<title>Installation of GCC on the normal system if necessary</title>

<para>
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.
</para>

<para>
To find out which compiler version your systems has, run the
following command:
</para>

<blockquote><literallayout>

        <userinput>gcc --version</userinput>

</literallayout></blockquote>

<para>
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.
</para>

<para>
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:
</para>

<blockquote><literallayout>

        <userinput>mkdir $LFS/usr/src/gcc-build &amp;&amp;</userinput>
        <userinput>cd $LFS/usr/src/gcc-build &amp;&amp;</userinput>
        <userinput>../gcc-2.95.2/configure \</userinput>
        <userinput>&nbsp;&nbsp;&nbsp;--prefix=/usr/local/gcc2952 \</userinput>
        <userinput>&nbsp;&nbsp;&nbsp;--with-local-prefix=/usr/local/gcc2952 
                \</userinput>
        <userinput>&nbsp;&nbsp;
                --with-gxx-include-dir=/usr/local/gcc2952/include/g++ \</userinput>
        <userinput>&nbsp;&nbsp;&nbsp;--enable-shared --enable-languages=c,c++
                 &amp;&amp;</userinput>
        <userinput>make bootstrap &amp;&amp;</userinput>
        <userinput>make install</userinput>
