Windows filepath build issue

[oasixer]

Here's a weird error, that started happening seemingly overnight: paths being parsed wrong on windows due to path separating backslashes being interpreted as escape sequences??

-- Generated devicetree_generated.h: C:/Shop/nrf_proj/build/rev10/zephyr/include/generated/devicetree_generated.h
-- Including generated dts.cmake file: C:/Shop/nrf_proj/build/rev10/zephyr/dts.cmake

  when parsing string

    c:\Shop\nrf_proj\prj.conf

  Invalid character escape '\S'.

I have no idea what caused this to start happening. Thanks for the help

Hi,

Do you see this issue if you build any samples in the SDK?
Have you tried deleting the build directory completely before rebuilding?

Best regards,
