I'm facing with this issue:

Any idea?

Updating line 26 to this solves the problem: env["CXX"] = "clang++ -std=c++11 -stdlib=libc++"

Thanks, it needs to be in the settings a little lower or it will break the other platforms. I'll find some time this weekend to clean this up and make sure this project has the latest changes applied. I haven't touched it since I made the video.
