I got a problem on compiling ESP32 examples. Follow the esp-idf_getting_started_guide. But it occurs some errors when running 'make configmenu'. I have download the latest esp-idf from github, and install necessary libs.
my linux environment is:
ubuntu 14.04.1 LTS
It was downloaded from https://drive.google.com/folderview?id= ... sp=sharing
I use it to compile esp8266, and now I want to compile esp32.
How could I config the environment?

the error info:

Hi zxwang,

I downloaded the ESP8266 VM from Google Drive and ran the following steps in a terminal (mostly from Linux Setup Guide):

Code: Select all

sudo apt-get update
sudo apt-get install git wget make libncurses-dev flex bison gperf python python-serial
cd
git clone --recursive https://github.com/espressif/esp-idf.git
export IDF_PATH=~/esp-idf
cd esp-idf/examples/01_hello_world
make menuconfig

... and the configuration menu appears correctly.

Is it possible something else with the VM is causing the problem?
