(Awesomium:30033): Gtk-WARNING **: cannot open display on linux

[dongjiahong]

hi:
I'm trying to get the linux SDK to work. It can be compiled well.
I go to run it and i get this warning and error:

 (Awesomium:30033): Gtk-WARNING **: cannot open display:
[0100/000000:ERROR:zygote_main_linux.cc(527)] write: Broken pipe

I get an answer in answers.awesomium.com .
So i run it and i get errors too:

$  xvfb-run ./main

/usr/bin/xvfb-run: line 181: 30064 Segmentation fault   DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1

Not sure whats going on here, I thought this was supposed to be a headless environment? Is there any way I can get awesomium to work on linux without X ?

environment:

# head -n 1 /etc/issue
CentOS release 6.8 (Final)

# gcc -v
Using built-in specs.
