Windows 10 Anniversary Update - compile Espruino from a bash/Ubuntu console natively!

The Anniversary Update (64 bit only) has a developer mode add on that allows Ubuntu code to run in a windows subsystem.

This means Espruino can be compiled without running in a VM!

The update has not been rolled out - here are the instructions to update manually...

http://www.howtogeek.com/248177/whats-ne­w-in-windows-10s-anniversary-update/

Then turn on developer mode - reboot and add the Linux on windows system:
http://www.howtogeek.com/249966/how-to-i­nstall-and-use-the-linux-bash-shell-on-w­indows-10/

On my system - in the cmd prompt, I had this error message:
Unsupported console settings. In order to use this feature the legacy console must be disabled.

https://github.com/Microsoft/BashOnWindo­ws/issues/319
Open cmd.exe
Right click title bar -> Properties -> Uncheck Use legacy console
Click OK

Then on first run of bash.exe, the sub system is installed.

Then:

cd /mnt/c
mkdir ubuntu
cd ubuntu
sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo apt-get update
sudo apt-get install gcc-arm-none-eabi git build-essential
git clone https://github.com/espruino/Espruino.git­
cd Espruino
make

Then:

root@OFFICE-PC:/mnt/c/ubuntu/Espruino# ./espruino
Interactive mode.
Size of JsVar is now 32 bytes

hi from windows 10!

Yay!

Will try a cross compile soon!

make clean
ESPRUINO_1V3=1 RELEASE=1 make

LD espruino_1v86.113_espruino_1r3.elf
GEN espruino_1v86.113_espruino_1r3.lst
GEN espruino_1v86.113_espruino_1r3.bin
bash scripts/check_size.sh espruino_1v86.113_espruino_1r3.bin
PASS - size of 229496 is under 231424 bytes
GEN espruino_1v86.113_espruino_1r3.hex

Seems to work!

Ok. Got the Esp8266 build working on windows 10!

You need to build the SDK as a standard user. This locked up the first time, however worked after a reboot.

To build the SDK there needs:

cd /mnt/c/ubuntu/
git clone https://github.com/pfalcon/esp-open-sdk
sudo apt-get install autotools-dev autoconf
sudo apt-get install make unrar autoconf automake libtool gcc g++ gperf     flex bison texinfo gawk ncurses-dev libexpat-dev python-dev python python-serial     sed git unzip bash help2man wget bzip2
ln -s /usr/bin/aclocal-1.14 /usr/bin/aclocal-1.15
ln -s /usr/bin/automake-1.14  /usr/bin/automake-1.15
cd esp-open-sdk/
make STANDALONE=n

this takes a while to compile!

then:

wget 'http://bbs.espressif.com/download/file.­php?id=1021&sid=6e2aef8d5d8e700aca4a7b44­4c985e10' -O liblwip_536_for_ESP8266_NONOS_SDK_V1.5.0­.zip
unzip liblwip_536_for_ESP8266_NONOS_SDK_V1.5.0­.zip
cp liblwip_536.a ../esp-open-sdk/ESP8266_NONOS_SDK_V1.5.4­_16_05_20/lib

cd ../Espruino

In the Makefile this needs to be updated to: 
boot_v1.4(b1).bin -> boot_v1.5.bin

cat ./build-esp-4mb.sh


#! /bin/bash
export ESP8266_BOARD=1
export FLASH_4MB=1
export ESP8266_SDK_ROOT=/mnt/c/ubuntu/esp-open-­sdk/sdk
export PATH=$PATH:/mnt/c/ubuntu/esp-open-sdk/xt­ensa-lx106-elf/bin/
export ESPHOSTNAME=espruino:88
make $*

chmod +x ./build-esp-4mb.sh
./build-esp-4mb.sh

flash over the air from the bash shell:

./build-esp-4mb.sh wiflash

and then we have:

Does this update just let you use Bash inside the command prompt? If so, I think you could also install Git and select "Use Git and optional Unix tools from the windows command prompt" during the installation which will allow them to run this bash script just like in Linux.

No it is much more than this. It is running Ubuntu, so you can apt-get packages. What I have shown above, installs perl, python, gcc and runs them natively. This is incredibly powerful!

WilberFORCE... forcefully done! ...notches up from powerful! - Nomen est omen...

@Wilberforce I don't think the 2nd "install" in sudo apt-get install gcc-arm-none-eabi git install build-essential should be there should it?

@Ducky

Correct - I've edited the post.

This sounds great - thanks for posting up!

It'll definitely make the whole compile a lot easier for those not using Linux systems.
