Ah, I was thinking you would still run on that machine, but just set DISPLAY to a machine that has an Xserver.

Hi,

 

Nope this is running in a production server that is intended to run headless. I started a dumb X server on it, and it works but it's not the best option.

Can you just point yourself at another X server somewhere? A desktop/workstation?

Hi List,

 

That code, running on my headless (no X) server, is crashing pathetically:

 

chloe@ayodhya:~/pdfparser$ cat test.rb

begin

require 'gtk2'

rescue Gtk::InitError

end

require "poppler"

 

buf = Gdk::Pixbuf.new(Gdk::Pixbuf::COLORSPACE_RGB, true, 8, 1024, 768)

 

# copy the rendered buffer into an pixmap for further editing

map = Gdk::Pixmap.new(nil, 1024, 768, 24)

map.draw_pixbuf(nil, buf, 0, 0, 0, 0, -1, -1, Gdk::RGB::DITHER_NONE, 0, 0)

 

Like that:

chloe@ayodhya:~/pdfparser$ ruby  test.rb

test.rb: line 10

   Gdk-CRITICAL **:IA__gdk_screen_get_root_window: assertion `GDK_IS_SCREEN (screen)' failed

test.rb: line 10

   Gdk-CRITICAL **:IA__gdk_drawable_get_depth: assertion `GDK_IS_DRAWABLE (drawable)' failed

Segmentation fault


I don't like much the idea of running an X server just for running that piece of software but feel like I'll have to.

 

Any insight?

 

Thanks

Chloé
