Build Instructions for Linux

Note

This page applies to the in-development new build system. For current build instructions, see here.

Debian-based Build Instructions

1. Install dependencies

In a terminal window, install ares dependencies using apt:

First, install build system dependencies:
```
sudo apt install build-essential cmake ninja-build pkg-config curl ccache git
```
Compiling with clang is optional, but generally recommended:
```
sudo apt install clang
```
Next, install required ares dependencies:
```
sudo apt install \
    libgtk-3-dev \
    libcanberra-gtk-module \
    libgl-dev
```
Lastly, install optional dependencies (at least one audio driver is recommended):
```
sudo apt install \
    libasound2-dev \
    libao-dev \
    libopenal-dev \
    libsdl2-dev \
    libpulse-dev
```
Installing librashader (via Open Build Service) is also recommended but not required.

2. Get the source code

In a terminal window, navigate to a directory where you would like to build ares.
Clone the ares repository and change into its directory:

git clone https://github.com/ares-emulator/ares
cd ares

3. Build ares

First, generate a build environment:

mkdir build && cd build
cmake .. -G Ninja

During the above generation step, you can optionally configure ares in a number of ways. See the Build Options page for a full list of configuration options.

Next, build the project:

cmake --build .

With ares built, you may run it from the staging directory:

./rundir/bin/ares

If you want to install ares to another location, you may also optionally do so with CMake:

cmake --install . --prefix </your/chosen/prefix>

Red-Hat based (Fedora, etc.)

1. Install dependencies

In a terminal window, install ares dependencies using dnf:

Build system dependencies:
```
sudo dnf install cmake ninja-build pkg-config curl ccache git
```
Compiling with clang is optional, but generally recommended:
```
sudo dnf install clang
```
Next, install required ares dependencies:
```
sudo dnf install \
    gtk3-devel \
    libx11-devel \
    libXrandr-devel \
    mesa-libGL-devel \
```
Lastly, install optional dependencies (at least one audio driver is recommended):
```
sudo dnf install \
    openal-soft-devel \
    alsa-lib-devel \
    sdl2-devel \
    pulseaudio-libs-devel
```
Installing librashader (via Open Build Service) is also recommended but not required.

2. Get the source code

In a terminal window, navigate to a directory where you would like to build ares.
Clone the ares repository and change into its directory:

git clone https://github.com/ares-emulator/ares
cd ares

3. Build ares

First, generate a build environment:

mkdir build && cd build
cmake .. -G Ninja

During the above generation step, you can optionally configure ares in a number of ways. See the Build Options page for a full list of configuration options.

Next, build the project:

cmake --build .

With ares built, you may run it from the staging directory:

./rundir/bin/ares

If you want to install ares to another location, you may also optionally do so with CMake:

cmake --install . --prefix </your/chosen/prefix>

Other

Prerequisites

Git
CMake 3.28 or higher
A compiler toolchain such as clang or gcc

ares requires development versions of the following packages in order to build:

X11
libGL
GTK3 (gtk+-3.0)

Recommended development packages include:

librashader
SDL2

You may also configure with development packages for other audio drivers:

OpenAL
AO
ALSA
PulseAudio

Optional but recommended build tools include:

Ninja
clang
Ccache

Configuration

First, clone the ares repository:

git clone https://github.com/ares-emulator/ares
cd ares

Building ares with clang and Ninja is recommended:

mkdir build && cd build
cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -G "Ninja Multi-Config"

The generation step will report what features are enabled and disabled according to the libraries found on your system. Next, build ares:

cmake --build .

After building, products can be found in the rundir folder. ares can be run from this location, or the rundir can be relocated. ares can also be installed:

cmake --install . --prefix <your install prefix>

For further configuration options, see the Build Options page.

Staging Directory Structure

The build staging directory uses a standard prefix structure described below. Since ares does not ship any libraries, ares can be run freely from this staging directory, and the rundir can also be relocated. It is still, however, recommended to use CMake's --install command to install ares in a particular location. Installs and staging follow CMake GNUInstallDirs conventions for directory naming.

If you wish to not install slang-shaders underneath the ares data directory, pass -DARES_BUNDLE_SHADERS=NO during build configuration.
