<h3><a name="shared">Access to <tt>/shared</tt></a></h3>
<!------------------------------------------------------------------------->
By default, LLVM is configured to send all compiled files into the
<tt>/shared/[yourloginname]/</tt> directory. The idea is that this
directory is local to the machine you're working on, so the huge libraries
and <tt>.o</tt> files you will be compiling will not have to be sent over
NFS. If you are in a situation where this setup is correct, you don't have
to do anything. If you don't have a <tt>/shared</tt> directory, you will
have to make a couple of modifications to your setup.<p>
The first modification is that you need to enable the "<tt>BUILD_ROOT =
.</tt> line in the top level <tt>Makefile.common</tt>. This will instruct
LLVM to build into the current directory tree instead of
<tt>/shared</tt>.<p>
