Hello GLUT
Table of Contents
Introduction
This application is an example Windows GUI application, written to demonstrate how to build freeglut applications with MinGW and MSVC. It accompanies the Using freeglut or GLUT with MinGW article on Transmission Zero.
The application demonstrates how to process key presses and how to display a basic shape in a window. It doesn't attempt to do anything fancy, as it's really just a "Hello world!" example.
Although the application targets freeglut, there's no reason why it can't use a compatible alternative GLUT implementation, e.g. Nate Robins' GLUT for Win32. Similarly, it should be possible to cross-compile the application on a non-Windows machine, compile the application to target a non-Windows machine, or build with tools other than MinGW and MSVC. However, some changes to the Makefile will likely be needed.
Building with MinGW
Before you start, changes to the Makefile may be needed. Firstly, the "INCLUDE_DIRS" and "LIB_DIRS" may need to be updated if your GLUT header files and import libraries are in a different location. Secondly, the "LDFLAGS" flags may need to be changed if you're not using freeglut. For example, if you're using GLUT for Win32, change "-lfreeglut" to "-lglut32".
To build the application on a Windows machine, open a command prompt, change to the directory containing the Makefile, and type "mingw32-make". The application should be compiled, linked, and output as "bin/HelloGLUT.exe". The appropriate GLUT DLL will either need to be in the same directory as the executable, or will need to be in a directory referenced in your "%PATH%" environment variable.
Building with MSVC
Before you start, changes to the project may be needed. Firstly, the "Include Directories" and "Library Directories" settings under "VC++ Directories", and the "Environment" setting under "Debugging" may need to be updated if your GLUT header files, import libraries, and DLLs are in a different location. Secondly, the "Additional Dependencies" under "Linker" -> "Input" may need to be changed if you're not using freeglut. For example, if you're using GLUT for Win32, change "freeglut.lib" to "glut32.lib".
To build the application in Visual Studio, select the configuration and platform from the drop-down menu, and use "Build Solution" from the "Build" menu.
The solution was created in Visual Studio 2017, but it should open in any version of Visual Studio from 2010 SP1 onwards.
Note: The project has precompiled headers disabled. This was done to ensure the project can be built with both MinGW and MSVC. There is no reason why you can't use precompiled headers with freeglut in MSVC.
