Installation of Glibc 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. Install Glibc by running the following commands: mknod -m 0666 /dev/null c 1 3 && touch /etc/ld.so.conf && cp -f malloc/Makefile \    malloc/Makefile.backup && sed 's%\$(PERL)%/usr/bin/perl%' \    malloc/Makefile > tmp~ && mv -f tmp~ malloc/Makefile && cp -f login/Makefile \    login/Makefile.backup && sed 's/root/0/' login/Makefile > tmp~ && mv -f tmp~ login/Makefile && mkdir ../glibc-build && cd ../glibc-build && ../glibc-&glibc-version;/configure \    --prefix=/usr --enable-add-ons \    --libexecdir=/usr/bin && cp -f config.make config.make.backup && sed 's/cross-compiling = yes/cross-compiling = no/' \    config.make > tmp~ && mv -f tmp~ config.make && make && make install && make localedata/install-locales && exec /bin/bash During the configure stage you will see the following warning:
configure: warning: *** An auxiliary program is missing or too old; *** some features will be disabled. *** Check the INSTALL file for required versions.
This warning refers to the missing msgfmt program from the gettext package, but it can safely be ignored in our case. The glibc installation will not be affected.
