<title>Installation of Glibc</title>
|
|
|
|
<para>Before starting to install glibc, you must cd into the
|
|
glibc-&glibc-version; directory and unpack glibc-linuxthreads inside
|
|
the glibc-&glibc-version; directory, not in /usr/src as you normally
|
|
would do.</para>
|
|
|
|
<para>This package is known to behave badly when you have changed its default
|
|
optimization flags (including the -march and -mcpu options). Glibc is
|
|
best left alone, so we recommend you unsetting CFLAGS, CXXFLAGS and other
|
|
such variables/settings that would change the default optimization that
|
|
it comes with. Also, don't pass the --enable-kernel option to the configure
|
|
script. It's known to cause segmentation faults when other packages like
|
|
fileutils, make and tar are linked against it.</para>
|
|
|
|
<para>Basically, compiling Glibc in any way than this book suggests it, is
|
|
putting your system at very high risk.</para>
|
|
|
|
<para>Install Glibc by running the following commands:</para>
|
|
|
|
<para><screen><userinput>mknod -m 0666 /dev/null c 1 3 &&
|
|
touch /etc/ld.so.conf &&
|
|
cp malloc/Makefile malloc/Makefile.backup &&
|
|
sed 's%\$(PERL)%/usr/bin/perl%' malloc/Makefile.backup > malloc/Makefile &&
|
|
cp login/Makefile login/Makefile.backup &&
|
|
sed 's/root/0/' login/Makefile.backup > login/Makefile &&
|
|
mkdir ../glibc-build &&
|
|
cd ../glibc-build &&
|
|
../glibc-&glibc-version;/configure --prefix=/usr \
|
|
--enable-add-ons --libexecdir=/usr/bin &&
|
|
cp config.make config.make.backup &&
|
|
sed 's/cross-compiling = yes/cross-compiling = no/' \
|
|
config.make.backup > config.make &&
|
|
make &&
|
|
make install &&
|
|
make localedata/install-locales &&
|
|
exec /bin/bash --login</userinput></screen></para>
|
|
|
|
<para>An alternative to running <userinput>make
|
|
localedata/install-locales</userinput> is to only install those locales
|
|
which you need or want. This can be achieved using the localedef
|
|
command. Information on this can be found in the INSTALL
|
|
file in the glibc-&glibc-version; tree.</para>
|
|
|
|
<para>During the configure stage you will see the following warning:</para>
|
|
|
|
<blockquote><screen>configure: warning:
|
|
*** These auxiliary programs are missing or too old: msgfmt
|
|
*** some features will be disabled.
|
|
*** Check the INSTALL file for required versions.</screen></blockquote>
|
|
|
|
<para>The missing msgfmt (from the gettext package which we will install
|
|
later in this chapter) is not fatal. The files msgfmt would create are
|
|
already pre-built, so you won't be missing out on anything. You would
|
|
only need it if you make changes to the Glibc manual files. Since we
|
|
don't do this by default, we can safely ignore it.</para>
