<p>This document provides <em>usage</em> information about the LLVM makefile
|
|
|
|
|
system. While loosely patterned after the BSD makefile system, LLVM has taken
|
2004-10-25 19:28:03 +00:00
|
|
|
a departure from BSD in order to implement additional features needed by LLVM.
|
2004-10-23 07:57:22 +00:00

|
|
</p>
|
|
|
|
|
<p>Although makefile systems such as automake were attempted at one point, it
|
2004-10-25 19:37:46 +00:00
|
|
|
has become clear that the differences between the LLVM way of doing things and
|
|
|
|
|
the Makefile norm are too great to use a more limited tool. Consequently, LLVM requires
|
2004-10-23 07:57:22 +00:00
|
|
|
simply GNU Make 3.79, a widely portably 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>
|
|
|
|
|
<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
|
|
|
|
|
early source of bewilderment for new developers.</p>

<p>The LLVM makefile system is the component of LLVM that is responsible for

building the software, testing it, generating distributions, rpms and other

<p>The LLVM Makefile System is quite generous. It not only builds its own
|
|
|
|
|
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 get up and running quickly by utilizing the built-in features that are used
|
|
|
|
|
to compile LLVM.</p>
