Does the Romi bot work with C++? Is it intended to? The RomiReference example project works fine for me in Java.
The C++ version (whether deploy robot code, simulate code on desktop) dumps screenfuls of errors, starting with:
C:\Users\npodr.gradle\caches\transforms-2\files-2.1\c8a90f4e34412eb91233d26a46d5e20f\wpilibc-cpp-2021.1.2-headers\frc/Watchdog.h(53): error C2061: syntax error: identifier ‘Watchdog’
It looks like that error is coming from the full desktop Visual Studio compiler. What version of Visual Studio (full, not vs code) do you have installed. For the Romi setup to work, you need the latest update for Visual Studio 2019. Older versions will not work.
I just updated Visual Studio 2017 to Visual Studio 2019. Problem solved!
Thanks so much!
To clarify, is Visual Studio 2019 required for Romi/C++ to work at all? Or is it only required if there are earlier Visual Studio versions already present?
I just tried running RomiReference (with “Enable Desktop Support” checked) on a machine that had no Visual Studio at all, but did have all the VSCode stuff. I got the errors below. After installing Visual Studio they went away:

Yes. Romi C++ code runs on the desktop, meaning that a supported desktop C++ compiler (Visual Studio 2019 on Windows) is required.
And the documentation has been updated to call that out.
