Gitpod Sample - make fail

[fredkwok-it]

While I am playing around the Gitpod sample - https://pthom-imguimanual-ddodw9hmo84.ws-us114.gitpod.io/

When I did the first make, I got follow error. Is it something outdated on Gitpod repository?

Sorry I do not maintain the gitpod example anymore. I should remove it from the repository.

But you can comment out the lines that fail, it should work. This is due to the fact that the SDL version shipped with emscripten is out of date.
