Uninstaller is still unsigned, as currently building and signing in 'wine' and running Linux osslsigncode inside Inno Setup inside wine is awkward. Closes https://github.com/espressif/esp-idf/issues/1909 TW20810

The CMake-based build system is only supported on 64-bit versions of Windows.

Introduction
|
|
============
|
|
|
|
ESP-IDF requires some prerequisite tools to be installed so you can build firmware for the ESP32. The prerequisite tools include Git, a cross-compiler and the CMake build tool. We'll go over each one in this document.
|
|
|
|
For this Getting Started we're going to use a command prompt, but after ESP-IDF is installed you can use :doc:`Eclipse <eclipse-setup>` or another graphical IDE with CMake support instead.
|
|
|
|
.. note::
|
|
The GNU Make based build system requires the MSYS2_ Unix compatibility environment on Windows. The CMake-based build system does not require this environment.
|
|
|
|
ESP-IDF Tools Installer
|
|
=======================
|
|
|
|
The easiest way to install ESP-IDF's prerequisites is to download the ESP-IDF Tools installer from this URL:
|
|
|
|
https://dl.espressif.com/dl/esp-idf-tools-setup-1.2.exe
|
|
|
|
The installer will automatically install the ESP32 Xtensa gcc toolchain, Ninja_ build tool, and a configuration tool called mconf-idf_. The installer can also download and run installers for CMake_ and Python_ 2.7 if these are not already installed on the computer.
|
|
|
|
By default, the installer updates the Windows ``Path`` environment variable so all of these tools can be run from anywhere. If you disable this option, you will need to configure the environment where you are using ESP-IDF (terminal or chosen IDE) with the correct paths.
|
|
|
|
Note that this installer is for the ESP-IDF Tools package, it doesn't include ESP-IDF itself.
|
|
|
|
Installing Git
|
|
==============
|
|
|
|
The ESP-IDF tools installer does not install Git. By default, the getting started guide assumes you will be using Git on the command line. You can download and install a command line Git for Windows (along with the "Git Bash" terminal) from `Git For Windows`_.
|
|
|
|
If you prefer to use a different graphical Git client, then you can install one such as `Github Desktop`. You will need to translate the Git commands in the Getting Started guide for use with your chosen Git client.
|
|
|
|
Using a Terminal
|
|
================
|
|
|
|
For the remaining Getting Started steps, we're going to use a terminal command prompt. It doesn't matter which command prompt you use:
|
|
|
|
- You can use the built-in Windows Command Prompt, under the Start menu. All Windows command line instructions in this documentation are "batch" commands for use with the Windows Command Prompt.
|
|
- You can use the "Git Bash" terminal which is part of `Git for Windows`_. This uses the same "bash" command prompt syntax as is given for Mac OS or Linux. You can find it in the Start menu once installed.
|
|
- If you have MSYS2_ installed (maybe from a previous ESP-IDF version), then you can also use the MSYS terminal.
|
|
|
|
Next Steps
