<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 --with-state-trackers=egl_g3d,vega --enable-gallium-intel

<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>
