再次提供下文。热心的samuel昨天在coding4fun聚会的时候帮我编译了这个http服
务端软件使之在路由器上运行。

此外我们还做了一个有趣的设置。

家中路由器上插有一个USB声卡，连在家中音响上。我们在coding4fun远程安装了
mpd，使路由器（上面带有300G古典音乐）可以直接 播放音乐，用PC或iPhone点歌
都可以。

当然iPhone点歌时要绕很大一圈，先由iPhone上3G，进入Internet，登录家中路由
器。看似用iPhone对着路由器，其实信号 围北京转了约一圈了。

方法记录在这里：

第零步是安装声卡内核模块。

第一是在路由器安装mpd

    先创建一个安装目的的，路由器上8M闪存不够装这个。往 /etc/opkg.conf里添加 
    dest mpd /home/mpd
    然后可以装了：

第二是添加audio用户组（对，我也不知道为什么包管理器不包办此事）

    # echo audio:x:29:root >> /etc/group

第三是修改mpd.conf（需注意的是USB默认输出不一定是PCM，用alsamixer一查看
可知）。

第四是启动mpd

    # LD_LIBRARY_PATH=/home/mpd/usr/lib /home/mpd/usr/bin/mpd /home/mpd/etc/mpd.conf

    用/etc/init.d/mpd start不管用的，因为有意将mpd安装在路由器闪存外了。


完成了。我试了Ubuntu上的点播客户端Ario，因为它排第一（头文字A）。可以
用，就没再试别的了。

播放ogg时约占 WL-500G v1的一半CPU资源，samuel说这很不错了，因为这路由器
里没有协处理器，ogg需要浮点运算转换成整数运算。
