| <h1>Getting Started: Building and Running VMKit</h1> |
| |
| |
| <p>This page gives you the shortest path to checking out vmkit and demos a few |
| options. This should get you up and running with the minimum of muss and fuss. |
| If you like what you see, please consider <a href="get_involved.html">getting |
| involved</a> with the vmkit community.</p> |
| |
| <h2 id="build">Building vmkit / working with the code</h2> |
| |
| <p>If you would like to check out and build the project, the current scheme |
| is:</p> |
| |
| <p><b>Prerequisites</b><br/> |
| You will have to install a C++ compiler and Java 1.5 or more in order to |
| compile vmkit2</p> |
| |
| <ol> |
| <li>Download <a href="http://llvm.org/releases/3.3/llvm-3.3.src.tar.gz"> |
| LLVM 3.3</a> and |
| <a href="http://llvm.org/releases/3.3/cfe-3.3.src.tar.gz">Clang 3.3</a> |
| source code. |
| </li> |
| |
| <ul> |
| <li><tt>tar zxvf llvm-3.3.src.tar.gz</tt></li> |
| <li><tt>cd llvm-3.3.src/tools</li></tt> |
| <li><tt>tar zxvf ../../cfe-3.3.src.tar.gz</tt></li> |
| <li><tt>mv cfe-3.3.src clang</li></tt> |
| <li><tt>cd ..</li></tt> |
| <li><tt>./configure --enable-optimized; make</tt></li> |
| </ul> |
| <br>Note: To compile LLVM and VMKit with RTTI enabled, one can pass the parameter |
| REQUIRES_RTTI=1 to llvm make. Passing this argument removes the flag -fno-rtti from |
| the compiler options. Ex: $ make REQUIRES_RTTI=1 |
| |
| <p><b>Skip the Classpath steps if you plan to use OpenJDK.</b><br/> |
| <li><a href="ftp://ftp.gnu.org/gnu/classpath/classpath-0.99.tar.gz">Download |
| GNU Classpath 0.99</a>:</li> |
| |

| <li><tt>./configure --disable-plugin --disable-examples --disable-Werror; |
| make</tt></li> |
