Nearly a week now, and I can't figure out what's wrong! Any pointers would be appreciated (pun intended)!

Ubuntu 12.04 x86_64

./configure --enable-64-bit --enable-pic -enable-opengl --enable-gles2 --enable-xorg --enable-egl --enable-glu --with-x

(Also tried with the apt-get package of Mesa)

ls /usr/local/lib | grep EGL  

When running the simple tutorial code

display = eglGetDisplay(EGL_DEFAULT_DISPLAY);  
EGLBoolean err = eglInitialize(display, NULL, NULL);

initialize fails and further functions return EGL_NOT_INITIALIZED.

apt-get install libxcb-xfixes0-dev libxcb-dri2-0-dev helps building the Mesa. – Vorac Nov 21 '12 at 14:33

Under an X desktop, you cannot use EGL_DEFAULT_DISPLAY. You must pass to eglGetDisplay() a pointer to a valid Xlib Display. For example:

EGLBoolean ok;

Display *xlib_dpy = XOpenDisplay(NULL);
if (!xlib_dpy)

EGLDisplay egl_dpy = eglGetDisplay(xlib_dpy);
if (!egl_dpy)

int major;
int minor;
ok = eglInitialize(egl_dpy, &major, &minor);
if (!ok)

if (10 * major + minor != 14) {
  /* EGL is too old; */
