Getting linker errors in dev-c++

I wanted to start working with openGL, just to try it out.
I downloaded the files nessecary, I have googled for a while to find out where to put them. I only find VC++ tutorials. I don't get those really.

I get a lot of linker errors when trying to compile my tutorial progam, any GL program for that matter:( And I just can't firgure out what to do.

I really think it has to do with these files:
glut.h
glut.lib
glut32.lib
glut.dll
glut32.dll

glut.h I got figured out. no prob there.

the .dll files have been put in windows, system and system32 dirs.

the lib files have been set as parameters in the project options.

That is about what the tutorial tells me and the rest of the web.
Why does it not work?:(

Why don't you post the error messages in this thread? By the way, your libraries should be .a, not .lib.

You have told your IDE to link against these libraries?
GCC/G++ syntax: -lglut

I have used .libs before. These just don't seem to work:(
But I will try getting them as .a files, if that is even possible.

What? IDE? Do you mean my hdd? That is a pata, not an IDE:p
Please elaborate on that a little bit, what do you mean by IDE?

I will test what damien said and update this post with the result:thup:

Edit: Here are some errors that I found on the internet. I get a few of them in mine. They are all functions that are used in the example:
Code:
[Linker error] undefined reference to `ChoosePixelFormat@8'
[Linker error] undefined reference to `SetPixelFormat@12'
[Linker error] undefined reference to `glViewport@16'
[Linker error] undefined reference to `glMatrixMode@4'
[Linker error] undefined reference to `glLoadIdentity@0'
[Linker error] undefined reference to `gluPerspective@32'
[Linker error] undefined reference to `glMatrixMode@4'
[Linker error] undefined reference to `glLoadIdentity@0'
[Linker error] undefined reference to `wglCreateContext@4'
[Linker error] undefined reference to `wglMakeCurrent@8'
[Linker error] undefined reference to `glClear@4'
[Linker error] undefined reference to `glLoadIdentity@0'
[Linker error] undefined reference to `gluLookAt@72'
[Linker error] undefined reference to `glBegin@4'
[Linker error] undefined reference to `glVertex3f@12'
[Linker error] undefined reference to `glVertex3f@12'
[Linker error] undefined reference to `glVertex3f@12'
[Linker error] undefined reference to `glEnd@0'
[Linker error] undefined reference to `SwapBuffers@4'

I can't seem to find a glut.a nor glut32.a file for it:(
I downloaded some devpackages that said to contain it, but they did not:(
Further help is needed:( I'm a complete idiot when it comes to "including" things:(

The .a files should come with your compiler. Look under "\Dev-Cpp\lib" and you should find libglut32.a and libglut.a.

IDE = Integrated Development Environment. In your case, Dev-Cpp is your IDE.

Are you linking against the opengl32, glu32 and gdi32 libraries?

Thanks damien. I found them, But I still get the same errors:(
I have linked them in the project options->parameters thingy.

Thanks for the explanation of IDE also.

+rep to both of you for the effort so far.

Are you linking against the opengl32, glu32 and gdi32 libraries?
I don't really know what you mean by that, but I got these as linkers:
../../../../../Dev-Cpp/lib/libglut.a
../../../../../Dev-Cpp/lib/libglut32.a

Those should be the only ones that I need there, but still the same errors:(

Edit: oh, and if it is to some help: This is the include: #include <glut.h>

Ok, try adding the following to linker parameters.

Code:
-lopengl32
-lgdi32
-lglu32

That kind of worked, but now it can't find opengl.dll. I think that I can figure that out myself. Thousand thanks Damien:thup: I just wish I could +rep you more:D

Edit: Can't find that either. Am I supposed to download that somewhere?

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
