Join Pablo Colapinto for an in-depth discussion in this video Creating a context and a window, part of Learning OpenGL.
- Let's take a look at using GLFW to create a window.…We're gonna include the same header files as before…and initialize GLFW and create a GLFW window…as we did in the last lesson.…We'll also make it our current context.…Here's some new code.…On the lines 45 to 57 we define our main loop.…This is the draw loop that's going to be…rendered once per frame.…The default is 60 frames per second.…
We're going to execute this code…while the window is open.…GLFW window should close is a method that takes in a…window and returns whether we want to close the window.…If we don't want to close the window,…we're gonna execute this code.…It's a bit of double negative but it works.…GL viewport is the rectangular region of the window…in which we would like to draw.…GL viewports takes as parameters the…x and y-coordinate of the top left hand…part of the rectangular region we'd like to draw.…
In this case zero zero,…referring to the left top hand corner of our window.…And a width and height of the rectangular…region in which we'd like to draw.…

Q: Why am I getting errors saying I don’t have GLEW installed when I try to create the Xcode projects with Cmake?
1) Download, Install, and Run Xcode
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
brew install glew
./bootstrap && make && make install
brew install cmake
