hello...
i'm on linux 64 bit (ubuntu) when i'm trying to compile the following
code I get an error about a missing lib

here is the code:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
Project1; { Program to demonstrate static graphics mode selection
} uses ptcgraph;  const  TheLine = 'We are now in 640 x 480 x 256
colors!'+            ' (press <Return> to continue)'; var  gd, gm, lo,
hi, error,tw,th: Smallint;  found: boolean; begin  { We want an 8 bit
mode }  gd := D8bit;  gm := m640x480;  initgraph(gd,gm,'');  { Make
sure you always check graphresult! }  error := graphResult;  if (error
<> grOk) Then    begin    writeln('640x480x256 is not supported!');  
halt(1)    end;  { We are now in 640x480x256 }  setColor(cyan); 
rectangle(0,0,getmaxx,getmaxy);  { Write a nice message in the center
of the screen }  setTextStyle(defaultFont,horizDir,1); 
tw:=TextWidth(TheLine);  th:=TextHeight(TheLine);  outTextXY((getMaxX
- TW) div 2,            (getMaxY - TH) div 2,TheLine);  { Wait for
return }  readln;  { Back to text mode }  closegraph;end. 
here is the error massage:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i linker:
/usr/bin/ld: cannot find -lXxf86dga
what is this libxxf86dga library and what do I have to do in order to
get it so I can use ptcgraph unit?

thank you...

it seems i found the answer

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i $ sudo apt-
get install libxxf86dga-dev 
now the code compiles and run with out error yet I can't see a window
or console
