GLFW/glfw3.h included failed

I just start learning opengl and I started with GLFW library. And I download the "Windows pre-compiled binaries" from http://www.glfw.org/download.html. Then I unzip my file into C:\GLFW

And now I have a problem when compiling my code. I use mingw in command line, like

gcc main.c -IC:\GLFW\include\GLFW -LC:\GLFW\lib-mingw -lglfw3 -lglfw3dll -lopengl32 -lgdi32

It always show "fatal error: GLFW/glfw3.h: No such file or directory"

but if I change #include <GLFW/glfw3.h> into just #include <glfw3.h> in my code,

it compiles successfully.

But every tutorial shows me the former. Why?

If I put the header file and lib file into mingw's searching path, is there any different?

It is because you include directly to C:\GLFW\include\GLFW, so there is no GLFW folder in this directory. If you want to use #include <GLFW/glfw3.h>, you will want to use this path instead C:\GLFW\include.

To answer to your two questions:

  1. The include path is very relative to you. What do you prefer, #include <GLFW/glfw3.h> or #include <glfw3.h>?
  2. You can put the lib and header in the mingw's path, but you have to remember that you will still need to enter the good path (#include <GLFW/glfw3.h> if you put it in the folder). I would not recommend this method, since I prefer to make an include and lib folder into my project directory. If you want to do more research: http://www.mingw.org/wiki/includepathhowto.
