I think the best solution is to detect the support for the egl platform extension in the header, and this should be a trivial fix. <div class="gmail_quote">On Apr 18, 2014 10:13 AM, "Ilia Mirkin" <<a href="mailto:imirkin@alum.mit.edu">imirkin@alum.mit.edu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi Chad, I've recently started getting build errors on piglit, and have narrowed it down to your commit 6b71f217052 ("util/egl: Add piglit_egl_get_default_display()"). The build error I'm getting is tests/util/piglit-util-egl.c: In function 'piglit_egl_get_default_display': tests/util/piglit-util-egl.c:111:7: error: 'EGL_PLATFORM_X11_EXT' undeclared (first use in this function) tests/util/piglit-util-egl.c:111:7: note: each undeclared identifier is reported only once for each function it appears in tests/util/piglit-util-egl.c:116:7: error: 'EGL_PLATFORM_WAYLAND_EXT' undeclared (first use in this function) tests/util/piglit-util-egl.c:121:7: error: 'EGL_PLATFORM_GBM_MESA' undeclared (first use in this function) make[2]: *** [target_api/no_api/tests/util/CMakeFiles/piglitutil.dir/piglit-util-egl.c.o] Error 1 And indeed, these defines do not exist in my system eglext.h (which comes from Mesa 10.0.4). They do, however, appear in the mesa git one. I think it's a little annoying to force people to build against the very latest EGL headers, but I guess it's not the worst thing in the world either. However I was hoping there'd be a way to not force that, for convenience. I'm not well-enough versed in (E)GL to know how to deal with this though. Any ideas? -ilia _______________________________________________ Piglit mailing list <a href="mailto:Piglit@lists.freedesktop.org">Piglit@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/piglit" target="_blank">http://lists.freedesktop.org/mailman/listinfo/piglit</a> </blockquote></div>
