自己从源码编译dd-wrt
从源码构建DD-WRT不很困难，但是比编译openwrt要难一点。一、安装系统和依赖的软件包
需要一个linux系统和相关的编译工具，我严重向大家推荐debian和ubuntu，因为它们比较方便。
编译需要的软件包如下：
Automake v1.9.4
GNU Make v?
GCC/G++ v4
ncurses
binutils
tar
bzip2
gzip
g++
patch
flex
bison
make
gettext
unzip
libz-dev
libc headers
安装以上的软件包用以命令： sudo apt-get install gcc g++ binutils patch bzip2 flex bison make gettext unzipzlib1g-dev libc6二、获取DD-WRT的源码
DD-WRT的源码文件结构如下：
src/ source
router/ packages
linux/ kernel
opt/ make/control
通过以下命令获取DD-WRT的最新源码:svn co svn://svn.dd-wrt.com/DD-WRT .这个命令会下载DD-WRT的全部源码到当前目录中，因为它的源码比较大，可能有2G左右，而且到国外的速度比较慢，所以可能需要一天才能下载完。
你需要下载 3.4.6 和4.1.0 版本的mipsl uclibc 工具链，可以从以下地址下载到：
http://www.dd-wrt.com/dd-wrtv2/d ... .debian.sp1.tar.bz2
把文件下载完后，解压到/homte/db90h目录中。
三、编译DD-WRT
要编译DD-WRT你只需要简单的做以下步骤:
0. 执行 ready_ddwrt.sh 和 ready_ddwrt_root.sh (这个脚本在后面).
1. 添加 4.1.0 toolchains 执行文件目录到环境变量中。
PATH=$PATH:/home/db90h/toolchains/4.1.0-uclibc/bin
2. 进入DD-WRT/opt 目录运行 ./install.sh。或者执行不同的./install_×××，以编译出不同的固件版本.
以下两个在编译前需要执行的脚本文件：
重要提醒：这两个脚本都依赖于你系统中dd-wrt的下载目录和gcc toolchain的解压目录。所以你在运行前都要修改两个脚本中的内容以适合本机的情况，否则不能起到预期的作用。

then

echo
echo i.e.:

echo
exit 1

echo usage:
echo ready_ddwrt_root.sh
echo
echo i.e.:
echo ready_ddwrt_root.sh /home/db90h/DD-WRT /home/db90h/3.4.6-ucliblc-0.9.28
echo

mkdir -p /opt
rm /opt/3.3.6
ln -s $TCHAIN /opt/3.3.6
rm /GruppenLW
ln -s $DDROOT/image /GruppenLWecho All done!
四、更改DD-WRT
进入 /src/router 目录，你会看到 .config* 文件. 使用 'make menuconfig' 编辑配置文件. 可以进入 /src/router/busybox 目录选择要编译的busybox选项。
Change micro configuration: WARNING: Before and after doing this you need to copy and restore the "Internal Options" section of the .config files. These options don't seem to be in #the Config template.
cd DD-WRT/src/router
cp .config .config_micro
make menuconfig
cp .config_micro .config
Change micro Busybox configuration:
cd DD-WRT/src/router/busybox
cp .config .config_micro
make menuconfig
cp .config_micro .config
Change micro kernel configuration:
cd DD-WRT/src/router/busybox
cp .config .config_micro
make menuconfig
cp .config_micro .config

不错!!

其实那些提示没的文件或目录的（如红色标出的）源码里本来就没有的呢
