Native ARM build from leaked source

These instructions are heavily based on guides written by James Hug. This method can be used to build native ARM macOS ports of Half-Life, Half-Life 2, Half-Life 2: Episode 1 & 2, Portal, Counter-Strike: Source etc. as long as the necessary game files from Steam have been copied into the correct folder.

Enter these commands into a Terminal window:

1. Install Homebrew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

On Apple Silicon Macs: remember to set the path, modify this command with your username:

(echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> /Users/$(whoami)/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

2. If Xcode Command Line Tools does not install, then install it manually:

xcode-select --install

3. Install required packages from Homebrew (added the jpeg-turbo dependency from instructions)

brew doctor
brew cleanup
brew install sdl2 freetype2 fontconfig pkg-config opus libpng libedit python3 jpeg jpeg-turbo

4. Clone the Source Engine GitHub repository

git clone --recursive https://github.com/nillerusr/source-engine
cd source-engine

5. (this is step was not needed when building HL2 on 1st July 2023) The location of StubSteamAPI was recently moved on 23rd May 2023, so this has to be put into the correct place for the build scripts to work:

1. Rename /stub_steam/ to /StubSteamAPI/
2. Move /StubSteamAPI/ into the /thirdparty/ folder.

6. Set pkg path:

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

7. Configure game builds:

• Half-Life 2:
  • python3 waf configure -T release --64bits --prefix= --build-games=hl2
• Half-Life 2 Episodes:
  • python3 waf configure -T release --64bits --prefix= --build-games=episodic
• Portal:
  • python3 waf configure -T release --64bits --prefix= --build-games=portal
• Counter-Strike: Source:
  • python3 waf configure -T release --64bits --prefix= --build-games=cstrike

8. Build the game:

python3 waf build

9. Create Build folder Install build into directory, this can be located anywhere ideally append with hl2, episodic, portal, cstrike etc.

python3 waf install --destdir='~/Documents/Build folder/hl2'

10. Open Build folder in new Finder window.

11. Open Mac version of Steam and install games e.g Half-Life 2, Episode 1, Episode 2, Portal, Counter-Strike: Source etc. these game files I will refer to as the Steam folder.

12. Open Steam folder in Finder: right-click on game in Steam library, go to Manage and Browse local files. Alternatively navigate to ~/Library/Application Support/Steam/steamapps/common/

13. In the Steam folder:

• Delete Steam folder/bin/ folder.
• Copy/move Build folder/bin/ folder into Steam folder/ replacing the previous Steam folder/bin/ folder.

14. In the Steam folder:

• Delete hl2_osx
• Copy/move from Build folder Build folder/hl2_launcher
• Rename the hl2_launcher into hl2_osx

15. In the Steam folder:

• Navigate inside 'game' folder (e.g. /hl2/ or /episodic/ or /portal/ or /cstrike/)
• Delete the bin subfolder (e.g. Steam folder/hl2/bin/)
• From the Build folder go to game folder (e.g. Build folder/hl2/) and move/copy from the Build folder to the Steam folder into the game (e.g. Steam folder/hl2/)

16. Now the respective game can be launched from within Steam.

17. Other parameters:

• cstrike (Counter-Strike: Source) - in addition tot he above instructions, also copy the Steam folder/hl2/ and put it in the root of the Steam folder so that the game will launch.
• tf (Team Fortress Classic)
• dod (Day of Defeat)
• hl2mp (Half-Life 2: Deathmatch)
