Hello, it's been a while since I last was here to ask for help.

I am trying to create a CGI project but I can't find proper tutorials
for it.

However, I've managed to create something that compiles fine.

I am now trying to compile my CGI project on an ARMHF development
board and it seems to compile,
but i can't find where the compile CGI is located.

I run the following command on my dev board: fpc unit1.pas
all that happens is that two files are created, one called "unit1.ppu"
and the other is called "unit1.o".

Where is the compiled CGI?

I need to develop CGI for an ARM based CPU with Debian on it.

I am currently compiling from that board as well.

You are compiling a unit. Create another source file named test.pas
which contains these lines:
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
test;uses unit1; beginend.
Modify it as needed, compile it and now you should have a executable
binary.

You are an amazing person do you know that?

I don't know if I should start a new thread, but I don't know if I'm
using the CGI correctly.

My CGI code looks like this:

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 unit
Unit1; {$mode objfpc}{$H+} interface uses  SysUtils, Classes,
httpdefs, fpHTTP, fpWeb; type  TFPWebModule1 = class(TFPWebModule)   
procedure DataModuleRequest(Sender: TObject; ARequest: TRequest;
AResponse: TResponse; var Handled: Boolean);   private    { private
declarations }  public    { public declarations }  end; var 
FPWebModule1: TFPWebModule1; implementation {$R *.lfm} procedure
TFPWebModule1.DataModuleRequest(Sender: TObject; ARequest: TRequest; 
AResponse: TResponse; var Handled: Boolean);var  HexText, AsciiText:
string;begin // HexText := ARequest.QueryFields.Values['hex']; //
AsciiText := HexToAnsii(HexText);   AResponse.ContentType :=
'text/html;charset=utf-8'; //EDIT: I un-commented this line 
//AResponse.Contents.LoadFromFile(ExtractFilePath(ParamStr(0)) +
'mainpage.html');  //AResponse.Contents.Text :=
Format(AResponse.Contents.Text, [HexText, AsciiText]);  
AResponse.Contents.Text := 'Hello world!';  Handled :=
True;end; initialization  RegisterHTTPModule('TFPWebModule1',
TFPWebModule1);end.  
When I call a GET on it, I get a large string of text which seems to
contain the actual binary data of the CGI.

I do not receive the string "Hello world!" as expected.

I call a GET command with the path "<my server addr>/cgi-bin/test"
which is the correct path.

Should I call a POST action instead or what have I missed?

EDIT: I uncommented a specific line (please see the code again) but
this time the binary data is not returned, instead NOTHING is
returned.

I have also tried to call "/cgi-bin/test.cgi" instead of "/cgi-
bin/test".

Nothing is returned.

Read my tutorial. But obviously you need tutorial about HTTP and CGI
(and how it can be used in conjunction with web server, which also
requires its own reading after choosing an implementation, be it
Apache, Nginx, lighttpd, etc.) first, find them somewhere else.

Thanks for that tutorial.

I will read it.
