arm-linux-gcc版本：4.3.3编译通过
一、视频服务器
0、所需文件
gspcav1-20071224.tar.gz
spcaview-20071224.tar.gz
servfox-R1_1_3.tar.gz
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-$(CONFIG_USB_SPCA5XX) += media/
1.2、添加 gspcav1-20071224 编译选项：修改linux-2.6.10/drivers/usb/media/Kconfig
添加：
config USB_SPCA5XX
tristate "USB SPCA5XX Sunplus/Vimicro/Sonix jpeg Cameras"
depends on USB && VIDEO_DEV
---help---
Say Y or M here if you want to use one of these webcams:
The built-in microphone is enabled by selecting USB Audio support.
This driver uses the Video For Linux API. You must say Y or M to
"Video For Linux" (under Character Devices) to use this driver.
Information on this API and pointers to "v4l" programs may be found
at .
To compile this driver as a module, choose M here: the
module will be called spca5xx.
1.3、修改linux-2.6.10/drivers/usb/media/Makefile
添加：
obj-$(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
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
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
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
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
util.c:100:1: error: pasting "t" and "->" does not give a valid preprocessing token
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
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.
# $Id: boa.conf,v 1.25 2002/03/22 04:33:09 jnelson Exp $
# The "ServerRoot" is not in this configuration file. It can be compiled
# into the server (see defines.h) or specified on the command line with
# the -c option, for example:
#
# boa -c /usr/local/boa
# Port: The port Boa runs on. The default port for http servers is 80.
# If it is less than 1024, the server must be started as root.
Port 80
# Listen: the Internet address to bind(2) to. If you leave it out,
# it takes the behavior before 0.93.17.2, which is to bind to all
# addresses (INADDR_ANY). You only get one "Listen" directive,
# if you want service on multiple IP addresses, you have three choices:
# 1. Run boa without a "Listen" directive
# a. All addresses are treated the same; makes sense if the addresses
# are localhost, ppp, and eth0.
# b. Use the VirtualHost directive below to point requests to different
# files. Should be good for a very large number of addresses (web
# hosting clients).
# 2. Run one copy of boa per IP address, each has its own configuration
# with a "Listen" directive. No big deal up to a few tens of addresses.
# Nice separation between clients.
# The name you provide gets run through inet_aton(3), so you have to use dotted
# quad notation. This configuration is too important to trust some DNS.
#Listen 192.68.0.5
# User: The name or UID the server should run as.
# Group: The group name or GID the server should run as.
User nobody
Group 0
# ServerAdmin: The email address where server problems should be sent.
# Note: this is not currently used, except as an environment variable
# for CGIs.
#ServerAdmin
# ErrorLog: The location of the error log file. If this does not start
# with /, it is considered relative to the server root.
# Set to /dev/null if you don't want errors logged.
# If unset, defaults to /dev/stderr
#ErrorLog /var/log/boa/error_log
# Please NOTE: Sending the logs to a pipe ('|'), as shown below,
# is somewhat experimental and might fail under heavy load.
# "Usual libc implementations of printf will stall the whole
# process if the receiving end of a pipe stops reading."
#ErrorLog "|/usr/sbin/cronolog --symlink=/var/log/boa/error_log /var/log/boa/error-%Y%m%d.log"
# AccessLog: The location of the access log file. If this does not
# start with /, it is considered relative to the server root.
# Comment out or set to /dev/null (less effective) to disable
# Access logging.
#AccessLog /var/log/boa/access_log
# Please NOTE: Sending the logs to a pipe ('|'), as shown below,
# is somewhat experimental and might fail under heavy load.
# "Usual libc implementations of printf will stall the whole
# process if the receiving end of a pipe stops reading."
#AccessLog "|/usr/sbin/cronolog --symlink=/var/log/boa/access_log /var/log/boa/access-%Y%m%d.log"
