Glibc installation Glibc will check for the /etc/ld.so.conf file and abort with an error if the file is missing, so we must create it: touch /etc/ld.so.conf The documentation that comes with Glibc recommends to build the package not in the source directory but in a separate, dedicated directory: mkdir ../glibc-build && cd ../glibc-build Next, prepare Glibc to be compiled: CFLAGS="-O2 -pipe" \     ../glibc-&glibc-version;/configure --prefix=/usr \     --disable-profile --enable-add-ons \     --libexecdir=/usr/bin \     --with-headers=/usr/include \     --mandir=/usr/share/man --infodir=/usr/share/info The meaning of the configure options are: --disable-profile: This disables the building of the libraries with profiling information. Omit this option if you plan to do profiling. --enable-add-ons: This enables any add-ons that we installed with Glibc, in our case Linuxthreads. --libexecdir=/usr/bin: This will cause the pt_chown program to be installed in the /usr/bin directory. During this stage you will see the following warning:
configure: warning: *** These auxiliary programs are missing or too old: msgfmt *** some features will be disabled. *** Check the INSTALL file for required versions.
The missing msgfmt program (from the Gettext package, which we'll install later) won't cause any problems. The msgfmt is used to generate the binary translation files that can make your system talk in a different language. Because these translation files have already been generated for you, there is no need for msgfmt. You'd only need the program if you change the translation source files (the *.po files in the po subdirectory), which would require you to regenerate the binary files. Because Glibc hasn't been installed yet, one of the tests that was run by the configure script has failed. This test is supposed to test gcc to determine whether a cross-compiler is installed. However, Glibc needs to be already installed to run this test. Since the test failed, the configure script assumes we have a cross-compiler. We override that assumption by explicitly telling Glibc we're not cross-compiling. Not doing this would have a couple of unintended side effects, such as the timezone files not being installed. echo "cross-compiling = no" > configparms Continue with compiling the package: make We'll continue with installing the package. The Linuxthreads man pages are not going to be installed at this point because it requires a working Perl installation. We'll install Perl later on in this chapter, and the man pages will be installed when Glibc is installed for the second time at the end of this chapter. make check make install The locales (used by Glibc to make your Linux system talk in a different language) weren't installed when you ran the previous command, so we have to do that ourselves now: make localedata/install-locales An alternative to running the previous command is to install only 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. To finish off the installation we'll reload Bash so it will use the new libnss_* files. This will also get rid of the I have no name! message in the command prompt: exec /static/bin/bash --login
