glew | The OpenGL Extension Wrangler Library | Build Tool library

I am following Cherno's brilliant series on OpenGL, and I have encountered a problem. I have moved on from using a vertex buffer only, to now using a vertex buffer together with an index buffer.

What I want to happen, is for my program to draw two triangles, using the given positions and indices, however when I run my program I only get a black screen. My shaders are working fine when drawing only from a vertex buffer, but introducing the index buffer makes it fail. Here is the relevant parts of code:

As the title says, I'm trying to draw a square from two triangles for class. I've tried everything I can think of but I cannot figure out why it just displays a black screen. Here is my code so far. I have the project and libraries set up correctly. I've looked over it a dozen times and can't seem to find the issue.

I've been having this same error running any kivy code I type into IntelliJ. I'm using kivy 2.0.0 and Python 3.9. Here's my code:

I have taken code for two projects. One being the code for creating a cube and another is the code for creating a pyramid. I am now trying to render both of the objects in OpenGL which I have done the problem is the objects are attached to one another. I have added some code heading towards rendering them separately, however I am now stuck where my cube is only showing 3 of the triangles used to create it and the whole pyramid shows. Yet the objects are still attached to one another. Any help or guidance?

I'm rendering this cube and it should show the front of the cube but instead it shows the back (green color). How do i solve this? I've been sitting for a couple of hours trying to fix this but nothing helped. I was trying various things like changing the order in which the triangles are rendered and it didn't help either. Thanks for any help. Here's my code.

To be clear, I've extensively tested this code and found the issue is somewhere with the code written prior to the WGL code. It's precisely in the WIN32 code. Now I think it could partially be caused by calling gluOrth2D but even then, that shouldn't be the primary cause as far I as I understand. I may figure this out myself just by messing with stuff but considering this issue (that occured in a much larger project) has taken up a lot of my time I thought it was worth posting this encase anyone else runs into the same problem. I'm hoping for an explanation as well as fix/correction.

Mac Big Sur C++ OpenGL attempting to learn quaternions from a tutorial. The gtx headers are under usr/local/include/glm. Can anyone figure out what is wrong with my header includes or header search path? Thanks.

Minimum reproducible code that fails for this issue:

I want to load some textures using glTexStorageXX(), but also fall back to glTexImageXX() if that feature isn't available to the platform.

Is there a way to check if those functions are available on a platform? I think glew.h might try to load the GL_ARB_texture_storage extensions into the same function pointer if using OpenGL 3.3, but I'm not sure how to check if it succeeded. Is it as simple as checking the function pointer, or is it more complicated?

(Also, I'm making some guesses at how glew.h works that might be wrong, it might not use function pointers and this might not be a run-time check I can make? If so, would I just... need to compile executables for different versions of OpenGL?)

Good day
