26<h2>Building the library</h2>
27<ol>
28<li>Run <code>configure</code> with <code>--enable-openvg</code> and
29<code>--enable-gallium-egl</code>.  If you do not need OpenGL, you can add
30<code>--disable-opengl</code> to save the compilation time.</li>
31
32<li>Build and install Mesa as usual.</li>
33</ol>

35<h3>Sample build</h3>
36A sample build looks as follows:
37<pre>
38  $ /configure --disable-opengl --enable-openvg --enable-gallium-egl
39  $ make
