Arch Linux PKGBUILDs for GOG Games

This repository provides optimized PKGBUILDs for GOG games on Arch Linux, focusing on minimal dependencies and XDG Base Directory compliance. Includes a tool to perform dependency analysis.

The xdg-laucher project originated from this repository. Rather than continuing to make customized launchers for each game to enforce user XDG directory settings, the launcher was extracted into a standalone script that should work for any application. PKGBUILDs within this repository will depend upon it as needed to ensure compliance.

Dependency Analyzer

depends.hell is a script to determine minimal runtime dependencies for games by analyzing shared libraries.

Features

• Identifies libraries loaded by a running process (--pid) or listed in a file (--file)
• Distinguishes between packaged libraries (via pacman) and local files
• Builds dependency chains with interactive confirmation for circular or otherwise ambiguous cases

Usage

depends.hell --pid <PID> | --file <input_file>

Example (Analyze Running Process)

depends.hell --pid $(pgrep -f game_executable)

Example (Analyze Library List)

depends.hell --file library_list.txt

Output

Local Libraries:
linux-vdso.so.1
/opt/some-game/included.so.x

Confirm dependency (lib-one) [y/N]? 
Confirm dependency (lib-two) [y/N]? 
Confirm dependency (lib-three) [y/N]? y
Confirmed Dependencies:
lib-zero
lib-three

As dependencies are confirmed, anything else that is included as a dependency of the one confirmed is eliminated. For instance, lets say an game needs four libraries to be installed to run: lib-zero, lib-one, lib-two, and lib-three. Further, lib-three depends on lib-two , and lib-two depends on lib-one. If it were as simple as this, the game can just depend upon lib-zero and lib-three, the script will automatically detect it and won't ask for confirmation. However, in practice--often due to circular dependencies--the user will have to confirm to include the highest level dependency.

Key Features

• Minimal Dependencies - PKGBUILDs only include dependence upon essential libraries identified by depends.hell
• XDG Compliance - Games use xdg-launch where needed to prevent home directory pollution
• Clean Installation - All files properly organized in standard Linux directories
• Arch Linux Optimization - Leverages system libraries instead of bundled versions where possible
