boa cgi

我把2440的一些资源整理在了一起，和大家分享一下
秀几张图，

2440的web服务器是/usr/sbin/boa,配置文件是/etc/boa/boa.conf,
这是友善已经做好的一个服务器支持软件，并开机自动运行，
和window下的iis作用一样，要想自己给2440搭建，可以到
http://www.boa.org/
下载源码编译，不过我编译时出现处错误，按照天嵌的Step By Step说明书改了几处源代码便可编译成功
也可refer to http://blog.mcuol.com/User/langke279/Article/36253_1.htm
对于cgi，是一个类似asp的动态网页生成的咚咚，友善的leds.cgi貌似没用到cgi库,不过是几行shell脚本
用cgi库函数可以很方便的创建,提交一些表单
如果要使用cgi库的话---http://www.boutell.com/cgic/cgic205.tar.gz
编译后生成libcgic.a，这个就是需要的洞洞
编译用到此库中函数的c时，用arm-linux-gcc -o myfile myfile.c libcgic.a
