External Pascal in Inno script which gives Unknown Preprocessor directive

Question

I am trying to use the Synopse JSON library in Inno Setup. I am getting an unknown preprocessor directive.

Obviously Inno Setup uses a limited form of Pascal which doesn't include things that Synopse is using. My question is, is there a way to compile the Synopse library or otherwise transform the file so that I can still call it as an external library? I don't want to go in and mess with the Synopse code-I think the code its complaining about is fairly crucial, anyways.

Minimal example which generates error (script is in same dir as a folder called lib which contains the *.pas):

#define MyAppName "Minimal"
#define MyAppVersion "2.0"


[Setup]
; NOTE: The value of AppId uniquely identifies this application.
; Do not use the same AppId value in installers for other applications.
; (To generate a new GUID, click Tools | Generate GUID inside the IDE.)

AppName={#MyAppName}
AppVersion={#MyAppVersion}
AppVerName={#MyAppName}


[Code]
#include "lib\SynCrossPlatformJSON.pas"

That message sounds more like an problem in your innosetup file. Could you post it? — Marco Rebsamen, Sep 22 '16 at 14:35
You cannot use random Pascal code in Inno Setup. The Pascal Script is too limited. In particular, you cannot define your own classes. — Martin Prikryl, Sep 22 '16 at 14:37
@MartinPrikryl. I'm aware. I'm asking how I can take this .pas file to a form more palatable to inno setup. — Nils Guillermin, Sep 22 '16 at 14:43
The Synopse code uses classes and pointers - Inno Setup Pascal Script does not support classes nor pointers - You *don't want to go in and mess with the Synopse code* => **Do not use Synopse code** — Martin Prikryl, Sep 22 '16 at 14:44
Sure, but you would have to export a function for every method you use from the library. Why don't you use existing JSON libraries for Inno Setup? — Martin Prikryl, Sep 22 '16 at 14:46
I apparently zoned out when looking at koldev's github. I'll use that. Thanks for your patience. — Nils Guillermin, Sep 22 '16 at 14:51
I don't think I have enough rep, I have flagged it as dup though. — Nils Guillermin, Sep 22 '16 at 15:00
