Dear Javier,<br>
<br>
I would recommend to use the Yocto Project
<a href="http://www.yoctoproject.org/" target="_blank">http://www.yoctoproject.org/</a> and bitbake for cross compiling. There
exists even some meta-packages for this.<br>
<br>
<a href="https://github.com/bmwcarit/meta-ros" target="_blank">https://github.com/bmwcarit/meta-ros</a><br>
<br>
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.<br>
<br>
<br>
I am working with Yocto/Dora branch and ROS, using the meta-ros
packages.<br>
<br>
<br>
Cheers,<br>
<br>

<div>Hello everybody. My name is Javier and I am new in this
mailing list.</div>
<div><br>
</div>
<div>I work with embedded systems (bare metal programming and
embedded GNU/Linux too) and I am learning ROS by my own at
home.</div>
<div><br>
</div>
<div>some months ago I wrote an entry in my personal blog (<a href="http://industriaembebidahoy.com/efsystems/es/node/61" target="_blank">http://industriaembebidahoy.com/efsystems/es/node/61</a>)
about how to cross-compile ROS Fuerte for a RPI Board with a
with a BuildRoot based rootfs (<a href="http://buildroot.uclibc.org/" target="_blank">http://buildroot.uclibc.org/</a>)
based on other post I found in Internet (<a href="http://uchile-spl.wikidot.com/" target="_blank">http://uchile-spl.wikidot.com/</a>).</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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). </div>
<div>
<br>
</div>
<div>Anyone could help me?</div>
<div><br>
</div>
<div>Thanks in advance.</div>
<div><br>
</div>
<div>Javier.</div>
