<title>Introduction to <application><acronym>GCC</acronym></application>-&gcc2-version;</title>
|
|
|
|
<para>There are two reasons for installing
|
|
<acronym>GCC</acronym>-&gcc2-version;. The first is that the kernel
|
|
developers have certified <acronym>GCC</acronym>-&gcc2-version; as the
|
|
preferred compiler for compiling the kernel. The other (and more compelling
|
|
reason) is that some commercial closed-source packages (such as Netscape
|
|
Navigator, Yahoo Pager) and precompiled packages (such as Mozilla)
|
|
are linked against <acronym>GCC</acronym>-&gcc2-version; libs.</para>
