They proceeded to tell me what to download on my laptop. I repeated my question, emphasizing "ON Android". They gave me blank looks. I said, "I want to install a toolchain ON an Android device, and run it there. How do I do that?"
They had no idea.
I asked, "What if you want to compile something that requires compiling something, then using that something further down the line, like Perl?"
Again, no idea.
A platform without a native toolchain is a very awkward place to be. I stopped trying to wrap my head around it and stopped playing with Android.
