= Cross Compile Software Sources for Linksys WRT54G =

First of all I assume you know how to compile normale stuff for the x86 architecture... so I'm not going deep into that.

In this document we are going to see how to cross compile software for the mipsel architecture, to make it run on the
Linksys WRT54GL router.

I used Freifunk Firmware and OpenWRT Firmware to test this stuff, any version should be fine

== Install the compiler ==

First of all we need a compiler for such architecture, so grab a shell on your linux box and download the following

{{{
cd ~
wget ftp://ftp.linksys.com/opensourcecode/wrt54gl/4.30.9/WRT54GL_v4.30.9_US.tgz
tar -zxvf WRT54GL_v4.30.9_US.tgz
}}}

Please note that this compiler will produce binaries executable on the WRT54G router, but not on the Fonera. If you know that compiler should be used for the Fonera please update this Wiki :)

Now we have to add there new tools to out path
{{{
export PATH="~/WRT54GL_4_30_9_1101_US/tools/brcm/hndtools-mipsel-linux/bin:~/WRT54GL_4_30_9_1101_US/tools/brcm/hndtools-mipsel-uclibc/bin:$PATH"
}}}

Congratulation, you installed the compiler

== Compile lastest version of OLSR ==

Install the compiler as in the first section of this page

Now lets get the newest OLSR sources
{{{
cd ~
wget http://www.olsr.org/releases/0.5/olsrd-0.5.0.tar.bz2
tar -jxvf olsrd-0.5.0.tar.bz2
}}}

please note that file names may slighly change over time

now edit the followgin Makefile {{{olsrd-0.5.0/make/Makefile.linux}}} and add
{{{
CC=mipsel-uclibc-gcc
}}}

Cool, now just

{{{
make
make libs
}}}

and you have your mipsel binaries
copy the olsrd binary and the libs to the WRT54G manually with scp

Please not that using the original libs plugin files compiled against olsrd-0.4.10 will cause olsrd-0.5.x to segmentain fault

== Compile lastest version of BATMAN ==

TODO:

Sources are here
{{{
svn co https://dev.open-mesh.net/svn/batman/trunk/batman/
}}}

BATMAN Makefile already provides tools for compile in mipsel architecture, assuming you have the OpenWRT SDK tools installed, as soon
as I understand how it works I'll update the wiki :) Or someelse will do it before me!

== Compile lastest version of RASTA ==

Install the compiler as in the first section of this page

Get the source code of RASTA with svn

{{{
cd ~
svn co https://minerva.netgroup.uniroma2.it/svn/rastayaqosa/rasta/trunk rasta
}}}

add in the Makefile proper compiler
{{{
CC=mipsel-uclibc-gcc
}}}

Now just Make !
