Introduction

This repository contains source code ported from original Visual Studio 2010 projects into gcc and make buildable format.

Luabind was updated to 0.9.1 with some patches for newer boost libraries applied.

Build environment

All code samples build on Windows XP SP3 32-bit and Windows 7 64-bit without errors. Lots of compiler warnings though.

This code won't compile on Linux or Mac, since win32 api calls are used. Porting to gtk+ or Qt to handle graphics and mouse and keyboard input wouldn't be much of a deal, but I don't have any enthusiasm left right now.

Steps

Those instructions are for Windows XP. If you are using anything modern install newer versions of Git and gcc. Don't install 32 bit versions of Git on 64 bit Windows and don't mix 32 bit and 64 bit libraries on your system.

a) Install Git for Windows (Git-2.10.0-32-bit) Download location: https://github.com/git-for-windows/git/releases/tag/v2.10.0.windows.1

b) Install TDM-GCC compiler (tdm-gcc-5.1.0-3) Download location: https://sourceforge.net/projects/tdm-gcc/files/TDM-GCC%20Installer/

  1. Deselect 'Check for updated ...' option if using the offline installer
  2. (Optional) Add 'OpenMP' during install to get easy multithreading support
  3. After install go to C:\TDM-GCC-32\bin and make copies of those two files (select the file, press CTRL+C and then CTRL+V): mingw32-make and gdb32
  4. Rename copies to simply 'make' and 'gdb' respectively.

c) Compile Lua 5.1 (lua-5.1.5.tar) Download location: https://www.lua.org/versions.html#5.1

  1. Unpack the archive, open the folder with 'Git Bash Here' (by right clicking)
  2. Compile with 'make mingw local'
  3. Copy the following files or folder contents into TDM-GCC-32 directory:
Source Destination
lua-5.1.5\lib\liblua.a TDM-GCC-32\lib
lua-5.1.5\bin TDM-GCC-32\bin
lua-5.1.5\src\lua51.dll TDM-GCC-32\bin
lua-5.1.5\include TDM-GCC-32\include

d) Download boost 1.57 and unpack files somewhere (say C:\Devtools) Download location: https://www.boost.org/users/history/version_1_57_0.html

e) Install boost-build

  1. Open windows command crompt (Start > Programs > Accessories > command prompt, not Git Bash) and cd to C:\Devtools\boost_1_57_0\tools\build
  2. Run bootstrap.bat gcc
  3. Run b2 install --prefix="C:\Devtools\boost-build" toolset=gcc
  4. Add C:\Devtools\boost-build\bin to Windows PATH: Right click on 'My Computer', go to 'Advanced > Environment Variables' Add new 'PATH' variable to 'User variables' if necessary; append 'C:\Devtools\boost-build\bin' to its values

f) Compile and install boost 1.57

  1. Open new (needs to re-read PATH) windows command prompt and go to C:\Devtools\boost_1_57_0
  2. Run this:
  3. bootstrap.bat gcc
  4. b2 --build-dir="C:\Devtools\boost_1_57_0\build" --prefix="C:\Devtools\boost" toolset=gcc install
  5. (Optional) This will expose boost headers and make linking simpler, but will also shadow all other versions of boost on your machine. Copy the following files or folders into TDM-GCC-32 directory:
Source Destination
C:\Devtools\boost\include\boost-1_57\boost TDM-GCC-32\include
C:\Devtools\boost\lib TDM-GCC-32\lib

Now you can build code like this (second example from 'Getting started'):

$ g++ main.cpp -lboost_regex-mgw51-mt-1_57

f) Build Luabind

  1. Open new windows command prompt and go to luabind-0.9.1 directory
  2. Export required variables:

set BOOST_ROOT="C:\Devtools\boost\include\boost-1_57"

set LUA_PATH=C:\TDM-GCC-32

  1. Build luabind with: bjam stage toolset=gcc release
  2. Copy the following files or folders into TDM-GCC-32 directory:
Source Destination
luabind-0.9.1\luabind TDM-GCC-32\include
luabind-0.9.1\stage\libluabind.dll.a TDM-GCC-32\lib
luabind-0.9.1\stage\libluabind.dll TDM-GCC-32\bin

g) Now you can build any project by executing 'make' in Git Bash terminal.

MINGW64 /PGAIE/Buckland_Chapter3-Steering Behaviors
$ make
Building main.o
...
Building all
g++ ... -o Steering.exe

Note. Run compiled applications in windows command prompt or just double click them to run. Don't use Git terminal.

h) Code editor recommendations:

  1. Visual Studio Code
  2. Qt Creator (3.6.1 works fine with this setup)
  3. Eclipse Cevelop
  4. Notepad++
