Pawn

What is this?

This is a modified copy of the Pawn compiler version 3.2.3664 by Compuphase that fixes some bugs and adds a few features.

List of changes

See Known compiler bugs for the list of fixed bugs and What's new for the list of features and other notable changes.

Installation on openSUSE/SLES

There is an installation package available for openSUSE/SLES users so that you can easily install the compiler on your distribution. Please follow these steps:

Go to https://build.opensuse.org/package/show/home:mschnitzer/pawncc
On the right side, select your distribution (only if it's not disabled!)
Click "Go to download repository"
Copy the link and enter in sudo mode in your shell: zypper ar $COPIED_LINK home:mschnitzer
Again as root, type: zypper ref
Install the package with zypper in pawncc
Run pawncc in your shell to test if it's working

Building from source code

In general you will need CMake and a C compiller to build Pawn from source code.

Building on Windows

Clone this repo: git clone https://github.com/Zeex/pawn.git C:\pawn (you can use another directory instead of C:\Pawn, but make sure the path doesn't have spaces).
Install Visual Studio Community, it's free.
Install CMake.

When installing make sure to check "Add CMake to system PATH" to make your life easier.

Generate a Visual Studio project.

In Command promprt or Powershell execute the following:

cd C:\Pawn
mkdir build && cd build
cmake ..\source\compiler -G "Visual Studio 15 2017"

From the same directory as in the previous step run:
```
cmake --build . --config Release
```
or open the pawnc.sln in Visual Studio and build from there (but make sure to choose the "Release" configuration).

This will create pawnc.dll and pawncc.exe in the Release folder. You can now copy these files to your pawno folder for convenience or put them in a separate folder and configure your code editor accordingly.

Building on Linux

Use your distribution's package manager to install the required dependencies. For example, in Ubuntu you would do:

sudo apt install gcc gcc-multilib make cmake

gcc-multilib is needed for compiling a 32-bit binary (64-bit is not supported).

Now you can clone this repo and build the compiler:

git clone https://github.com/Zeex/pawn.git ~/pawn
cd ~/pawn
mkdir build && cd build
cmake ../source/compiler -DCMAKE_C_FLAGS=-m32 -DCMAKE_BUILD_TYPE=Release
make

Replace "Release" with "Debug" if you want to build a debug executable for development or submitting bugs.

Building on macOS

Install Xcode: https://developer.apple.com/xcode/
Install Command Line Tools for Xcode:

xcode-select --install

Install CMake:

brew install cmake

Now you can clone this repo and build the compiler:

git clone https://github.com/Zeex/pawn.git ~/pawn
cd ~/pawn
mkdir build && cd build
cmake ../source/compiler -DCMAKE_C_FLAGS=-m32 -DCMAKE_BUILD_TYPE=Release
make

Background

The project was originally started as a set of patches aimed to create a compiler that would be compatible with the compiler used in SA-MP (San Andreas Multiplayer).

SA-MP uses a modified version of Pawn 3.2.3664 [1] with Windows-only executables, and the developers said that they lost the source code for it which means it can't be ported to other platforms (e.g. Linux) and newly discovered bugs can't be fixed. So the main goal of the project is to re-create changes that were previously made by the devs as well as fix all known compiler bugs.

[1] It's worth noting that the version of the AMX embedded into the SA-MP server seems to be based on an older release of Pawn.
