Hi, I am trying to build wlroots, but get this error in meson logs:
Command line: `cc /home/Chris/wlroots/build/meson-private/tmprxphcsub/testfile.c -o /home/Chris/wlroots/build/meson-private/tmprxphcsub/output.obj -c -D_FILE_OFFSET_BITS=64 -O0 -std=c11` -> 1
stderr:
In file included from /home/Chris/wlroots/build/meson-private/tmprxphcsub/testfile.c:2:
/usr/include/sys/signalfd.h:17:17: error: 'O_CLOEXEC' undeclared here (not in a function); did you mean 'FD_CLOEXEC'?
   17 |   SFD_CLOEXEC = O_CLOEXEC,

Header "sys/signalfd.h" has symbol "SFD_CLOEXEC" : NO

subprojects/wayland-1.20.0/meson.build:83:3: ERROR: Problem encountered: SFD_CLOEXEC is needed to compile Wayland libraries

 Is there any solution for this? Or is it a bug that needs to be fixed?
I am using Windows 10 Version 22H2 Build: 19045.3448.
CPU: Ryzen 5 2600
GPU: Nvidia RTX 2070
