I am following an OpenGL tutorial from https://learnopengl.com/ (specifically https://learnopengl.com/Advanced-OpenGL/Depth-testing) and I have many errors to do with stbi. Error Log image here (Below I have also attached the complete Output tab). I have added the "#define STB_IMAGE_IMPLEMENTATION" at the top of the main.cpp file (and not in a header). If I don't use any stb_image functionalities, the project compiles and runs. I have had projects where stb_image worked fine, but all those projects that worked were x86 (or 32-bit). It seems that I can not get stb_image with x64 (or 64-bit). I know that x64 itself works since other projects without stb_image that were x64 have compiled. I have also looked back to where I downloaded the header file for stb_image and there was no option for x64 vs x86 as there was only one universal option. Here is an image of how the files are organized: File hierarchy. I will also include my main.cpp file but if you want to see a specific file let me know. I am very new to c++ since I come from java and python so any help is appreciated.
