Build Astra SDK under linux

Guohiu,

Sorry you had such trouble with Shiny. We plan on removing or at least making the linkage optional based on compilation options very soon. We use Shiny to do profiling on Android platforms, and is strictly unnecessary for production usage. Additionally, we are migrating from a private git repo to github and the Shiny submodule is unfortunately still on the private host. I will work to migrate that to our public repo, but it will appear in the develop branch, which is significantly different (and better!) than the current HEAD of master on github.
