C++ Compilation

[timondurot]

Hey, how would i go about including a c++ file in one of the /apps/esp8266/ examples? i tried messing with the makefile and the projects.mk file in the bsp folder but im struggling, help please

The build environment is depdent with esp8266 rtos sdk. I didn't try it by myself but could you refer this document from ESP?

Thanks! I needed the C++ support for controlling WS2812 leds, which needs a C++ library like adafruit neopixel, neopixelbus, fastled, etc.

For anybody looking into this in the future (or you could add this to the wiki):

• renamed the main.c to main.cpp
• added CXXFLAGS += -fpermissive to my Makefile in the apps/esp8266/xxxxx_example directory (otherwise the compiler complains about unsafe castings)
• put extern "C" {} around the #include "iot_uart_cli.h" and #include "iot_cli_cmd.h"
• put extern "C" {} around app_main function
• included this library which has been patched to support the esp8266 rtos sdk: https://github.com/THKDev/NeoPixelBus_ESP8266_RTOS

Thanks for your update. I think I can update wiki page just like your suggestion.
