#90601 Hello,

I'm running through setting up my WeMos D1 Mini with PlatformIO and I was following the getting started guide [1]. However after installing the esp8266 framework with `pio platform add espressif8266`, when I try and run `pio run` I get a compile error [2]. As a sanity check I installed the board in the Arduino IDE and was able to run my code. This makes me think I may need additional dependencies for platformio to run. Does anyone have any experience with this?



[1] ... uick-start

Update: The line in the log `unknown type name 'class'` stood out to me in the log. I believe for some reason the library is being compiled as C and not C++. I ran `pio run -v` to see if I could find the GCC command and this appears to be the compile command:
