RT: Getting Started With GLUT/OpenGL

[Anonymous]

I also am having link problems with the symbols 'glutInitWithExit@12', 'glutCreateWindowWithExit@8' and
'glutCreateMenuWithExit@8'.

These symbols appear in the library file glut32.lib, but NOT in the library file libglut32.a. 

I have checked the downloads for this file many times, from different sites, and have not been able to locate a library file for the format 'libXXXX.a' that contains the desired symbols.

Do I link in with the file glut32.lib?

If so, how do I do that if it is not in the required format?

[Wayne Keen]

Could you post a simple as possible example program that shows the effect you are seeing?

Thanks in advance.

[Wayne Keen]

Simple.  You did NOT link the libraries.  There are no commands to be seen of the form

-lglut32

in your compile log.

Take a few minutes to look at the section in the thread "The Forum FAQ - Please Read First" covering the compile log, headers and libraries.  It talks about the hows in some length.

Wayne

[Wayne Keen]

By the way, copying from the first link is this thread, which presents my example, note that I said:

Compiling this as a simple file, I went to Tools:Compiler Options:Compiler:Add these Commands To The Linker Command Line

-lglut32 -lopengl32

And I go a compile log that looks like this:

Note how the link commands show up in my log.  One way or another, your link commands did not happen.

Wayne

[Wayne Keen]

Perhaps you made one of my favorite mistakes (its really hard to pick a favorite I make so darn many mistakes)....did you check the box next to the link options after you entered them.

I forget from time to time, the sound of a hard slap to the head clearly audible in the next county.

Wayne

[Nobody/Anonymous]

Well it works now you were right it was the check box but I think I was confused. I had the add these commands to the linker checked. But when I checked the add the following when calling the compiler box it worked.

Thanks a ton.

[Nobody/Anonymous]

Since we arn't spost to compile as a project.. How do you remove that icky dos window?

[Nobody/Anonymous]

You can compile as a project, I just did my example that way to keep it as simple as possible. (In deference to ME ;-)

I know a couple if the folks here have answered that question before....a search should bring them up.  I am on my way out the door to get my boy, I'll check back later and see if you found it...

Wayne

[Nobody/Anonymous]

I decided to use the 2nd example and that works!

Where can I learn more about this? I like Virtual Reality! :p

[Nobody/Anonymous]

Nevermind, I found one at http://www.lighthouse3d.com/opengl/glut/

[Nobody/Anonymous]

I just want to add something i discovered recently:
All sorts of compiler errors may happen if you have a "glut.h" header that is not suited to MinGW.
For example, a glut.h made for Visual Studio may not add __stdcall to function prototypes, because those #ifdefs do not recognize MinGW. What happens next is a mismatch between the function names in your ".o" and the library (one with and the other without "...@number", or vice-versa). Also, there are other hacks int glut.h that interfere with mingw handling of libraries, such as the ATEXIT_HACK.

Having explained that, i really want to know:
***Why MinGW comes with libglut32.a but not with glut.h???***
--mac

[Nobody/Anonymous]

just follow instructions on the OpenGL compiler setup but additonal in your main.cpp add this above everything else (includes)

#define GLUT_DISABLE_ATEXIT_HACK

also make sure you have #include <windows.h> above the line #include <glut.h>

this should do the trick..

Hi All,

My first post here.  The GLUT topic caught my attention, it relates closely to what I am trying to do now, which is to  port a finite element gui called cgx from linux to win.  Have spent more than a week messing around with cygwin, couldn't get the GL/GLUT thing working there, found DevCpp, decided to try.  Btw, DevCpp seems very comfortable, reminiscent, not surprisingly, of my many hours spent with Delphi 1 and 5. 
  Those many hours did not impart any awareness of GL issues or techniques.

I was able to follow the above instructions well enough to get drwayne's sample file linked without errors.  A white cube -- it's not supposed to be grabbable, is it?

Light Knight's sample would not link for me.  Also, some of the GL sample files would not compile.  I thought this msg would be a long one -- I was even going to give a complete breakdown of glutming.zip contents and file by file destination.  But now it's not necessary, because scolling up I noticed the 'lglu32' linker directive, which I had not noticed before.  After adding that, the file linked like a charm.

So nothing left to add except big thanks for getting me started.  Now I can start to get down to details in my project.

Re-read my examples.  Your log shows that you did not link any of the proper libraries, which accounts for your linker errors.

No link commands whatsoever.  Note that if you use a project, you have to set up your link commands in the project options, not in the tools:compiler options (Note my first example did not use a project)

Also note that storing your projects in paths with spaces in them is a bad idea.

An OpenGLUT DevPak has been added to the devpak
repository:
http://devpaks.org/show.php?devpak=91

The OpenGLUT replacement library for GLUT is becoming
stable for both Unix and Win32. Converting a GLUT-based
program to OpenGLUT is a matter of:

1) Installing the OpenGLUT devpak
2) Changing #include<GL/glut.h> to #include <GL/openglut.h>
3) Linking against -lopenglut instead of -lglut
4) Defining the symbol -DOPENGLUT_STATIC to the compiler
5) Recompiling the application

We would appeciate feedback from the Dev-C++ community,
especially in relation to any problems or incompatibilities.
This is our first release that includes a DevPak and we're
interested to see your response.

Thanks for any help ^_^

[Wayne Keen]

One mostly unrelated question. You are compiling this as a windows project. Why are you doing that? Its a console program.

Note also that the local directory is not where the dll goes. It has to go in a path where the compiler looks for executable code. By default - Unix ancestry code does not look for such code in the current directory. It needs to go in either the Dev bin directory of your windows system32 directory.

Finally, you really do not want to install Dev in a directory with spaces in it, as you did. It willbite you eventually. Hard.

Do a search on the distinctive error name

gxx_personality_vo

I think you will find what you seek.

I use the version of GLUT found at DevPaks.org (it's one of the webupdate sites by the way). It's the latest (really old still) version, and it's a static mingw library, instead of ptrpck's converted MS dynamic library.

It might work better for you than the "glutming" version...
