udev/udevd.c:37:26: error: sys/signalfd.h: No such file or directory

Thanks for the suggestion but I have compiled the kernel from source and I have this file in the same place as You... but what sould I do with the file then? Should I somewhere add a symlink to the directory? Thanks for any help

I don't understand what the error means.... pls help :-(
