r/cpp_questions

I have been trying to compile my project for a while and realized my header file wasnt linked properly but am still not sure how to do so. i used g++ file.cpp and i did g++ -c file.cpp, which got me a .o file, unsure of what that is. The header file is in the same location as the cpp file, so i am not sure what else to do.
Here is my Code

This is me trying to compile from the Terminal

Edit I realized i was using -l wrong. You need to g++ file.cpp -l (lowercase L) raylib
