Ubuntu - Siv3D (original) (raw)

Getting Started with Siv3D Programming on Ubuntu¶

1. System Requirements¶

The development environment required for Siv3D programming on Ubuntu is as follows. The default version of GCC for your Ubuntu distribution should be used.

2. Get the Latest Siv3D Code¶

The main branch of the official OpenSiv3D repository contains the latest stable version. Clone the repository using "Code" > "Clone", or download the source code as a ZIP file ("Download ZIP").

3. Build Siv3D¶

1. Install the required dependency packages by running the commands at this link:https://github.com/Siv3D/OpenSiv3D/blob/main/.github/workflows/ubuntu.yml#L22-L23
2. Build the Siv3D library (libSiv3D.a) by running the commands at this link: https://github.com/Siv3D/OpenSiv3D/blob/main/.github/workflows/ubuntu.yml#L25-L34
3. Install Siv3D by running the commands at this link: https://github.com/Siv3D/OpenSiv3D/blob/main/.github/workflows/ubuntu.yml#L36-L39
4. Build a Siv3D app by running the commands at this link: https://github.com/Siv3D/OpenSiv3D/blob/main/.github/workflows/ubuntu.yml#L41-L50

4. Sample Program¶

The default Main.cpp code for the Linux version is a simple program that prints to standard output and exits immediately. Please replace its content with the sample code provided below. To exit the running program, press Esc or close the window.
