+<h1>OpenVG State Tracker</h1>
<p>
-The current version of the OpenVG state tracker implements OpenVG 1.0.
+The current version of the OpenVG state tracker implements OpenVG 1.1.
</p>
<p>
More informations about OpenVG can be found at
-<a href="http://www.khronos.org/openvg/" target="_parent">

</p>
<p>
The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation.
+Please refer to <a href="egl.html">Mesa EGL</a> for more information about EGL.
</p>
<h2>Building the library</h2>
<ol>
-<li>Build Mesa3D with Gallium3D. Any build that builds Gallium3D libraries and EGL will suffice</li>
-<li>cd src/gallium/state_trackers/vega; make</li>
-<li>The last step will build libOpenVG library. You can add the libdir to LD_LIBRARY_PATH or install libOpenVG</li>
+<li>Run <code>configure</code> with <code>--enable-openvg</code> and
+<code>--enable-gallium-egl</code>. If you do not need OpenGL, you can add
+<code>--disable-opengl</code> to save the compilation time.</li>
+
+<li>Build and install Mesa as usual.</li>
</ol>
<h3>Sample build</h3>
A sample build looks as follows:
<pre>
- make linux-x86-64-debug
- cd src/gallium/state_trackers/vega
- make
- cd ../../../..
- export LD_LIBRARY_PATH=$PWD/lib64
- export EGL_DRIVER="egl_softpipe"
+ $ ./configure --disable-opengl --enable-openvg --enable-gallium-egl
+ $ make
+ $ make install
</pre>
-<h2>OpenVG Demos</h2>
-
-<p>
-To build the OpenVG demos:
-</p>
-<pre>
- cd progs/openvg
- make
-</pre>
-<p>
-To run a demo:
-</p>
-<pre>
- cd openvg/demos
- ./lion
-</pre>
+<p>It will install <code>libOpenVG.so</code>, <code>libEGL.so</code>, and one
+or more EGL drivers.</p>
+<h2>OpenVG Demos</h2>
-<h2>Notes</h2>
-<ul>
-<li>EGL_DRIVER environmental variable: forces usage of a specific EGL driver. Unless you force egl_softpipe the implementation will look for a DRI hardware accelerate driver and unless you have a Gallium driver that supports it, you'll see crashes</li>
-</ul>
+<p>OpenVG demos can be found in mesa/demos repository.</p>
