Re: Creating PDF reports

[Steven LeMaire]

I gave it a go with Xvfb, by first setting up the display like so:

export DISPLAY=:1
Xvfb :1 -screen 0 1024x768x16 &

Then running the program (in gdb), but it breaks unfortunately:

Breakpoint 1, main (argc=1, argv=0xbfffeed4) at main.m:14
14         id pool = [[NSAutoreleasePool alloc] init]; 
(gdb) n
17         app = [NSApplication sharedApplication];
(gdb) n

Did i do something wrong ? I also tried using NSAttributedString hoping to try 
and make RTF instead, but it seems to have the same X requirements
