I haven't tried that for a while, but it should not have X11 dependencies. You probably need to disable other stuffs such as --disable-glx and etc. It might still require X11 at compile time, because eglplatform.h may include Xlib.h, but it should not need X11 at runtime.
But you need to modify the app to use pbuffer or FBO. Or you may add some code to the null platform to treat windows as pbuffers. > > >> You won't be able to ask it to render to an application-provided buffer >> though. > > Not sure what do you mean by application provided buffer? You cannot allocate a buffer in the app and ask the driver to render to it, mainly due to alignment requirements. > > Thanks & Regards, > Divick -- o...@lunarg.com _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
