Missing locale setting

[mhilden-mhs]

Hi all,

I am getting a warning from the Perl infrastructure when I am building my VisualGDB 6.0 project that is targeted to the ESP-IDF v4.4 toolchain.

This is what I’m seeing. From what I can tell, this needs to be resolved via a Visual Studio setting (I am on version 17.9.7 and Windows 11), but this issue has persisted for a few versions. My code works fine but I’d like this warning to go away for me and everyone else on our team. Where do I find the setting to configure the locale and make Perl happy?

Thanks,

~Matt

Hi,

VisualGDB forces the locale to be en_US.UTF-8 as otherwise some build tools would show localized error messages, confusing the message parsing logic (e.g. trying to understand the base directory for the relative paths in subsequent messages).

You can try overriding the environment of the CMake/Make commands via VisualGDB Project Properties -> Build Settings. It should override the default value.

[mhilden-mhs]

Thanks for your reply. I played around in the CMake section of the VisualGDB Project Properties but I still can figure it out. Can you please provide some specific values to use (and where to place them) so I can increase my chances of overriding the build environment correctly?

Hi,

The exact setting depends on how your project is setup. If you would like us to point out a specific setting, please make sure you can reproduce the problem on a new project created from scratch, and than share the screenshots showing how the project was created (every step of the wizard and every other window where you changed any settings).

This is happening on a brand new “blink” sample project with absolutely no changes from default. Screenshots and build details are below.

Hi,

Thanks for the screenshots. For this project type you can override the LANG variable via VisualGDB Project Properties as shown below:

Hi,

We wouldn’t expect any specific output, since we don’t use Strawberry Perl. It’s generally up to you to figure out what LANG value will make it happy; all we can do is show how to override it on the VisualGDB side.

You can double-check that VisualGDB passes the correct value to ESP-IDF by dumping the command-line used by VisualGDB (with the environment) into a batch file as shown here. The file will contain all environment variables including LANG and running it manually should produce the same results as via VisualGDB. You can then experiment with different values by editing the file, and once you find the value that works, enter it via VisualGDB Project Properties.

[mhilden-mhs]

Thanks for your help. The clue I needed was that it might be Strawberry Perl that’s to blame. I don’t use this anymore (it was for an old project) so I uninstalled it, rebooted my Windows machine, and then re-built the Python portion of the VisualGDB project via the VisualGDB project settings dialog. The locale error is gone now.
