Setting up GLFW with MinGW

I'm trying to learn OpenGL with GLFW, but I'm having some problems.

This is my main.cpp:

#include <GL/glfw.h>

int main()
{
    glfwInit();
    glfwSleep( 1.0 );
    glfwTerminate();
}

This is my project's folder structure:

Project
+- glfw.dll
+- main.cpp

This is where I extracted the GLFW files:

MinGW
+- include
|   +- GL
|      +- glfw.h
+- lib
   +- libglfw.a
   +- libglfwdll.a

And this is how I try to build the program:

g++ main.cpp -o main.exe -lglfwdll

And these are the errors I'm getting:

C:\Users\Dark\AppData\Local\Temp\cc0ZgTVp.o:main.cpp:(.text+0xf): undefined reference to `_glfwInit'
C:\Users\Dark\AppData\Local\Temp\cc0ZgTVp.o:main.cpp:(.text+0x25): undefined reference to `_glfwSleep'
C:\Users\Dark\AppData\Local\Temp\cc0ZgTVp.o:main.cpp:(.text+0x2a): undefined reference to `_glfwTerminate'
collect2.exe: error: ld returned 1 exit status

Am I missing something?

If you are using MinGW64 with MSYS2, install glfw library in your compiler. Open MSYS2 MINGW64 console and put:

pacman -S mingw-w64-x86_64-glfw

then compile your project using the following flags: -lglfw3 -lkernel32 -lopengl32 -lglu32

I created makefile, it's for C, but you can edit it:

all:
    gcc -I ./include ./src/*.c -L ./lib -lglfw3dll -lopengl32 -lmingw32 -lgdi32 -luser32 -lkernel32 -lglew32 -o ./bin/main

makefile

├───bin
│       glew32.dll
│       glfw3.dll
│       main.exe

├───include
│       eglew.h
│       glew.h
│       glfw3.h
│       glxew.h
│       wglew.h

│       glew32.dll
│       glew32.lib
│       glew32s.lib
│       libglfw3.a
│       libglfw3dll.a

│
└───src
        main.c

edit : this works only for windows

Download the binaries here according to your environment. 

Project
+- glfw3.dll (You can put it in System32 or SysWOW64 instead.)
+- main.cpp

MinGW
+- include
|   +- GLFW
|      +- glfw3.h
+- lib
   +- libglfw3.a
   +- libglfw3dll.a (Renamed from glfw3dll.a)

g++ -c main.cpp
g++ -o main.exe main.o -lglfw3dll -lopengl32
