native-prism-es2/monocle has a file eglUtils.c that has
#include "eglfb/wrapped_egl.h"

The header file is taken from native-prism-es2/eglfb but there is no implementation of this in native-prism-es2/monocle. There is a similar file eglUtils.c in the eglfb directory, so I think either the monocle directory should have wrapped_egl.c as well, or the 2 directories need to be merged
