Planet Blupi development bundle

This bundle is the main repository for building the Planet Blupi game. If you are an official distribution packager, maybe you can directly use the https://github.com/blupi-games/planetblupi.git repository instead of this one but it's not the recommended way and in the case of a distribution, it needs some improvements in the CMakeLists.txt file (based on CMake).

The game is built with static linking as much as possible. The goal is to limit the linking of dynamic libraries which are not available natively on the host operating system of most users. There is only one exception on Windows about the use of the dynamic libwinpthread-1.dll library. Most dependencies are built via the CMakeLists.txt file provided here (linpng, FFmpeg, SDL2, and more with the appropriate flags). For example, FFmpeg is built only with the necessary codecs.

For Linux, the release is packaged in an AppImage. The user can download the image and adds the executable flag. Then the game is ready to play (no root needed, no dependencies to install). In the case of Darwin, it's mostly like Linux but with a .app in a DMG image. Just open the DMG and the game can be played immediatly (the user can copy the game in the /Applications directory if he wants). Only Windows is a bit different. Even if the game is standalone, the installation is provided via an NSIS installer.

Note that the DMG bundling and the NSIS building is directly provided by CMake. In the case of AppImage, it's handled by CMake too but via a custom .cmake file available in the planetblupi/cmake directory.

Prepare environment

git clone --recursive https://github.com/blupi-games/planetblupi-dev.git
cd planetblupi-dev

The source-code is written in C++, only GCC and Clang are officially supported. The clone must be recursive because the development use git submodules.

• source-code: planetblupi/
• source-assets: planetblupi-data/
• website: planetblupi-www/ (see http://www.blupi.org)

Linux

You need the usual development packages for C++ (GCC) with pkg-config and CMake.

Darwin

You need the development commandline tools provided by Apple via Xcode (Clang), pkg-config and CMake. It should be possible to use GCC via Homebrew or MacPorts.

Windows with MSYS2

In the case of Windows, it's not recommended to use MSVC because you will have some difficulties to have all dependencies. The best way is using MSYS2 with it's great package manager (pacman).

# Update your toolchain
pacman -Syuu

# Install main development packages
pacman -S --noconfirm --needed make pkg-config mingw-w64-x86_64-toolchain mingw-w64-x86_64-cmake

# Install NSIS64 for Release packaging
pacman -S mingw-w64-x86_64-nsis

How to build

On Linux and Darwin, create a Debug or Release directory.

# For debugging
mkdir Debug
cd Debug
cmake -DCMAKE_BUILD_TYPE=Debug ..
make -j

# For releasing
mkdir Release
cd Release
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j

In the case of Windows with MSYS2, it's a bit different because you need to specify the right generator (MSYS Makefiles).

# For debugging
mkdir Debug
cd Debug
cmake -G"MSYS Makefiles" -DCMAKE_BUILD_TYPE=Debug ..
make -j

# For releasing
mkdir Release
cd Release
cmake -G"MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release ..
make -j

Packaging

If you have built a release, you will find the output in the appropriate directory according to the platform.

• Linux: look at Release/linux-appimage/planetblupi.AppImage
• Darwin: look at Release/src/planetblupi_Project/planetblupi-X.Y.Z.dmg
• Windows: look at Release/src/planetblupi_Project/planetblupi-X.Y.Z.exe
