Im using EGL 1.2 implemented on a TI OMAP.  The code i posted was more or less the full file apart from the includes which were:

#include <cairo.h>
#include <cairo-vg.h>
#include <EGL/egl.h>
#include <stdlib.h>

It compiles without errors with the following:

export PREFIX=/opt/omap
export PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig
arm-none-linux-gnueabi-gcc -Wall `pkg-config --cflags --libs cairo freetype2 fontconfig pixman-1 libxml-2.0` -lpng12 -lz -L$PREFIX/lib -lEGL -lIMGegl 
-lsrv_um -lGLESv2 -lGLES_CM -lOpenVG -lOpenVGU -I$PREFIX/include -I$PREFIX/include/cairo -I$PREFIX/include/OVG -o testcairovg testcairovg.c

On the target, it runs but nothing is drawn on screen.  Cairo works fine when drawing to an image surface.

Thanx for your time, Paul
