esp-open-sdk generates a complete toolchain to build native firmware applications. Further information can be found on its GitHub Project Page.

For distributions based on Debian (e.g. Ubuntu/Mint):

sudo apt-get install make unrar autoconf automake libtool gcc g++ gperf flex \
                     bison texinfo gawk ncurses-dev libexpat-dev python sed git

add libtool-bin if using Debian8/Jessie.

git clone https://github.com/pfalcon/esp-open-sdk.git
cd esp-open-sdk
make STANDALONE=y

Note: If you set STANDALONE=y, then the current Espressif SDK will be directly integrated into your toolchain. This eases the development, but makes it difficult to upgrade SDK versions later on. Set STANDALONE=n if you want to separate the SDK.

To call the generated xtensa-lx106-* binaries, you have to add the toolchain to your PATH. You can set PATH on every new terminal session:

export PATH=[your esp-open-sdk directory]/bin:$PATH

To make this change permanent add the above line to your .profile file in your home directory.

• Make sure you have javaJRE installed first.
• Go to Arduino.cc and download Latest IDE for Linux.
• Extract it wherever you want it.
• Go into that directory and open a terminal and type ./Arduino

Thats it . You can drag that shell script to the desktop if you wish. Now you follow the instructions on ESP8266/Arduino to add the ESP8266 library
