This is why we generally separate out messages into their own packages.  It lets you separate the interface (msgs/srvs) from the node/library.<div><br></div><div>Josh<br><br><div class="gmail_quote">On Tue, Aug 24, 2010 at 8:04 AM, Daniel Grollman <span dir="ltr">&lt;<a href="mailto:daniel.grollman@epfl.ch">daniel.grollman@epfl.ch</a>&gt;</span> wrote:<br>

<br>
        I&#39;m looking to build the message classes for a package without building<br>
the actual binaries.  Do-able?  Easy?<br>
<br>
Details:  My robot&#39;s node requires libraries and hardware that my<br>
desktop doesn&#39;t have.  I&#39;d like to watch the topics being broadcast by<br>
my robot from my desktop, but I can&#39;t because the message classes don&#39;t<br>
exist.<br>
<br>
Thanks,<br>
<br>
Dan<br>
