make: esptool2: Command not found

I'm trying to build the esp8266/Basic_Blink example but I'm getting the following error:

# Generating image...
make: esptool2: Command not found
make: *** [out/build/app.out] Error 127

I'm running a fresh vagrant provisioned with Sming as per the project wiki and this article

I've patched my provision.sh file to pull in esptools2 as per issue #12

cd ~/dev
if [ ! -e ~/dev/raburton-esp8266 ]; then
  git clone https://github.com/raburton/esp8266 raburton-esp8266
fi

if [ ! -e ~/dev/raburton-esp8266/esptool2 ]; then
  cd ~/dev/raburton-esp8266
  git clone https://github.com/raburton/esptool2.git
  git clone https://github.com/raburton/rboot
fi

cd ~/dev/raburton-esp8266/esptool2
export XTENSA_BINDIR=$XTENSA_TOOLS_ROOT
make 

So I'm assuming there is something wrong with the environment variables. I've updated them manually in Makefile-user.mk:

ESP_HOME = /opt/Espressif
SMING_HOME = /home/vagrant/dev/Sming/Sming

But i'm guessing something is off - seeing that I was pulling esptool2 into ~/dev/raburton-esp8266/

Any suggestions?

@alexborisov Most probably the executable binary is not in the PATH. I will check this.

@alexborisov Can you get the latest git version and try again?

# Generating image...
Generate firmware images successully in folder out/firmware.
Done

Awesome thanks. I hard reset everything and pulled the latest version. It looks like you fixed issue #12 as well 👍

i cloned the develop version and find that issue is there. the esptool2 path in the Makefile-project.mk shows
'# esptool2 path
ESPTOOL2 ?= esptool2
should this not be
ESPTOOL2 ?= $(ESP_HOME)/esptool2/esptool2
i hardcoded it to my path for the esp_home and it worked

The line ESPTOOL2 ?= esptool2 in your Makefile-project.mk file means check if the ESPTOOL env variable is set and if yes use it otherwise use esptool2 as value.

The project/sming/provision.sh script should have set already the correct env variable.

HAS_ESPTOOL2=`cat $PROFILE_CONF | grep ESPTOOL2 || :`
if [ -z "$HAS_ESPTOOL2" ]; then
  sudo echo "export ESPTOOL2=`pwd`/esptool2" >>  $PROFILE_CONF
  source $PROFILE_CONF
fi 

My suggestion would be to run again the Sming provisioning. This means that from the host machine you should run again

PROJECT=sming vagrant provision

Then check inside of the guest machine, the one that Vagrant created, if inside of the /etc/profile.d/ directory there is an esp8266.sh profile file and if it contains line starting with export ESPTOOL2=

i am using vagrant on a windows machine and i cant seem to provision the projects.
vagrant provision keeps rebuilding the Espressif Home. I use cmder for this, although it does state project = sming but it does not update the Sming files. Thanks for the help. What you suggest seems correct.
