I've mentioned Google's Native client before, and thought I'd take a look and see how easy it is (or not!) to get started. It's quite involved when you consider it requires these technologies: cygwin, python, subversion, git, nacl_sdk, naclports, depot_tools and that's before even writing a line of code.
So I've started working my way through these and writing them up as a How to Set Up to Develop Native Client Apps in C and C++.
After nearly a thousand words I hit a snag with a version clash in the Subversion client. Once I've resolved that, I'll carry on and get Super Snake working with Native Client.
Meanwhile if anyone else has hit this Subversion client is too old error (it's not!) and yes I have seen the error message on the Apache Subversion website, let me know how you fixed it!
