What is covered, what not?

Installing Free Pascal on Mac If you use Mac OS X, the easiest way to use Free Pascal is to download the Xcode development environment from Apple's web site and follow the simple installation instructions. Once you have Xcode setup, you will be able to use the Free Pascal compiler. Installing Free Pascal on Windows. Although Lazarus is targeted mainly for Linux and Windows operating systems, there are also binary packages available for Mac OS X. FreeBSD makes Free Pascal and Lazarus available through its ports collections. It is also possible to run Lazarus on other operating systems, such as Haiku, by compiling Lazarus and Free Pascal from source.

Free Pascal IDE or Lazarus IDE

IDE stands for integrated development environment. Although you could write your programs in a simple text editor, an IDE makes your life much easier. For example, it highlights keywords, makes it easier for you to set up the compiler, and much more. Now let’s have a look at these two IDEs:

You may notice that the native Free Pascal IDE (left) looks old, but it is shipped right along with the Free Pascal Compiler. In contrast to that the Lazarus IDE (right) looks up-to-date, but requires it to be installed additionally. My advise is nonetheless, use the Lazarus IDE.

The Free Pascal Compiler (FPC)

We need three different software packages. First of all we need the stand-alone Free Pascal Compiler or Lazaruse IDE (which already has a copy of the Free Pascal Compiler included). If you are not sure, I recommend to go with the Lazarus IDE package.

SDL Library and SDL 2.0 units

Additionaly we need the original SDL library files (.dll files). And finally we need units that connect our SDL 2.0 code written in Free Pascal to the SDL library files. The latter will be done by SDL 2.0 units.

This table provides all information and sources you need with respect to installation steps 1) – 3). Keep in mind, you have to download either the Lazarus IDE or the stand-alone Free Pascal Compiler, not both.

Software, Version, approx. Size [MB]	Filenames, Source link	Details and remarks
Lazarus IDE (has FPC included) 1.4.4 or later N/A	lazarus-1.4.4-fpc-2.6.4-win32.exe http://www.lazarus-ide.org/index.php?page=downloads	Linux and Mac OS X versions are here: http://www.lazarus-ide.org (see Downloads).
Free Pascal Compiler (stand-alone) 3.0.0 or later 22-40	fpc-3.0.0.i386-win32.exe Windows 32 bit version fpc-3.0.0.i386-win32.cross.x86_64-win64.exe Windows 64 bit version (needs 32 bit version)	If you need the Linux, Mac OS X or other versions, check them out here: http://www.FreePascal.org (see Download).
SDL 2.0 units 1.72* (see remark) 0.1	Pascal-SDL2-for-Pascal-master.zip https://github.com/PascalGameDevelopment/SDL2-for-Pascal	On the right upper side is a button saying Download ZIP. Click on this button for the download of the latest release. *Better go with the latest availabe version (not version 1.72!) since some important bugfixes have been made lately.

Download Lazarus or the stand-alone Free Pascal Compiler (FPC)

If you have Free Pascal or the Lazarus IDE installed already, you can skip the steps 1a) and 1b).

1a)For Lazarus IDE: Download the latest version of the Lazarus IDE. It has the Free Pascal Compiler accompanied. Remark: As of today (12/02/2016) the bundle doesn’t provide the most recent Free Pascal Compiler (3.0.0) but the version before (2.6.4). The tutorial examples will work with both versions though.

1b) For Free Pascal IDE: 32 bit Windows: Download the latest stable Free Pascal compiler, version 3.0.0 or higher. 64 bit Windows: You have two choices, 1) Simple way: Go with the 32 bit version of Free Pascal. (Recommended), 2) Install the 64 bit version of Free Pascal on top of the 32 bit version of Free Pascal. In this case you need both files. Hence, you need to download both Free Pascal installers shown above.

Download SDL 2.0 and Header translation

2) Download the latest version of Tim Blume’s SDL 2.0 units, better go with the latest branch (master branch), and do not use version 1.72 since it contains some bugs. Click on “Clone or download” and then on “Download ZIP” (see arrows in image below) of the page and make sure that Branch: master (not v1.72!) is chosen at the left side (see arrow in image below). This is important for any operating system: Windows, Linux, Mac OS X.

3) Download the latest version of SDL 2.0 runtime library, version 2.0.4 or higher.

Install Lazarus or the Free Pascal Compiler

4a) For Lazarus: 32 and 64 bit Windows: Execute lazarus-1.4.4-fpc-2.6.4-win32.exe to install Lazarus for a 32 bit or 64 bit Windows system and follow the self-installer. Let the self-installer create a shortcut on your desktop.

4b) For Free Pascal IDE:32 and 64 bit Windows: Execute fpc-2.6.4.i386-win32.exe to install Free Pascal for a 32 bit or 64 bit Windows system. Let the self-installer create a shortcut on your desktop. Don’t modify any checked options during installation process. The default path is: C:FPC[Compiler version]. [Compiler version] should be 3.0.0 or higher numbers. 64 bit Windows only: After you installed the 32 bit Free Pascal, you may execute fpc-3.0.0.i386-win32.cross.x86_64-win64.exe optionally to add the 64 bit version on top.

Install SDL 2.0 and Header translation

5) Extract SDL2-2.0.4-win32-x86.zip or SDL2-2.0.4-win32-x64.zip to get the SDL runtime library. This leads to two extracted files. There is a text file and the very important SDL2.dll.

6) 32bit Windows: Copy those files (especially the SDL2.dll!) to your system32-folder, C:WINDOWSsystem32. 64bit Windows: Copy those 64bit files to your system32-folder (!), C:WINDOWSsystem32, Windows is expecting you to do this. Do not use the SysWoW64-folder (Hint: 32 bit files on 64 bit Windows go here).

If it is not possible to copy the files into this folder (or you are unsure about its location) alternativly you can copy the SDL2.dll right into the same folder where the SDL 2.0 application (.exe) is located. That is because SDL 2.0 first looks for the SDL2.dll in the folder from which it is executed and if it isn’t found there, in the corresponding system folder! Anyway, if it isn’t found anywhere, the program will raise an error.

Now you have installed Free Pascal and the SDL runtime library on your system. Finally SDL 2.0 units have to be installed.

7a) For Lazarus IDE: Extract the SDL2-for-Pascal-master.zip. The Free Pascal Compiler is located in a subfolder called “fpc”. I suggest to copy all the files to a folder with full path C:Lazarusfpc[Compiler Version]unitsSDL2. [Compiler version] should be 2.6.4 or higher numbers. Skip step 7b).
