      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Configuring OpenGL problem

6 posts in this topic

Hello,

 

That's the first time I have difficulties with setting up OpenGL. 

I just bought a new laptop with windows 8 64bit and I am using Visual Studio 2012.

I did the usual procedure with installing a 3d party lib just as I installed them on my previous PCs:

1. Download freeglut, glew, glfw, glut, sdl

2. Copy headers into "C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include"

3. Copy libs into "C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\lib"

4. Copy dll's into "C:\Windows\SysWOW64"

 

Then I downloaded the project I was developing on my other PC (was developed under windows 8 32bit if that's of any importance) and it would'n compile. The compiler threw me the following linking error:

 

Error 1 error LNK2001: unresolved external symbol __imp__glDrawArrays@12  - about 50 of these 
Error 63 error LNK2019: unresolved external symbol __imp__glClear@4 - again about 50 of these
 
The project is working perfectly on my old PC.
 
I did try to make a simple new project: click
Linked the following libraries (Properties->Linker->Input->Additional Dependencies)
opengl32.lib
glut32.lib
glu32.lib
And again it wouldn't compile, again the same linking errors:
Error 1 error LNK2019: unresolved external symbol __imp__glBegin@4 referenced in function "void __cdecl drawcube(void)" (?drawcube@@YAXXZ) P:\OpenGL_Setup\OpenGL_Setup\opengl_setup.obj
Error 2 error LNK2019: unresolved external symbol __imp__glClear@4 referenced in function "void __cdecl drawcube(void)" (?drawcube@@YAXXZ) P:\OpenGL_Setup\OpenGL_Setup\opengl_setup.obj
Error 3 error LNK2019: unresolved external symbol __imp__glClearColor@16 referenced in function _main P:\OpenGL_Setup\OpenGL_Setup\opengl_setup.obj
Error 4 error LNK2019: unresolved external symbol __imp__glColor3f@12 referenced in function "void __cdecl drawcube(void)" (?drawcube@@YAXXZ) P:\OpenGL_Setup\OpenGL_Setup\opengl_setup.obj

I don't know if I am missing something, can you give me some ideas ?

Update: I managed to run the simple projet but I cannot run my old project. It might be some problem with the platform change ? Can this be fixed ?

Which platform are you building on and are you linking the correct libraries for that platform?

 

A lot of people seem to make the mistake of switching their project over to x64 in MSVC just because they are now on a 64 bit machine. In practically all cases you will want to stay with regular x86/Win32 applications. If you do switch you will also have to get/build [b]all[/b] your libraries anew. You cannot link x86 libraries into a x64 program or the reverse. MSVC does not help there because it silently ignores all libraries for the wrong platform. This causes the annoying scenario of getting linker errors of libraries you believe you are linking.

I am building on windows 8 x64. I did download all the libraries for 64bit version. 

 

If I get it right - because previously I've built my project on 32bit system with 32bit libraries and now I am trying to use it with 64bit version libs ,that's why I am getting these linking errors.

 

So I have 2 options:
1. Replace all my x64 version libraries with x86

2. Continue using x64 libraries and make the whole project from scratch (that's not really good idea)

Right ?

OK, I've replaced the libs, now compiles and fails at runtime: "The application was unable to start correctly (0xc000007b)"

 

EDIT: Managed to run it, this time it stops responding. I think that some lib bugs it but not sure which. I have no problems running other tutorials from the internet.

Can you help me with the debugging process of that thing ?

No one can remotely help you there. Just attach the debugger and debug it as you would any other problem. If you do no know how to debug yet, you have to make it your single most important priority to learn it.

 

That said, I would advise against just turning any non-trivial x86 project into an x64 project. There is far too much that can systematically cause problems when x64-compatibility was not a design decision from the start.

Earlier this morning I found out what caused the problem. It is bug with the GLEW library.

I had to change GLFW_OPENGL_CORE_PROFILE with GLFW_OPENGL_COMPAT_PROFILE.

glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_COMPAT_PROFILE);

now it's working and everything seems OK.
