Build Engine Port

by Jonathon Fowler, Ken Silverman, and others

• First Release: 9 March 2003
• Email: [email protected]
• Website: http://www.jonof.id.au
• Source code: https://github.com/jonof/jfbuild
• Ken's site: http://www.advsys.net/ken

This is the source code for my port of Ken Silverman's Build game engine to make the engine functional on modern hardware and operating systems.

Minimum system requirements

• 32 or 64-bit CPU. These have been tried first-hand:
  • Intel x86, x86_64
  • PowerPC 32-bit (big-endian)
  • ARM 32-bit hard-float, 64-bit
• A modern operating system:
  • Linux, BSD, possibly other systems supported by SDL 2.0.
  • macOS 10.8+
  • Windows Vista, 7, 8/10+
• Optional: 3D acceleration with OpenGL 2.0 or OpenGL ES 2.0 capable hardware.

Compilation

Before you begin, clone this repository or unpack the source archive.

Now, based on your chosen OS and compiler:

Linux and BSD

1. Install the compiler toolchain and SDL2 development packages, e.g.
   • Debian 9: sudo apt-get install build-essential libsdl2-dev
   • FreeBSD 11: sudo pkg install gmake sdl2 pkgconf
2. Install GTK+ 3 development packages if you want launch windows and editor file choosers, e.g.
   • Debian 9: sudo apt-get install libgtk-3-dev
   • FreeBSD 11: sudo pkg install gtk3
3. Open a terminal, change into the source code directory, and compile the engine and test game with: make or gmake (BSD)
4. Assuming that was successful, run the test game with: ./kenbuild-data/game

macOS

1. Install Xcode from the Mac App Store.
2. Fetch and install the SDL 2.0 development package:
   1. Fetch SDL2-2.0.x.dmg from http://libsdl.org/download-2.0.php.
   2. Copy SDL2.framework found in the DMG file to ~/Library/Frameworks. Create the Frameworks directory if it doesn't exist on your system.
3. Open game.xcodeproj from within the JFBuild source code's xcode folder.
4. From the Product menu choose Run.

Windows using Microsoft Visual C++ 2015 (or newer) and NMAKE

1. If needed, install Visual Studio Community 2017 for free from Microsoft. Terms and conditions apply. Install at minimum these components:
   • VC++ 2015.3 v140 toolset for desktop (x86,x64)
   • Windows Universal CRT SDK
   • Windows 8.1 SDK
2. Open the command-line build prompt. e.g. VS2015 x64 Native Tools Command Prompt or VS2015 x86 Native Tools Command Prompt.
3. Change into the JFBuild source code folder, then compile the engine and test game with: nmake /f Makefile.msvc
4. Assuming success, run the test game with: kenbuild-data\game

Compilation options

Some engine features may be enabled or disabled at compile time. These can be passed to the MAKE tool, or written to a Makefile.user (Makefile.msvcuser for MSVC) file in the source directory.

These options are available:

• RELEASE=1 – build with optimisations for release.
• RELEASE=0 – build for debugging.
• USE_POLYMOST=1 – enable the true 3D renderer.
• USE_POLYMOST=0 – disable the true 3D renderer.
• USE_OPENGL=1 – enable use of OpenGL 2.0 acceleration.
• USE_OPENGL=USE_GL2 – enable use of OpenGL 2.0 acceleration. (GCC/clang syntax.)
• USE_OPENGL=USE_GLES2 – enable use of OpenGL ES 2.0 acceleration. (GCC/clang syntax.)
• USE_OPENGL=0 – disable use of OpenGL acceleration.
• WITHOUT_GTK=1 – disable use of GTK+ to provide launch windows and load/save file choosers.

Test game configuration

Settings for the KenBuild test game and its editor can be found in these locations depending on your operating system:

• Windows 7, 8/10: C:\Users\xxx\AppData\Local\KenBuild
• macOS: /Users/xxx/Library/Application Support/KenBuild
• Linux: ~/.kenbuild

Credits and Thanks

• Ken Silverman for his patience, help, and guidance.
• Ryan Gordon for inspiring me to try and match his port.
• Pär Karlsson for his contributions.

Enjoy!
