Windows 11 - Error compiling Pyside2

[munkybutt]

Hey!

I am having issues with building on Windows11.
I have setup a VM, so clean windows with no other possible conflicts.
Followed the steps in the guide:
https://github.com/AcademySoftwareFoundation/OpenRV/blob/main/docs/build_system/config_windows.md
Followed advice in the few other issues and discussions that seemed relevant to see if they will help and no luck so far.

Error output:

Any advice would be appreciated

I wonder if you are hitting the most annoying Windows maximum path length when building the pyside2 dependency.

NOTE: Path Length
Even as of Windows 11, for legacy reason, a default system path length is still limited to 254 bytes long. For that reason we strongly suggest cloning OpenRV into drive's root directory e.g.: C:
https://github.com/AcademySoftwareFoundation/OpenRV/blob/main/docs/build_system/config_windows.md#note-path-length

And you are building from an MSYS2-MinGW64 shell right ?

Thanks for the reply - I am building from MSYS2-MinGW64
I disabled the path limit on Windows at your suggestion but still no luck, less errors though - I will try clone to the root and build again

Magic - moving it to C:/ allowed for a successful build.
Thank you for the help @bernard-laberge-adsk!
