The Windows section of the user manual contains details about building on Windows:<br>

The Python section explains the issue with Python on Windows. We are governed by<br>
GDB and what it needs.<br>

I have just completed an ARM build on Win10 (fully updated) without error. I<br>
noticed in the report's command line you are building under:<br>
<br>
C:/msys64/home/brendan/<wbr>development/rtems/4.12<br>
<br>
This results in file names that are longer than 260 characters which is the<br>
default max. path length for the win32 API. Please review the comments here:<br>

<br>
I am currently using 'D:\opt\rtems\rsb.git' for the RSB repo which works.<br>
