[Fernando Lemos de Mello]

Hi! I am trying to upgrade the kernel of my RedHat 6.2 Linux to a Kernel V 2.4 , but when I type make dep I get errors because of the following files missing!!! : ctype.h fcntl.h stdio.h stdlib.h string.h unistd.h sys/fcntl.h sys/mman.h sys/stat.h sys/types.h     Ah! I also couldn�t use the make menuconfig and make xconfig.... Anyone could help?   Thanks   Fernando.
