Compile Menggunakan Development Trunk

Development Trunk tampaknya paling RECOMMENDED

Lakukan sebagai user biasa

svn co svn://svn.openwrt.org/openwrt/trunk/ ~/openwrt.trunk/trunk
cd ~/openwrt.trunk/trunk/
./scripts/feeds update
./scripts/feeds install meshwizard openssh-server openssh-client
./scripts/feeds install freifunk-common freifunk-gwcheck freifunk-mapupdate

./scripts/feeds install kamailio4 kamailio asterisk18 asterisk11 coova-chilli
./scripts/feeds update -a
./scripts/feeds install -a
make clean
make defconfig
make menuconfig
make world

Hasilnya akan berada di folder

~/openwrt.trunk/trunk/bin/brcm47xx
