I guess you're talking about version 173 of udev, there is no such thing as 1.73. If you use udev, then your kernel must have CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT enabled. If you let Buildroot build your kernel, then Buildroot will automatically ensure that your kernel is configured with those two options enabled. If you build your kernel manually outside of Buildroot, then you must enable those options, otherwise udev will not work. I guess this is where your problem is: check your kernel configuration. > I noticed udev 1.14 does not build when the build ccache is ON. Honestly, we don't really care about udev 114 since the current Buildroot version contains udev 173, and this one appears to build properly with ccache enabled.
