11 <H1>OpenVG State Tracker</H1>
14 The current version of the OpenVG state tracker implements OpenVG 1.0.
17 More informations about OpenVG can be found at

19 http://www.khronos.org/openvg/</a> .
22 The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation.
26 <h2>Building the library</h2>
28 <li>Build Mesa3D with Gallium3D. Any build that builds Gallium3D libraries and EGL will suffice</li>
29 <li>cd src/gallium/state_trackers/vega; make</li>
30 <li>The last step will build libOpenVG library. You can add the libdir to LD_LIBRARY_PATH or install libOpenVG</li>
34 A sample build looks as follows:
36 make linux-x86-64-debug
37 cd src/gallium/state_trackers/vega
40 export LD_LIBRARY_PATH=$PWD/lib64
41 export EGL_DRIVER="egl_softpipe"
47 To build the OpenVG demos:
64 <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>