# UseLocaltime: Logical switch. Uncomment to use localtime
# instead of UTC time
#UseLocaltime
# VerboseCGILogs: this is just a logical switch.
# It simply notes the start and stop times of cgis in the error log
# Comment out to disable.
#VerboseCGILogs
# ServerName: the name of this server that should be sent back to
# clients if different than that returned by gethostname + gethostbyname
ServerName
# VirtualHost: a logical switch.
# Comment out to disable.
# Given DocumentRoot /var/www, requests on interface 'A' or IP 'IP-A'
# become /var/www/IP-A.
# Example: becomes /var/www/127.0.0.1
#
# Not used until version 0.93.17.2. This "feature" also breaks commonlog
# output rules, it prepends the interface number to each access_log line.
# You are expected to fix that problem with a postprocessing script.
#VirtualHost
# DocumentRoot: The root directory of the HTML documents.
# Comment out to disable server non user files.
DocumentRoot /var/www
# UserDir: The name of the directory which is appended onto a user's home
# directory if a ~user request is recieved.
UserDir public_html
# DirectoryIndex: Name of the file to use as a pre-written HTML
# directory index. Please MAKE AND USE THESE FILES. On the
# fly creation of directory indexes can be _slow_.
# Comment out to always use DirectoryMaker
DirectoryIndex index.html
# DirectoryMaker: Name of program used to create a directory listing.
# Comment out to disable directory listings. If both this and
# DirectoryIndex are commented out, accessing a directory will give
# an error (though accessing files in the directory are still ok).
#DirectoryMaker /usr/lib/boa/boa_indexer
# DirectoryCache: If DirectoryIndex doesn't exist, and DirectoryMaker
# has been commented out, the the on-the-fly indexing of Boa can be used
# to generate indexes of directories. Be warned that the output is
# extremely minimal and can cause delays when slow disks are used.
# Note: The DirectoryCache must be writable by the same user/group that
# Boa runs as.
# DirectoryCache /var/spool/boa/dircache
# KeepAliveMax: Number of KeepAlive requests to allow per connection
# Comment out, or set to 0 to disable keepalive processing
KeepAliveMax 1000
# KeepAliveTimeout: seconds to wait before keepalive connection times out
KeepAliveTimeout 10
# MimeTypes: This is the file that is used to generate mime type pairs
# and Content-Type fields for boa.
# Set to /dev/null if you do not want to load a mime types file.
# Do *not* comment out (better use AddType!)
MimeTypes /var/www/mime.types
# DefaultType: MIME type used if the file extension is unknown, or there
# is no file extension.
DefaultType text/html
# CGIPath: The value of the $PATH environment variable given to CGI progs.
CGIPath /bin:/usr/bin:/usr/local/bin
# SinglePostLimit: The maximum allowable number of bytes in
# a single POST. Default is normally 1MB.
# AddType: adds types without editing mime.types
# Example: AddType type extension [extension ...]
# Uncomment the next line if you want .cgi files to execute from anywhere
#AddType application/x-httpd-cgi cgi
# Redirect, Alias, and ScriptAlias all have the same semantics -- they
# match the beginning of a request and take appropriate action. Use
# Redirect for other servers, Alias for the same server, and ScriptAlias
# to enable directories for script execution.
# Redirect allows you to tell clients about documents which used to exist in
# your server's namespace, but do not anymore. This allows you to tell the
# clients where to look for the relocated document.
# Example: Redirect /bar
# Aliases: Aliases one path to another.
# Example: Alias /path1/bar /path2/foo
#Alias /doc /usr/doc
# ScriptAlias: Maps a virtual path to a directory for serving scripts
# Example: ScriptAlias /htbin/ /www/htbin/
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
ScriptAlias /index.html /var/www/index.html
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
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!
----------------------------
错误的地方：
错误No such user: nobody
User 0
Group 0
错误boa.c:211 - getpwuid: No such file or directory
(3)修改src/boa.c
注释掉下面两句话：
if (passwdbuf == NULL) {
DIE(”getpwuid”);
}
if (initgroups(passwdbuf->pw_name, passwdbuf->pw_gid) == -1) {
DIE(”initgroups”);
}
为
#if 0
if (passwdbuf == NULL) {
DIE(”getpwuid”);
}
if (initgroups(passwdbuf->pw_name, passwdbuf->pw_gid) == -1) {
DIE(”initgroups”);
}
#endif
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
make
make install
编译spcaview，修改Makefile
CC=arm-linux-gcc -static
CPP=arm-linux-g++
SDLLIBS = -L/root/sdl/lib -lSDL -lpthread
SDLFLAGS = -I/root/sdl/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT
spcaserv: $(OBJSERVER)
arm-linux-gcc -static $(SERVFLAGS) -o spcaserv $(OBJSERVER) $(SERVLIBS)
spcacat: $(OBJCAT)
arm-linux-gcc -static $(SERVFLAGS) -o spcacat $(OBJCAT) $(SERVLIBS)
然后make就可以了
