CMD does not support UNC paths as current directories.
ninja: build stopped: subcommand failed.

Other Steps to Reproduce

Install VSC.
Install ESP-IDF
Create project hello_world

Full Clean

Then the build system interprets some paths as UNC paths.

The system is completely installed on a mapped drive V: Alle paths are accessible with regular paths starting with V:. But somehow UNC paths are introduced. (The current computer name is EL-WIN10)

I have checked existing issues, online documentation and the Troubleshooting Guide

• I confirm I have checked existing issues, online documentation and Troubleshooting guide.

UNC paths are not supported. The problem is not only in CMD, but also in other tools like CMake, Git or CCache. They does not work well with UNC or long paths - see limitation: espressif/idf-installer#103

One possible workaround is to use subst command to map long path to new drive letter:

subst "R:" "my_super_long_path"

[ELNL]

Thank you this response @georgik .
To shorten the paths I already used a 'drive mapping' in Windows 10, using the Windows UI. I am not sure is 'subst' works the same way. I will try this. (It will take a few weeks perhaps to do it...)

This issue has been marked as stale since there are no activities, and this will be closed in 5 days if there are no further activities

[arantius]

I still have exactly this problem. I can build the project (just "hello world" example for now), but I can't run menuconfig. My project is already on a mapped drive, and that's the path I gave when creating the project. But when I try to menuconfig, it uses the UNC path equivalent, instead of the drive letter.

[arantius]

Actually, as soon as I've tried to do menuconfig, I can't build anymore for the same UNC path error. If I create a new project and never try to menuconfig it then I can build all I like.

[brianignacio5]

It might be related to some default settings that are resolving ${workspaceFolder} to the real project path instead of the mapped location. For example, try this vsix installer and set idf.buildPathWin and idf.sdkconfigFilePath in <your project>\.vscode\settings.json to build and sdkconfig paths using the mapped drive.
