Atmelsam/mkrzero - arm-none-eabi-g++ not found

1

I’m building for a MKRZERO device using Windows 10. The project was setup by a friend and he had it all working in VSCODE and PlatformIO on two machines. For some reason on my machine I’m getting

...
Building in release mode
Compiling .pio\build\mkr1000USB\src\main.cpp.o
'arm-none-eabi-g++' is not recognized as an internal or external command,
operable program or batch file.

I’ve found a few other threads here with similar situations, but none of the help has been helpful. I think I’m encountering a different issue and I’d appreciate help.

Here’s my platformio.ini:

I’ve verified:

All instances of arm-none-eabi-g++.exe on my machine run on Windows. E.g:

~\.platformio\.cache\tmp\pkg-installing-ouvj7cyi\bin> .\arm-none-eabi-g++.exe --version
arm-none-eabi-g++.exe (GNU Tools for Arm Embedded Processors 7-2017-q4-major) 7.2.1 20170904 (release) [ARM/embedded-7-branch revision 255204]

and

~\OneDrive - Kindel Systems\Documents\ArduinoData\packages\arduino\tools\arm-none-eabi-gcc\7-2017q4\bin]> .\arm-none-eabi-g++.exe --version

What am I missing? What could be misconfigured?

This is the temporary install directory, it shouldn’t be there but in C:\Users\<user>\.platformio\packages\toolchain-gccarmnoneeabi (and then bin\)

Does that directory exist? If it exists, it may have been corrupted, try and delete it to trigger a redownload.

Yep, that directory is there. I deleted it and did Build again and a download was triggered.

As you guessed, it was somehow corrupted before, because this fixed it!

Thank you!!!
