Makefile to build arduino code for ESP8266 under linux (tested on debian X64). Based on Martin Oldfield arduino makefile : http://www.mjoldfield.com/atelier/2009/02/arduino-cli.html

05/09/2016 :

• update to esp8266-2.2.0
• new OTA params : OTA_IP OTA_PORT OTA_AUTH (see example)

03/08/2016 :

• Handle subdirectories of core uniformly : pull request from surr. Thank you

02/29/2016

• Cygwin support (from intrepidor not tested)
• update to esp8266-2.1.0
• user can install specific libraries in libraries dir

02/21/2016 :

• fix mkspiffs install

02/18/2016 :

• new x86 and x64 linux install
• cleanup

08/12/2015 :

• add install script for 32 bit linux
• update to esp8266-2.0.0-rc2

04/11/2015 :

• use zip file from official link (http://arduino.esp8266.com/staging/package_esp8266com_index.json)
• ESP8266 git submodule removed
• remove $(ARDUINO_CORE)/variants/$(VARIANT) to include path (not needed)

08/10/2015 :

• add $(ARDUINO_CORE)/variants/$(VARIANT) to include path for nodemcuv2

29/09/2015 :

• fix README for third party tools installation
• move post-installation out of the makefile

23/09/2015 :

• working dependencies
• multiple ino files allowed
• core & spiffs objects build in their own directories
• autodetect system and user libs used by the sketch
• Makefile renamed to esp8266Arduino.mk

• Clone this repository : git clone https://github.com/thunderace/Esp8266-Arduino-Makefile.git
• Install third party tools : for 64 bits linux cd Esp8266-Arduino-Makefile && chmod+x install-x86_64-pc-linux-gnu.sh && ./install-x86_64-pc-linux-gnu.sh && cd .. for 32 bits linux : cd Esp8266-Arduino-Makefile && chmod+x install-i686-pc-linux-gnu.sh && ./install-i686-pc-linux-gnu.sh && cd ..
• In your sketch directory place a Makefile that defines anything that is project specific and put this line at the end include /path_to_Esp8266-Arduino-Makefile_directory/esp8266Arduino.mk (see example)
• make upload should build your sketch and upload it...

#dependencies

• this project install the lastest stable esp8266/Arduino repository (2.0.0) and the last stagging esptool and xtensa-lx106 toolchain

• build user libs in their own directory to avoid problems with multiple files with same name.
