I want to complie the kernel 2.6.18.1 with yaffs(a file system) in Vmware Station 6.5. I actually did it. But i also want to test the code
and i found that yaffs supports file or ram emulation. You should complie the code mtdemul2k.o and insmod the mtdemul2k.ko.But when i make the Makefie in the same directory of mtdemul2k.o .Many errors occured. I will post it and want some help~ thanks a lot~

Makefile:

Makefile for NANDemul MTD
#
# NB this is not yet suitable for putting into the kernel tree.
# YAFFS: Yet another Flash File System. A NAND-flash specific file system.

KERNELDIR = /lib/modules/$(shell uname -r)/build


#CFLAGS = -D__KERNEL__ -DMODULE -I$(KERNELDIR)/include -O2 -Wall -g
CFLAGS = -D__KERNEL__ -DMODULE -I$(KERNELDIR)/include -O2 -Wall -g



TARGET = nandemul2k.o

default: $(TARGET)

clean:
rm -f $(TARGET)

$(TARGET): %.o: %.c
gcc -c $(CFLAGS) $< -o $@


The errors i got:
