Dear Javier,

I would recommend to use the Yocto Project http://www.yoctoproject.org/ and bitbake for cross compiling. There exists even some meta-packages for this.

https://github.com/bmwcarit/meta-ros

This runs very nicely and is relatively easy to configure. It is build on ROS Hydro. I would migrate to Hydro anyway, because Fuerte is EOL.


I am working with Yocto/Dora branch and ROS, using the meta-ros packages.


Cheers,

Markus

Hello everybody. My name is Javier and I am new in this mailing list.

I work with embedded systems (bare metal programming and embedded GNU/Linux too) and I am learning ROS by my own at home.

some months ago I wrote an entry in my personal blog (http://industriaembebidahoy.com/efsystems/es/node/61) about how to cross-compile ROS Fuerte for a RPI Board with a with a BuildRoot based rootfs (http://buildroot.uclibc.org/) based on other post I found in Internet (http://uchile-spl.wikidot.com/).

Now, Im trying to add support for ROS in Buildroot for automatic cross-compile of ROS in new rootfs for any architecture supported for Buildroot.

I have used rosinstall-generator to obtain a list of packages for a ros-base groovy instalation whith the idea of add all this packages into a virtual package in BuildRoot, but I have some troubles when I try to cross-compile.

My problem is the dependencies among packages, so I would like to know if anyone could tell me which is the correct order for compile and install separate packages without dependencies problems so I could configure Buildroot for doing the compilation in the correct order.

Also, I think that not all packages are needed for a running system, so I would like to know which packages I could omit for an embedded system (I will not develop in this system, only run). 

Anyone could help me?

Thanks in advance.

Javier.
