Hello,
I apologize for the extremely naïve question. I have a couple of embedded devices (x86) running the latest version of OpenWRT. I would like to know if I could compile and run batman on these nodes and if so how.
Thanks in advance.
Kartik

There is a howto written by Wesley at http://downloads.open-mesh.net/batman/misc/batmand_howto.pdf
This should describe the process of building and the first steps quite good. You can compile the batmand binary by using a gcc with i386 as target plattform. This should be the case for every standard gcc on non-amd64 i368 distributions. Afterwards you can copy it to your embedded device and use it. I am not up to date with the current development in trunk of openwrt but I think they don't provide packages for gcc yet. So it will not be possible (unless you installed gcc by hand) to compile it on your device running openwrt. This is the really quick and dirty method but you can also create ipkgs with the standard openwrt build environment with the build scripts from https://svn.openwrt.org/openwrt/packages/net/batman/
I would recommend that you use a current snapshot of the batman sources from trunk because they contain a bunch of fixes since the last release (0.3). You can obtain them by running svn export http://downloads.open-mesh.net/svn/batman/trunk/batman/
Best regards, Sven
Hey,
we also have precompiled binaries for x86: http://downloads.open-mesh.net/batman/stable/binaries/i386/ http://downloads.open-mesh.net/batman/development/binaries/i386/
another option is to compile/linu batmand with the -static flag on your x86 (i386) desktop and just copy it, as Sven explained. Unfortunately you won't get an ipkg package with this, but it should run. ;)
best regards Simon

Thx, forgot that one. You should be able to link it statically by using the current version from trunk and running LDFLAGS="-s -static" /usr/bin/make
You can check it with `file batmand`. It should print something like batmand: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.8, stripped
best regards, Sven
Thanks Sven/Simon.
I was able to compile and checking 'file batmand' gave me the output mentioned below.
But running ./batmand ath0 gives me an error.
What configuration do I need to do on the wireless interface on the device?
Thanks Kartik

What error? Is it a dynamic linker error? Does `./batmand` gives the same error? Does `dmesg|tail` gives more information about that problem?
What configuration do I need to do on the wireless interface on the device?
Their are many configurations possible, but I will try to explain a common one: - Get the device in adhoc mode (for example create a vap in adhoc mode with madwifis wlanconfig) - set the essid - set the cellid - set the channel/frequency - start the device - set a unique ip to the device
$ wlanconfig ath0 create wlandev wifi0 wlanmode adhoc $ iwconfig ath0 essid testnet $ iwconfig ath0 ap 02:00:de:ad:be:ef $ iwconfig ath0 channel 10 $ ifconfig ath0 $IP $ ip a add $IP brd $BRDCAST dev ath0 $ ip link set ath0 up
I hope that I didn't forgot anything.
Regards, Sven

Hi Kartik -
please provide info about the error message...
Of course you have to set up the wireless interface...
Here is the startup-script I use on my laptop:
# Load the tun kernel module modprobe tun
# Create Ahdemo mode Madwifi wireless VAP wlanconfig ath0 create wlandev wifi0 wlanmode ahdemo
# Create /etc/resolv.conf with preferred domain name server echo "nameserver 141.1.1.1" > /etc/resolv.conf
# Set up wireless essid, channel and fix the IBSS-ID to avoid cell-splitting # - mandatory to join an existing cell in Ahdemo mode iwconfig ath0 essid olsr.freifunk.net channel 10 ap 02:CA:FF:EE:BA:BE
# Configure IP of VAP interface ip a add 103.130.30.10/8 brd 103.255.255.255 dev ath0
# Switch it on. ip link set ath0 up
# Start batmand with preferred internet gateway batmand -p 103.130.1.67 ath0

Hi,
Is what Philip is compiling batman/robin on the x86 of any interest currently currently known as "Robix" This is fully documented I believe http://robin.forumup.it/viewforum.php?f=12&mforum=robin
Regards,
Ian
