I just updated this page to add the Archlinux and correct some mistakes.

First step:

• Install the SDK

The SDK I used here is https://github.com/pfalcon/esp-open-sdk

The machine I used first was a Debian Sid. I did follow the same steps (except the package install part) and it worked exactly the same.

Change regarding their README, unrar is unrar-free

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

$ git clone --recursive https://github.com/pfalcon/esp-open-sdk.git

I want a the more open version possible, so we separate the closed SDK from the open parts.

$ make STANDALONE=n

At this point I would recommend that you keep a backup of this whole toolchain. It is downloading a lot of stuff and if one gets abandonned, you will never be able to use this toolchain anymore in some years.

To use it:

$ export PATH=/home/$USER/Programmes/ESP/esp-open-sdk/xtensa-lx106-elf/bin:$PATH

To link with the proprietary SDK if needed:

xtensa-lx106-elf-gcc -I/home/$USER/Programmes/ESP/esp-open-sdk/sdk/include -L/home/$USER/Programmes/ESP/esp-open-sdk/sdk/lib
