makefile

LINUX1.0内核源代码,学习LINUX编程的一定要看。

#
# Makefile for the kernel character device drivers.
#
# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here
# unless it's something special (ie not a .c file).
#
# Note 2! The CFLAGS definitions are now inherited from the
# parent makes..
