linux内核：2.6.10 摄像头：中星zc0301b 硬件平台：华恒270开发板
操作基础：知道linux内核编译过程；会linux命令基本操作；有合适的摄像头；会linux－arm程序下载到开发板的流程
1、建立可编译驱动
1.0、将gspcav1-20071224.tar.gz解压到linux-2.6.10/drivers/usb/media下，修改linux-2.6.10/drivers/usb／Makefile文件，
在其后添加：
obj-$(CONFIG_USB_SPCA5XX) += media/
1.2、添加 gspcav1-20071224 编译选项：修改linux-2.6.10/drivers/usb/media/Kconfig
添加：
config USB_SPCA5XX
tristate "USB SPCA5XX Sunplus/Vimicro/Sonix jpeg Cameras"
depends on USB && VIDEO_DEV
---help---
Say Y or M here if you want to use one of these webcams:

tristate "USB SPCA5XX Sunplus/Vimicro/Sonix jpeg Cameras"
depends on USB && VIDEO_DEV
---help---
Say Y or M here if you want to use one of these webcams:
The built-in microphone is enabled by selecting USB Audio support.
This driver uses the Video For Linux API. You must say Y or M to
"Video For Linux" (under Character Devices) to use this driver.
Information on this API and pointers to "v4l" programs may be found
at.
"Video For Linux" (under Character Devices) to use this driver.
Information on this API and pointers to "v4l" programs may be found
at
To compile this driver as a module, choose M here: the
module will be called spca5xx.
1.3、修改linux-2.6.10/drivers/usb/media/Makefile
添加：
obj-$(CONFIG_USB_SPCA5XX) += gspcav1-20071224/ ＃注意“/”不要漏掉
1.4、把gspcav1-20071224/Makefile修改成： 注意Makfile文件的格式
gspca-objs := gspca_core.o decoder/gspcadecoder.o
obj-$(CONFIG_USB_SPCA5XX) += gspca.o
module will be called spca5xx.

obj-$(CONFIG_USB_SPCA5XX) += gspca.o
clean:
rm -f *.[oas] .*.flags *.ko .*.cmd .*.d .*.tmp *.mod.c
rm -rf .tmp_versions
2、编译内核
内核配置为
（1）Multimedia devices --->
*Video For Linux
（2） USB support --->
*Support for Host-side USB
--- USB Host Controller Drivers
*OHCI HCD support
（3）--- USB Multimedia devices
USB SPCA5XX Sunplus/Vimicro/Sonix jpeg Cameras
修改gspcav1-20071224/gspca_core.c文件
//static const char gspca_version[] = GSPCA_VERSION;改为
static const char gspca_version[] = "00.60.00";
添加一个宏定义
#define VID_HARDWARE_GSPCA 0ff
rm -f *.[oas] .*.flags *.ko .*.cmd .*.d .*.tmp *.mod.c
rm -rf .tmp_versions

make clean；make zImage ;make modules
几分钟过后，带有摄像头驱动的内核就编译好了，下载到开发板，成功识别摄像头后会显示
drivers/usb/media/gspcav1-20071224/gspca_core.c: USB GSPCA camera found.(ZC3XX)
usbcore: registered new driver gspca
drivers/usb/media/gspcav1-20071224/gspca_core.c: gspca driver 01.00.20 registerd

3、移植servfox
解压servfox-R1_1_3.tar.gz，将Makfile.arm 改为Makefile make，即可生成arm下可执行的servfox，传到板子上并执行./servfox -d /dev/video0 -g -s 640x480 -w 7070，视频服务器就跑起来了；
/tmp # servfox version: 1.1.3 date: 11:12:2005 (C)
wrong spca5xx device
VIDIOCSWIN failed
: Invalid argument
Waiting .... for connection. CTrl_c to stop !!!!
Got connection from 192.168.2.7
解压servfox-R1_1_3.tar.gz，将Makfile.arm 改为Makefile make，即可生成arm下可执行的servfox，传到板子上并执行./servfox -d /dev/video0 -g -s 640x480 -w 7070，视频服务器就跑起来了；

