Join Pablo Colapinto for an in-depth discussion in this video Cleaning up the code: Make a shader struct, part of Learning OpenGL.
- To prepare for the lessons that follow,…let's take a look at the way that we can…clean up the code so that we don't have…to include our shader functions…at the top of the screen every time.…Here in our "include" folder there's a gl_shader.hpp file…where I've put all of our create shader,…shader source, compile shader, etcetera code.…This also takes care of checking…that the compilation of the shader…was complete and accurate, and also checks…for linking and validates the program…to make sure that everything is OK.…
From now on, we're just going to…include gl_shader.hpp at the top of our files.…Also, gl_macros.hpp contains the GenVertexArrays…and BindVertexArrays macros that we've been using.…And the GLSL stringification command that allows us…to write shader code directly in our CPP files.…So here we've seen a couple quick ways…to encapsulate some of the code…that's becoming more complicated,…so we can include these hpp files…at the beginning of our source code from now on.…

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
cd Exercise Filesmkdir xcodecd xcodecmake -G "Xcode" ..
