[GUIDE] Build AsusWRT for newifi mini on Ubuntu 14.04 32bit

Manually preparing the build environment

install packages

apt-get install libncurses5 libncurses5-dev m4 bison gawk flex libstdc++6-4.4-dev g++-4.4 g++ \
git gitk zlib1g-dev autoconf autopoint libtool shtool autogen mtd-utils intltool sharutils \
docbook-xsl-* libstdc++5 texinfo dos2unix xsltproc make pkg-config

prepare source to, ex, ～/asuswrt

cd ~
wget https://dlsvr04.asus.com/pub/ASUS/wireless/RT-AC1200HP/GPL_RT_AC1200HP_30043808228.zip
unzip GPL_RT_AC1200HP_30043808228.zip
tar zxvf GPL_RT-AC1200HP_3.0.0.4.380.8228-g3af35f9.tgz

setup development system

cd asuswrt/
cp -r tools/brcm /opt/
tar -jxvf tools/buildroot-gcc342.tar.bz2 -C /opt/
export PATH=$PATH:/opt/brcm/hndtools-mipsel-linux/bin:/opt/brcm/hndtools-mipsel-uclibc/bin:/opt/buildroot-gcc342/bin

Fix 5GHz Wi-Fi

vi src-ra-mt7620/linux/linux-2.6.36.x/drivers/net/wireless/rlt_wifi_ap/Makefile

edit first line as follows

obj-m += rlt_wifi.o

Enable TProxy

vi src-ra-mt7620/linux/linux-2.6.36.x/config_base

set y to these three config blow:

CONFIG_NETFILTER_TPROXY=y
CONFIG_NETFILTER_XT_TARGET_TPROXY=y
CONFIG_NETFILTER_XT_MATCH_SOCKET=y

Build firmware

cd src-ra-mt7620/
make distclean
make RT-AC1200HP
