<title>Introduction to 
<application><acronym>GCC</acronym></application>-&gcc3-version;</title>

<para>The reason for installing 
<application><acronym>GCC</acronym></application>-&gcc3-version; is that 
some <acronym>BLFS</acronym> packages (such as compiled 
<application>Java</application> and <application>OpenOffice</application>) 
have not been updated to be compilable by 
<application><acronym>GCC</acronym></application>-&gcc-version;. Additionally, 
some pre-compiled packages may require the 
<application><acronym>GCC</acronym></application>-&gcc3-version; 
libraries.</para>

<title>Command explanations</title>

<para><command>mkdir ../gcc-build; cd ../gcc-build</command>: The 
<application><acronym>GCC</acronym></application> development team recommends 
building in a separate directory.</para>

<para><parameter>--enable-shared --enable-languages=c,c++ 
--enable-threads=posix</parameter>: Configures 
<application><acronym>GCC</acronym></application> to build the 
<application>C</application> and <application>C++</application> compilers and 
enable the related <application>C++</application> options.</para>

<para><command>mv /opt/gcc-&gcc3-version;/lib/libstdc++.so.5* 
/usr/lib</command>: Moves the <application>C++</application> libraries to the 
standard lib directory to avoid having to add 
<userinput>/opt/gcc-&gcc3-version;/lib</userinput> to 
<filename>/etc/ld.so.conf</filename>.</para>

<para>If you only need the GCC-&gcc3-version; libraries, you may delete
<filename>/opt/gcc-&gcc3-version;</filename>.</para>

<para>Whenever you need to use GCC-&gcc3-version; instead of your system
installed compiler, add
<filename class="directory">/opt/gcc-&gcc3-version;/bin</filename> to the 
front of your <envar>PATH</envar> or (preferably) set the <envar>CC</envar>
environment variable before compiling the concerned package.</para>
