
|
|---|
| 47 | <para>During the configure stage you will see the following warning:</para>
|
|---|
| 48 |
|
|---|
| 49 | <blockquote><screen>configure: warning:
|
|---|
| 50 | *** These auxiliary programs are missing or too old: msgfmt
|
|---|
| 51 | *** some features will be disabled.
|
|---|
| 52 | *** Check the INSTALL file for required versions.</screen></blockquote>
|
|---|
| 53 |
|
|---|
| 54 | <para>The missing msgfmt (from the gettext package which we will install
|
|---|
| 55 | later in this chapter) won't cause any problems. msgfmt is used to generate
|
|---|
| 56 | the binary translation files that are used to make your system talk in a
|
|---|
| 57 | different language. Because these translation files have already been
|
|---|
| 58 | generated for you, there is no need for msgfmt. You'd only need msgfmt if
|
|---|
| 59 | you change the translation source files (the <filename>*.po</filename>
|
|---|
| 60 | files in the <filename class="directory">po</filename> subdirectory) which\
|
|---|
| 61 | would require you to re-generate the binary files.</para>
