Make 3.79, a widely portable makefile processor. LLVM unabashedly makes heavy
use of the features of GNU Make so the dependency on GNU Make is firm. If
you're not familiar with <tt>make</tt>, it is recommended that you read the
- <a href="http://www.gnu.org/software/make/manual/make.html">GNU Makefile Manual
- </a>.</p>
+ <a href="http://www.gnu.org/software/make/manual/make.html">GNU Makefile
+ Manual</a>.</p>
<p>While this document is rightly part of the
<a href="ProgrammersManual.html">LLVM Programmer's Manual</a>, it is treated
separately here because of the volume of content and because it is often an
software, but it can build yours too. Built into the system is knowledge of
the <tt>llvm/projects</tt> directory. Any directory under <tt>projects</tt>
that has both a <tt>configure</tt> script and a <tt>Makefile</tt> is assumed
- to be a project that uses the LLVM Makefile system. This allows your project
+ to be a project that uses the LLVM Makefile system. Building software that
+ uses LLVM does not require the LLVM Makefile System nor even placement in the
+ <tt>llvm/projects</tt> directory. However, doing so will allow your project
to get up and running quickly by utilizing the built-in features that are used
to compile LLVM. LLVM compiles itself using the same features of the makefile
system as used for projects.</p>
