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> </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" </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> <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> </body> </html>
