This tutorial shows how to set up a project in CLion for ESP32 development on Windows, covering all the necessary steps in great detail. Starting from downloading and installing the esp-idf development framework, we’ll take a closer look at how esp-idf uses specific environment variables and a dedicated Python environment to compile programs. We’ll create a new CLion project from one of the esp-idf examples and adjust the project settings so that CLion knows about all of the underlying esp-idf dependencies. With the correct project settings, we will close the tutorial by demonstrating some of CLion’s code-insight features and show how to compile, flash, and monitor programs for your ESP32 board directly from within the IDE. 00:00 Intro 00:21 Preparations and initial installations 02:42 Setting up a project in CLion 06:39 Code insight in CLion 08:02 Flashing and monitoring your ESP-32 chip Learn more: Download CLion: https://www.jetbrains.com/clion/download esp-idf GitHub repository: https://github.com/espressif/esp-idf CLion documentation on embedded development: https://www.jetbrains.com/help/clion/embedded-overview.html

In this webinar, JetBrains developer advocates Matt Ellis and Timur Doumler show five different ways to do remote development in C++ using the CLion IDE. First, we show the "thin client" approach with the brand new JetBrains Gateway. We then compare this to the older method of remote development with local sources and point out the differences. After that, we look at CLion’s custom toolchains for developing on WSL and Docker containers. Then, we dive into remote debugging, where we make a Raspberry Pi blink an LED and discuss the difference between “Remote Debug” and “Remote GDB Server” modes. Finally, we show how to collaborate remotely using Code With Me. 00:00 Introduction 05:00 Remote development with Gateway 20:45 Remote development with local sources 32:00 Containers and virtual machines: WSL 36:22 Containers and virtual machines: Docker 43:29 Making Raspberry Pi blink an LED by debugging remotely from CLion 56:11 Code With Me, collaborative editing (Matt now blinks an LED on Timur’s Raspberry Pi!) 01:07:55 Recap of the options, comparison table 01:11:36 Back to remote development with Gateway 01:14:14 Q&A and wrap-up

5 Approaches to Remote C++ Development With CLion
26.07.2022
When debugging C or C++ code in CLion, you can explore the underlying assembly code. To open the disassembly view, right-click a frame in the debugger tab and select Disassemble. This opens the disassembly view side-by-side with your source code and highlights the current execution line in both. You can freely switch between debugging in the C/C++ and assembly views and step through lines of code or instructions. Both views follow each other while debugging. Disassemble on demand works for both Intel and ARM assembly, and it also works when using remote debugging, like for embedded development.
