Access violation in ig9icd64.dll whenever I try to run my OpenGL program.

[Milan4]

I have this c++ program which uses OpenGL, and it works fine on my main pc (uses a gtx 970), but whenever I try to run it on my laptop I get this: Exception thrown at 0x00007FF974A0EAB6 (ig9icd64.dll) in Raytracer.exe: 0xC0000005: Access violation reading location 

This error is thrown at an OpenGL instruction, namely glGetProgramiv, but if i remove the line, the error gets thrown are another opengl instruction. I have read that It was a gpu driver fault, but I updated them (running a uhd 620, see attached dxdiag), but it still doesn't work. What can I do?

Edit: check out the program here: https://github.com/Milan7843/Raytracer , the error is thrown in Raytracer/src/Shader.cpp:88

At the moment  i have no recent Intel GPU handy, but my laptop dislikes your app as well.

Looks like you forgot to upload the .obj files to Github

Yep, my bad. It seems they were included in the standard gitignore made by visual studio, but I've added them now.

OK, NVIDIA GPU works now.

AMD still complains

In general i know that NVIDIA's GLSL compiler is very sloppy, but AMD and Intel are very strict.

I am no developer though, so i cannot help you in details...

Okay I've looked at the lines and asked around for bit, and it should be fixed now (also press v while running the app to actually see something 🙂

[Stefan3D]

Looks good on AMD as well

[Milan4]

woow that seems to have actually fixed it! Thank you so much for your help 😄
