Native

Guides originally written by James Hug. This method builds a native port for older Source engine games, such as Half-Life 2, its episodes, and Portal.

Enter these commands into Terminal, Homebrew & Xcode Command Line Tools are required:

1. Install prerequisites from Homebrew and clone Repository (added the jpeg-turbo dependency from instructions):

brew install sdl2 freetype2 fontconfig pkg-config opus libpng libedit python3 jpeg jpeg-turbo && brew cleanup
git clone --recursive https://github.com/nillerusr/source-engine && cd source-engine

2. Set pkg path:

export PKG_CONFIG_PATH="/opt/homebrew/opt/jpeg/lib/pkgconfig"

3. Configure, build and install the game into your Documents Folder:

python3 waf configure -T release --prefix='' --build-games=[game folder] && python3 waf build && python3 waf install --destdir='~/Documents/Build/[game folder]'

Valid Game Folder Names:

• cstrike (Counter-Strike Source)
• episodic (Half-Life 2: Episode 1)
• ep2 (Half-Life 2: Episode 2, can be played without python3 waf build)
• hl1 (Half-Life: Source)
• hl2
• portal
• dod (Day of Defeat: Source)
• hl2mp (Half-Life 2: Deathmatch)

4. Open your "Half-Life 2" Folder. (Portal and/or Day of Defeat Source, if you're installing those games) (Right-Click > "Browse local files" on Steam.)

5. Modify Installation Files (If you're installing multiple games, you only need to replace the files from "[game folder]/bin"):

• Delete the root and game folder "bin" directories and "hl2_osx" executable
  • Move your "bin", "[game folder]/bin" folders and "hl2_launcher" executable to your Half-Life 2 folder,
  • and rename "hl2_launcher" to "hl2_osx"

Congratulations! You (hopefully) successfully built a working Native Source Port!
