Compiling miniupdate for OpenWrt

Download the corresponding SDK from http://openwrt.org/ to the build box.

For example, using http://downloads.openwrt.org/backfire/10.03.1-rc5/brcm-2.4/OpenWrt-SDK-brcm-2.4-for-Linux-i686-gcc-3.4.6_uClibc-0.9.30.1.tar.bz2

cd /u/openwrt/
wget "http://downloads.openwrt.org/backfire/10.03.1-rc5/brcm-2.4/OpenWrt-SDK-brcm-2.4-for-Linux-i686-gcc-3.4.6_uClibc-0.9.30.1.tar.bz2"
tar jxvf OpenWrt-SDK-brcm-2.4-for-Linux-i686-gcc-3.4.6_uClibc-0.9.30.1.tar.bz2
cd OpenWrt-SDK-brcm-2.4-for-Linux-i686-gcc-3.4.6_uClibc-0.9.30.1/

Create the following folder structure:

$ cd /u/openwrt/OpenWrt-SDK-brcm-2.4-for-Linux-i686-gcc-3.4.6_uClibc-0.9.30.1/

$ tree package/miniupdate/
package/miniupdate/
├── files
│   └── miniupdate.init
└── Makefile

1 directory, 2 files

cd /u/openwrt/OpenWrt-SDK-brcm-2.4-for-Linux-i686-gcc-3.4.6_uClibc-0.9.30.1/
mkdir -p package/miniupdate/files

Create the Makefile:

Makefile

# miniupdate Makefile for OpenWrt backfire
# (c) 2011 Michael Fung 

include $(TOPDIR)/rules.mk

# this line is needed for fixing "ld-uClibc.so.0 not found" config error.

$(eval $(call BuildPackage,miniupdate))

Create the miniupdate.init file:

miniupdate.init

#!/bin/sh /etc/rc.common

START=99

start() {
        [ -f /etc/miniupdate.conf ] && /usr/bin/miniupdate -d -c /etc/miniupdate.conf
}

stop() {
        killall miniupdate
}

Improve the init script!

make package/miniupdate/compile

The resulting .ipk file is in the bin folder.

Transfer the .ip file to the device and install it:

opkg install .ipk

Enable auto start after the config is ok:

/etc/init.d/miniupdate enable
