Hi, OpenVG is implemented as a state tracker for Gallium3D, so only Gallium3D drivers are able to use it. Pineview is i915, so in order to use OpenVG you'll have to use the Gallium/i915 driver that isn't maintained by Intel. (Intel maintains the "classic"-style i915 driver) I'd try to configure with these options: ./configure --with-dri-drivers= --with-gallium-drivers=i915 --enable-gallium-llvm --enable-openvg --enable-gallium-egl (--enable-gallium-llvm gives i915 better performance, but adds the dependency of LLVM) You might be able to avoid some dependencies by adding --disable-opengl --disable-gles1 --disable-gles2 --disable-dri --disable-glx but I'm not really sure how Gallium works, so you might need DRI to get any acceleration. libdrm built with Intel support, which Gallium/i915 needs, does indeed depend on libpciaccess. libpciaccess is a rather small library though. I wouldn't expect trouble with it. Matt _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
