The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation.

< 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 >

A sample build looks as follows:

make linux-x86-64-debug
cd src/gallium/state_trackers/vega
make
cd ../../../..
export LD_LIBRARY_PATH=$PWD/lib64
export EGL_DRIVER="egl_softpipe"

< 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 >
