Well, at least its baffling to me...

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 const  {$if
defined(windows)}  FSPrefix: String = 'C:';  {$endif}  {$if
defined(linux)}  FSPrefix: String = 'file:/home/simon';  {$endif} 
{$if defined(darwin)}  FSPrefix: String = 'file:/Users/simon'; 
{$endif}  ModelFile: String = FSPrefix + PathDelim + 'Assets' +
PathDelim + 'GreenDragon.glb';
Error: Illegal expression

Since the constanst you define are in effect initialize variables, you
cannot use them to build other constants at design time.
Just skip the ": string" part for FSPrefix (and perhaps also in
ModelFile, unless you need to change that at runtime) in the
declaration.
The compiler knows that '/foo' is a string ;-)

This should do:

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     const 
   {$if defined(windows)}      FSPrefix = 'C:';      {$endif}     
{$if defined(linux)}      FSPrefix = 'file:/home/simon';     
{$endif}      {$if defined(darwin)}      FSPrefix =
'file:/Users/simon';      {$endif}      ModelFile: String = FSPrefix +
PathDelim + 'Assets' + PathDelim + 'GreenDragon.glb';
