Eclipse CDT -- ESP8266 -- espressif hello_world_cpp example -
i have been using arduino ide esp8266 coding, move little more powerful environment. i'm making first foray eclipse cdt environment mingw gcc toolchain.
edit -- have eclipse c arduino plugin installed: https://marketplace.eclipse.org/content/eclipse-c-ide-arduino
however, on first attempt project working, i'm running lot of issues trying compiled , linked. i've chosen hello_world_cpp example espressif sdk. i've corrected number of issues i've run into, can't seem figure out how past linking problem below. output copied below after main project code.
can guys give pointers on might start looking on problem? looks i'm missing library, life of me can't find library contains missing functions. let me know if there's further information useful.
here main cpp file:

it appears cdt running gcc host development opposed gcc cross-compiler needed generating code arduino board.
are using "vanilla" cdt, or have using arduino plug-ins eclipse.
two consider:
