| 13 | <p> |
| 14 | The current version of the OpenVG state tracker implements OpenVG 1.0. |

| 22 | The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation. |
| 23 | </p> |
| 24 | |
| 25 | |
| 26 | <h2>Building the library</h2> |
| 27 | <ol> |
| 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> |
| 31 | </ol> |
| 32 | |
| 33 | <h3>Sample build</h3> |
| 34 | A sample build looks as follows: |
| 35 | <pre> |
| Brian Paul | d6318ba | 2009-05-01 11:37:09 -0600 | [diff] [blame^] | 36 | make linux-x86-64-debug |
| 37 | cd src/gallium/state_trackers/vega |
| 38 | make |
| 39 | cd ../../../.. |
| 40 | export LD_LIBRARY_PATH=$PWD/lib64 |
| 41 | export EGL_DRIVER="egl_softpipe" |

| 45 | |
| 46 | <p> |
| 47 | To build the OpenVG demos: |
| 48 | </p> |
| 49 | <pre> |
| 50 | cd progs/openvg |
| 51 | make |
| 52 | </pre> |
| 53 | <p> |
| 54 | To run a demo: |
| 55 | </p> |
| 56 | <pre> |
| 57 | cd openvg/demos |
| 58 | ./lion |
| 59 | </pre> |

| 63 | <ul> |
| 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> |
| 65 | </ul> |
