Undefined symbol

Hakan Tandogdu

I can not compile a very simple PWM program on Keil
The same program is compiled on Energia
The message that I get is below:
For your information main.c is in the source file and I use C not C++.

    Energia is TI's Arduino-alike - isn't it?

    So I guess - like Arduino - it hides a lot of necessary detail from you. Like providing necessary libraries.

    Now you're moving to Keil, You're going to have to do all that yourself.

    You should probably look to TI for support in taking an Energia project into a "conventional" development environment.
    Perhaps they have a tool in their Code Composer Studio ... ?
    (rather like Atmel do for importing Arduino stuff into Atmel Studio).

    But you would have to ask TI about that.
