Installation of GCC on the normal system if necessary In order to compile Glibc-2.1.3 later on you need to have gcc-2.95.2 installed. Although any GCC version above 2.8 would do, 2.95.2 is the highly recommended version to use. egcs-2.91.x is also known to work. If you don't have gcc-2.95.x or egcs-2.91.x you need to install gcc-2.95.2 on your normal sytem before you can compile Glibc later in this chapter. To find out which compiler version your systems has, run the following command:
gcc --version
If you normal Linux system does not have gcc-2.95.x or egcs-2.91.x installed you need to install it now. We won't replace the current compiler on your system, but instead we will install gcc in a separate directory (/usr/local/gcc2952). This way no binaries or header files will be replaced. After you unpacked the gcc-2.95.2 archive don't enter the newly created gcc-2.95.2 directory but stay in the $LFS/usr/src directory. Install GCC by running the following commands:
mkdir $LFS/usr/src/gcc-build && cd $LFS/usr/src/gcc-build && ../gcc-2.95.2/configure \    --prefix=/usr/local/gcc2952 \    --with-local-prefix=/usr/local/gcc2952 \    --with-gxx-include-dir=/usr/local/gcc2952/include/g++ \    --enable-shared --enable-languages=c,c++ && make bootstrap && make install
