Debugging C++ applications remotely

This article describes how to use Microsoft Visual Studio 2019 for rsYocto C++ development. The newer releases of Visual Studio are capable to work as embedded Linux development IDE for ARMv7A. Visual Studio can use the gdb-Server and SSHfor communicating with Linux. On rsYocto all required components for Visual Studio are pre-installed.

The following illustration shows how Linux and Microsoft Visual Studio work together:

Installing Microsoft Visual Studio for Linux development

1. Download one Version of Microsoft Visual Studio 2019 for Windows
2. Follow the Visual Studio installer and include "Linux Development for C++" as workload to your installation
3. Finish the installation

Creating a new Linux project

1. Open Mirosoft Visual Studio 2019 and Create a new project
2. Select as language "C++" and platform "Linux" and choose "Console App"
3. Press "next and give your project a name
4. A new Visual Studio Solution should appear with a getting started guide
5. This Guide shows how to configure the connection of the remote Linux machine
6. Please follow this instructions with this settings:
   • Platform: ARM
   • Host Name: IPv4-Address of your Board:
   • Port: 22
   • User name: root
   • Authentication type: Password
   • Password: eit
   • To change the IP-Address later navigate to Tools/Options/Cross Platform, click there the "Remove"-Button and then "Add"
7. At this point the Visual Studio is ready for Linux C++ development

Known Issues with Visual Studio and Linux

• Read the console output only and ingnore the error windows
• Ingore the "rysnc could not start error" (rsync is installed properly)
• After issues try to clean and rebuild the solution
