| 32 | <p>This section describes how to aquire and build llvm-gcc4, which is based on |
| 33 | the GCC 4.0.1 front-end. This front-end supports C, C++, Objective-C, and |
| 34 | Objective-C++. Note that the instructions for building this front-end are |
| 35 | completely different (and much easier!) than those for building llvm-gcc3 in |
| 36 | the past.</p> |
| 37 | |
| 38 | <ol> |
| 39 | <li><p>Retrieve the appropriate llvm-gcc4-x.y.source.tar.gz archive from the |
| 40 | <a href="http://llvm.org/releases/">llvm web site</a>.</p> |
| 41 | |
| 42 | <p>It is also possible to download the sources of the llvm-gcc4 front end |
| 43 | from a read-only mirror using subversion. To check out the code the |
| 44 | first time use:</p> |
| 45 | |
| 46 | <div class="doc_code"> |
| 47 | <pre> |
| 48 | svn co svn://anonsvn.opensource.apple.com/svn/llvm/trunk <i>dst-directory</i> |
| 49 | </pre> |
| 50 | </div> |
| 51 | |
| 52 | <p>After that, the code can be be updated in the destination directory |
| 53 | using:</p> |
| 54 | |
| 55 | <div class="doc_code"> |
| 56 | <pre>svn update</pre> |
| 57 | </div> |
| 58 | |
| 59 | <p>The mirror is brought up to date every evening.</p></li> |
| 60 | |
| 61 | <li>Follow the directions in the top-level <tt>README.LLVM</tt> file for |
| 62 | up-to-date instructions on how to build llvm-gcc4.</li> |
| 63 | </ol> |
