OpenGL on Fedora 33

Installation requirements:

• GLFW: https://www.glfw.org/download.html

• GLAD: https://github.com/Dav1dde/glad or https://glad.dav1d.de

Useful links:

• How to build & install GLFW 3 and use it in a Linux project (Stack Overflow)

• Issue compiling with GLAD - C++ (Reddit)

Step 1: Install GLFW and GLAD

After installing GLFW,

1. cd <source-directory>

2. cmake -G "Unix Makefiles"

3. sudo dnf install dnf-utils glfw

4. make

5. sudo make install

After installing GLAD,

1. sudo ln -s <path/to/glad> /usr/local/include/glad
   
   # In my case,
   sudo ln -s ~/glad/include/glad /usr/local/include/glad
   

2. You will need glad.c when compiling, so put it in the project directory or wherever you can remember.

Step 2: Compile

1. Grab an example code from here and name it shaders.cpp.

2. Compile shaders.cpp with:

   g++ -std=c++11 -c shaders.cpp <path/to/glad.c>
   
   # In my case,
   g++ -std=c++11 -c shaders.cpp ~/glad/src/glad.c
   

3. Output an executable file with:

   g++ shaders.o glad.o -o shaders.exec -lGL -lglfw3 -lX11 -lpthread -ldl
   

4. Finally execute with:

   ./shaders.exec
   

   And you should see something like this:

   

Finally

If this didn't help, you should be missing more required packages and you want to google until you find an answer. I don't know anything about C/ C++, so it was kind of confusing to learn how to link stuff and whatnot, but eventually I found the answers I needed. :)

Good luck!
