5.7.1. Installation of Glibc

Fix a bug that prevents Glibc from building with GCC-4.5.2:

patch -Np1 -i ../glibc-2.13-gcc_fix-1.patch
The Glibc documentation recommends building Glibc outside of the source directory in a dedicated build directory:

mkdir -v ../glibc-build
cd ../glibc-build
Because Glibc no longer supports i386, its developers say to use the compiler flag -march=i486 when building it for x86 machines. There are several ways to accomplish that, but testing shows that the flag is best placed inside the build variable “CFLAGS”. Instead of overriding completely what Glibc's internal build system uses for CFLAGS, append the new flag to the existing contents of CFLAGS by making use of the special file configparms. The -mtune=native flag is also necessary to reset a reasonable value for -mtune that is changed when setting -march.

case `uname -m` in
i?86) echo "CFLAGS += -march=i486 -mtune=native" > configparms ;;
esac
Next, prepare Glibc for compilation:

../glibc-2.13/configure --prefix=/tools \
--host=$LFS_TGT --build=$(../glibc-2.13/scripts/config.guess) \
--disable-profile --enable-add-ons \
--enable-kernel=2.6.22.5 --with-headers=/tools/include \
libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes
The meaning of the configure options:

--host=$LFS_TGT, --build=$(../glibc-2.13/scripts/config.guess)
The combined effect of these switches is that Glibc's build system configures itself to cross-compile, using the cross-linker and cross-compiler in /tools.
--disable-profile
This builds the libraries without profiling information. Omit this option if profiling on the temporary tools is necessary.
--enable-add-ons
This tells Glibc to use the NPTL add-on as its threading library.
--enable-kernel=2.6.22.5
This tells Glibc to compile the library with support for 2.6.22.5 and later Linux kernels. Workarounds for older kernels are not enabled.
--with-headers=/tools/include
This tells Glibc to compile itself against the headers recently installed to the tools directory, so that it knows exactly what features the kernel has and can optimize itself accordingly.
libc_cv_forced_unwind=yes
The linker installed during Section 5.4, “Binutils-2.21 - Pass 1” was cross-compiled and as such cannot be used until Glibc has been installed. This means that the configure test for force-unwind support will fail, as it relies on a working linker. The libc_cv_forced_unwind=yes variable is passed in order to inform configure that force-unwind support is available without it having to run the test.
libc_cv_c_cleanup=yes
Simlarly, we pass libc_cv_c_cleanup=yes through to the configure script so that the test is skipped and C cleanup handling support is configured.
During this stage the following warning might appear:

configure: WARNING:
*** These auxiliary programs are missing or
*** incompatible versions: msgfmt
*** some features will be disabled.
*** Check the INSTALL file for required versions.
The missing or incompatible msgfmt program is generally harmless. This msgfmt program is part of the Gettext package which the host distribution should provide.

Compile the package:

make
This package does come with a test suite, however, it cannot be run at this time because we do not have a C++ compiler yet.

Note
The test suite also requires locale data to be installed in order to run successfully. Locale data provides information to the system regarding such things as the date, time, and currency formats accepted and output by system utilities. If the test suites are not being run in this chapter (as per the recommendation), there is no need to install the locales now. The appropriate locales will be installed in the next chapter. To install the Glibc locales anyway, use instructions from Section 6.9, “Glibc-2.13.”

Install the package:

make install
Details on this package are located in Section 6.9.4, “Contents of Glibc.”
