Hardware
For target platform we will use standard PC with D-link DWA-520G (Atheros chipset) WiFi board compatible with hostapd. We install 2 NIC (Intel Ethernet 100) to provide WAN and LAN interfaces.
Build OpenWrt
Downloading
I recommend download latest trunk version. Use subversion repo:[verem@aipetry ~]$ svn checkout https://svn.openwrt.org/openwrt/trunk kamikazeAfter downloading rename directory - append trunk version suffix. I my case:
mv kamikaze kamikaze-r11772
Building prerequisites
For build OpenWrt images i used FC8 (Fedora Core 8) distro. Make sure you have installed:
- gcc
- g++
- bison
- flex
- ncurses-devel
- zlib-devel
Configuration
Goto to source directory and configure:[verem@dev-2 src]$ cd kamikaze-r11772 [verem@dev-2 kamikaze-r11772]$ make menuconfig
Select:
-
Target systemx86 [2.6] - Check:
- Select all packages by default
- Advanced configuration options (for developers)
- Buildsystem settings
- Build the OpenWrt Image Builder
- Image configuration
- override built-in for Network:
- hostapd
- hostapd-mini
- hostapd-utils
- wpa-supplicant
- override built-in for Kernel modules - Network Devices that will be used in your platform, in my case Intel(R) PRO/100+ cards.
- override built-in for Kernel modules - Wireless Drivers that will be used in your platform, in my case Driver for Atheros wireless chipsets
After this changes made exit and confirm changes saving
Building
Start building process:[verem@dev-2 kamikaze-r11772]$ make ++ mkdir -p /home/verem/src/kamikaze-r11772/staging_dir/toolchain-i386_gcc4.1.2 ++ cd /home/verem/src/kamikaze-r11772/staging_dir/toolchain-i386_gcc4.1.2 ++ mkdir -p bin lib include stamp ............