Got connection from 192.168.2.7
4、在pc机上安装spcaview
解压spcaview-20071224.tar.gz 直接make；make install即可
在pc上运行./spcaview -g -w 192.168.1.17即可在电脑上看到视频了
解压spcaview-20071224.tar.gz 直接make；make install即可
在pc上运行./spcaview -g -w 192.168.1.17即可在电脑上看到视频了
5、移植boa服务器
解压boa-0.94.13.tar.gz,进入boa-0.94.13/src执行./configure生成Makefile，修改Makefile，
将 CC = gcc 和 CPP = gcc - E 改为你自己的交叉编译工具
# make
解压boa-0.94.13.tar.gz,进入boa-0.94.13/src执行./configure生成Makefile，修改Makefile，
将 CC = gcc 和 CPP = gcc - E 改为你自己的交叉编译工具
# make
util.c:100:1: error: pasting "t" and "->" does not give a valid preprocessing token
make: *** [util.o] Error 1
make: *** [util.o] Error 1
解决方法：
修改 src/compat.h
找到
#define TIMEZONE_OFFSET(foo) foo##->tm_gmtoff
修改成
#define TIMEZONE_OFFSET(foo) (foo)->tm_gmtoff
然后
debian:/home/a/sss/boa-0.94.13/src# make clean
debian:/home/a/sss/boa-0.94.13/src# make
修改 src/compat.h
找到
#define TIMEZONE_OFFSET(foo) foo##->tm_gmtoff
修改成
#define TIMEZONE_OFFSET(foo) (foo)->tm_gmtoff
然后
debian:/home/a/sss/boa-0.94.13/src# make clean
debian:/home/a/sss/boa-0.94.13/src# make
然后除去调试信息，以减小体积
# arm-linux-strip boa
修改boa.conf,改为
# Boa v0.94 configuration file
# File format has not changed from 0.93
# File format has changed little from 0.92
# version changes are noted in the comments
#
# The Boa configuration file is parsed with a lex/yacc or flex/bison
# generated parser. If it reports an error, the line number will be
# provided; it should be easy to spot. The syntax of each of these
# rules is very simple, and they can occur in any order. Where possible
# these directives mimic those of NCSA httpd 1.3; I saw no reason to
# introduce gratuitous differences.

复制/etc/mime.types 和boa-0.94.13/src/boa到 /nfs/www 说明：/nfs/www为我自己服务器的挂载目录，看自己情况而定
建立/nfs/www/cgi-bin/目录
建立/nfs/www/cgi-bin/目录
在开发板上建立/var/www目录，然后把pc的/nfs/www挂载到开发板的/var/www目录，执行./boa,服务器就跑起来了。具体情况看个人的配置文件
将spcaview-20071224/http-java-applet里的内容拷贝到/nfs/www/view文件夹下，并解压JWebcamPlayer.jar到view文件夹
在pc浏览器上输入192.168.2.222/view/index-sample.html按照需要安装自己的java－plug，好了刷新就可以在网页上看到视频了；
Goodluck!

注释掉下面两句话：

二、移植spcaview-20061208到arm上
在编译spcaview之前需要移植SDL库文件，下载SDL-1.2.14.tar.gz解压进入执行
./configure --prefix=/root/sdl --disable-video-qtopia --disable-video-dummy --disable-video-fbcon --disable-video-dga --disable-arts --disable-esd --disable-alsa --disable-cdrom --disable-video-x11 --disable-nasm --target=arm-linux --host=arm-linux --enable-video-fbcon
指定安装目录在/root/sdl
然后修改/root/SDL-1.2.14/include/SDL_config.h第207行，注释掉
//#define SDL_INPUT_LINUXEV 1
//#define SDL_INPUT_TSLIB 1
因为我暂时没有输入设备，否则在编译spcaview时会出现找不到/dev/mouse的错误
//#define SDL_INPUT_TSLIB 1
因为我暂时没有输入设备，否则在编译spcaview时会出现找不到/dev/mouse的错误
make
make install
编译spcaview，修改Makefile
CC=arm-linux-gcc -staticCPP=arm-linux-g++
SDLLIBS = -L/root/sdl/lib -lSDL -lpthread
SDLFLAGS = -I/root/sdl/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT

spcacat: $(OBJCAT)
arm-linux-gcc -static $(SERVFLAGS) -o spcacat $(OBJCAT) $(SERVLIBS)
然后make就可以了
