一、编译错误：
      LD      init/built-in.o
      LD      .tmp_vmlinux1
    drivers/built-in.o: In function `mxc_hdmi_remove':
    clkdev.c:(.text+0x125e0): undefined reference to `switch_dev_unregister'
    clkdev.c:(.text+0x125ec): undefined reference to `switch_dev_unregister'
    drivers/built-in.o: In function `hotplug_worker':
    clkdev.c:(.text+0x1445c): undefined reference to `switch_set_state'
    clkdev.c:(.text+0x1446c): undefined reference to `switch_set_state'
    clkdev.c:(.text+0x1466c): undefined reference to `switch_set_state'
    clkdev.c:(.text+0x1467c): undefined reference to `switch_set_state'
    drivers/built-in.o: In function `mxc_hdmi_probe':

    clkdev.c:(.devinit.text+0x3d4): undefined reference to `switch_dev_register'
    sound/built-in.o: In function `usb_audio_disconnect':
    last.c:(.text+0x16b20): undefined reference to `switch_set_state'
    last.c:(.text+0x16b28): undefined reference to `switch_dev_unregister'
    sound/built-in.o: In function `usb_audio_probe':

    last.c:(.text+0x36944): undefined reference to `switch_set_state'
    sound/built-in.o: In function `imx_wm8962_remove':

    last.c:(.devinit.text+0x718): undefined reference to `switch_set_state'
    make: *** [.tmp_vmlinux1] Error 

    解决方法：
        主要是make menuconfig打开swith这个选项，详情参考文章1。

二、编译错误：
      LD      kernel/built-in.o
      CC      drivers/gpu/drm/drm_auth.o
    In file included from include/drm/drmP.h::,
                     from drivers/gpu/drm/drm_auth.c::
    include/drm/drm.h::: fatal error: sys/types.h: No such file or directory
    compilation terminated.
    make[]: *** [drivers/gpu/drm/drm_auth.o] Error
    make[]: *** [drivers/gpu/drm] Error
    make[]: *** [drivers/gpu] Error
    make: *** [drivers] Error 

    解决方法：
        由于采用了Android自带的编译器，本来就不能用Android的编译器，导致出现了这个问题，所以换成Linux Qt的编译器就行了。

三、编译错误：
      CC [M]  drivers/usb/gadget/audio.o
      CC [M]  drivers/usb/gadget/ether.o
    drivers/usb/gadget/ether.c: In function 'rndis_do_config':
    drivers/usb/gadget/ether.c::: error: too few arguments to function 'rndis_bind_config'
    drivers/usb/gadget/f_rndis.c::: note: declared here
    drivers/usb/gadget/ether.c::: warning: control reaches end of non-void function [-Wreturn-type]
    make[]: *** [drivers/usb/gadget/ether.o] Error
    make[]: *** [drivers/usb/gadget] Error
    make[]: *** [drivers/usb] Error
    make: *** [drivers] Error 

    解决方法：
        make menuconfig 去掉这部分驱动也许就行了。目前本人通过选择一个能够编译通过的文件系统
        Device Drivers  --->
            [*] USB support  --->
                <*>   USB Gadget Support  --->
                    <*>   USB Gadget Drivers (Gadget Filesystem (EXPERIMENTAL))  --->
                        (X) Gadget Filesystem (EXPERIMENTAL)     

四、编译错误：
    Qt@aplex:~/kernel/linuxQt_kernel$ make uImage
      CHK     include/linux/version.h
      CHK     include/generated/utsrelease.h
    make[]: `include/generated/mach-types.h' is up to date.
      CALL    scripts/checksyscalls.sh
      CHK     include/generated/compile.h
      CC      drivers/input/touchscreen/ar1020-spi.o
    drivers/input/touchscreen/ar1020-spi.c: In function 'ar1020_spi_probe':
    drivers/input/touchscreen/ar1020-spi.c::: error: implicit declaration of function 'set_irq_type' [-Werror=implicit-function-declaration]
    drivers/input/touchscreen/ar1020-spi.c::: warning: ignoring return value of 'request_irq', declared with attribute warn_unused_result [-Wunused-result]
    cc1: some warnings being treated as errors

    make[]: *** [drivers/input/touchscreen/ar1020-spi.o] Error
    make[]: *** [drivers/input/touchscreen] Error
    make[]: *** [drivers/input] Error
    make: *** [drivers] Error 

    解决方法：
        //set_irq_type(i, IRQ_TYPE_EDGE_RISING);  // 将中断引发类型放在request_irq()中
        if ( >= (ret=request_irq(i, test_irq_handler_func, IRQ_TYPE_EDGE_RISING,
                        "AR1020 IRQ", priv))){
            ......
        }
