Scope problems(?) with PlatformIO

Question

I have been looking at other development platforms for working on Atmel (Arduino/ATTiny) and Espressif (ESP8266) based devices. Most recently, I installed PlatformIO. But I'm having trouble with what appears to be recognition of global scope. Not sure...

I have a header file that includes a typedef for a configuration struct:

typedef struct {
        char idPrefix[8];
        char defPass[16];
        char targetSSID[32];
        char targetPass[64];
        uint8_t beepInRange;
        uint8_t beepOutofRange;
} devConfig;

I want to assign a config variable in my ino file:

devConfig myConfig;

but when i try to access it in my setup or loop, e.g.:

void setup() {
  strncpy(myConfig.defPass, "somepass", 16);
}

It spits out the "error: 'myConfig' was not declared in this scope" when I try to platform run

Does this thing not support global variables in the same way as arduino? What am I doing wrong? Any help is appreciated.

I think you must have forgotten to add #include "Arduino.h" header file in the main code. Also, do note that Platform IO compiles cpp files not ino file.

main.cpp

// Without Arduino.h this code will not compile
#include "Arduino.h"
#include "demo.h"

devConfig myConfig;

void setup() {
  strncpy(myConfig.defPass, "somepass", 16);
}

void loop() {

}

demo.h

typedef struct {
        char idPrefix[8];
        char defPass[16];
        char targetSSID[32];
        char targetPass[64];
        uint8_t beepInRange;
        uint8_t beepOutofRange;
} devConfig;
