OpenGL with C++ 1: Intro and Setup

[@brown.paperbag]

omg i started taking coding seriously about 2 weeks ago, taught myself c++ and had been trying to learn openGL, but have been at a road block for so long trying to just set everything up. all the resources i found were either in visual studio not vs code, didn’t work for me, or just confused me even more. i got to the point where i had a window, and some stuff but finding this serious is truly a god send, it’s like exactly what i’ve been looking for

Welcome!

[@cryptigo]

Learning OpenGL as a new programer is really bold and impressive

[@ducksreviewtech3396]

I just want to say this is the only tutorial that has worked for me. Thanks.

[@MeowMeowRanger]

Concise and considering (from the perspective of beginner). Greatest openGL tutorial on youtube.

[@UhGoomba]

your channel has everything I want to learn, in the right ways

Incase you still get the error for glfw library not found , edit the cmake and add this "find_package(glfw3 3.3 REQUIRED)" in between "target_include_directories(Mathematics PRIVATE lib) target_link_libraries(Mathematics glfw)"

[@hi_8983]

Windows user here. I installed mingw-w64 via MSYS2, added it to PATH, and used its pacman interface to install gcc, gdb, cmake, and glfw. I of course still needed the glfw3, glad, and khr headers as shown in the video, but in terms of binaries, everything worked immediately. I did pass "glfw3" instead of "glfw" as the argument to target_link_libraries, however. Hope this is helpful!

[@GetIntoGameDev]

Thanks, very descriptive!

I have an error when following at 18:11, "GLFW/glfw3.h: No such file or directory" coming from gcc. As another thing, my glfw doesn't have any folders with "lib" in the name. Can you help? EDIT: FYI I am using Windows

[@GetIntoGameDev]

Are you following this tutorial code? In this tutorial I use cmake, in which case it should absolutely be able to locate the glfw header, provided the folder structure has been set up properly. I think in the github repo I moved dependencies outside to reduce repeated code. On the other hand, windows may have trouble finding the lib files, I’ve got a video somewhere on my channel where I go through including glfw source code directly using git submodule. Glfw doesn’t have lib? Sometimes it’s called bin instead, or actually needs to be compiled from source using cmake. Also, I believe there’s a regular glfw release and a “developer” release. The developer one is what you want. Hope that helps!

[@Madz-p4l]

absolutely love your videos 🤍

[@GetIntoGameDev]

Thankyou!

I'm here to say that using batch files on Windows will work. I did this entire tutorial because CMake wasn't working. Below is my `build.bat` file if you want to copy. @echo off if not exist dist mkdir dist g++ -Idependencies -Llib -o dist\YourProgramName.exe src\*.cpp src\glad.c -lglfw3 -lgdi32 -lopengl32 .\dist\YourProgramName.exe Note that some things should be changed based on your actual project.

[build] LINK : fatal error LNK1104: cannot open file 'glfw.lib'

[@pankajsadhukhan2686]

Hello, I'm setting up this in my windows. I have done all the steps. But at the end when I tried to run .cpp file it gives me error that "-lglfw cannot find". All other libraries linking are working fine. but I can't able to resolve this error. What to do?

[@GetIntoGameDev]

Are you including the lib files and instructing visual studio to look for them? There’s a good amount of info online on how to set this up, eg. learnopengl.com

[@babilman2337]

Will you continue thisnseries anda what Will you make.good luck on the making of tuts tho

[@GetIntoGameDev]

Yes it's continuing! I'm thinking one video per week or something like that, for the final project I'll be making some sort of first person shooter.

I'm using Debian 12 with gcc amd64, and get error as: [build] /usr/bin/ld: cannot find -lglfw: No such file or directory. FIX: sudo apt-get install libglfw3-dev

[@GetIntoGameDev]

Excellent! Glad you fixed it 🙂

[@mrstanlez]

@@GetIntoGameDev Thank you. Any future thoughts about new 2D game series with OpenGL ? Will be very helpful.

Hi, First of all thanks a lot for your videos. If this course covers image warping using opengl. I recently started opengl in my project my work is for using image warping using open gl for AR HUD.

cannot find -lglfw: No such file or directory every time! help!

[@GetIntoGameDev]

which system are you in? Did you try running the finished code in the github repo?

@@raze3055 Have you tried editing CMakeLists.txt file to insert after the target_include_directories statement the following (assuming CMake version >= 3.13): target_link_directories(hello_window PRIVATE dependencies/lib ) and changed glfw to glfw3 in the subsequent target_link_libraries statement?

[@JakubSK]

This is why no one uses C++, it's super annoying with the libraries. It's just error after error after error... to infinity...

skill issue my friend. after you've getting hang of it, it will not be a problem 😅
