Yosemite Xcode - redefinition errors

[ackoujens]

When I use dylibs (libGLEW.1.13.0.dylib) made from the zip file from the glew website, my code runs nice and pretty but when I compile my own from this git repo, Xcode throws a shitload of redefinition errors.

Aren't these exactly the same or it there a difference?

Alright, some more details about my issue.
I was trying to get this https://github.com/andersonfreitas/opengl-boilerplate to work in Xcode.

So I just commented out every redefinition error and it seems to compile and run.
Not sure if I'm mutilating glew but here you can see what I needed to alter to make this work.

glew.zip

Hope there's a solution so this'll turn into an out of the box experience for me :D

Ah, interesting. I can reproduce this problem on Linux too.

It appears that opengl-boilerplate is trying to generate an old version of GLEW with the current version of the OpenGL specifications. Here is a workaround that works for me:

cd external/glew
git clean -xdf .
git reset --hard glew-1.13.0
cd auto/registry
git clean -xdf
git reset --hard glew-1.13.0
touch gl/specs/.dummy
cd ../..
make extensions
cd ../..

And a-la, it works again...

Thanks again code magician. I learn something new on GitHub every day it seems.
