The present document compiles a list of guidelines, recommendations, and expectations around the topic of compiling C and C++ code against the Core SDK.

That directory contains a complete sysroot and may be used with any tool that
accepts a --sysroot flag.
Prebuilts

Debug symbols
Debug symbols for all prebuilts are available under //.build-id, which follows
a standard convention.
Compilation parameters
- C++ sources must be compatible with C++17.
