标题: linux找不到mach/regs-gpio.h文件
我把TQ2440开发板的linux源代码放到了虚拟机上面，用的是redhat 4 企业版，并且把EABI编译器安装上了，编译内核的时候没有问题，能生成zImage，可我编写驱动程序的时候，linux/下的文件都能找到，比如 #include <linux/fs.h>,但是mach下的却找不到，#include <mach/regs-gpio.h> 就会出现 No directory。。。。，但是涉及硬件必须要用啊，郁闷，我想知道，编译器是怎么寻找头文件的，这种情况到底是怎么回事，一概不知啊，恳请哪路大神帮小弟一把！


Makefile的内容




ifneq ($(KERNELRELEASE),)
        obj-m :=EmbedSky_gpio.o
ARCH =arm
CROSS_COMPILE =arm-linux-
else
        KERNELDIR =/opt/EmbedSky/linux-2.6.30.4/
        #KERNELDIR=/lib/modules/$(shell uname -r)/build
        #KERNELDIR=/usr/src/kernels/2.6.21-1.3194.fc7-i686
        PWD := $(shell pwd)
default:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) modules
clean:
        rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c
endif





结果：

我把regs-gpio.h放到我的驱动文件目录下，依然不好使。
