Hi all,<br><br>I&#39;m trying to install GraspIt! in Ubuntu 10.10 
but I&#39;m getting an error with one step. I have followed the installation instructions from the <a href="http://www.cs.columbia.edu/%7Ecmatei/graspit/html-manual/graspit-manual_2.html#id1">manual</a> and I get 
installed &quot;all&quot; correctly, but when I try to do the GraspIt! 
installation:<br>
<br><div style="margin-left: 40px;"><b>qmake <a href="http://graspit.pro/" target="_blank">graspit.pro</a> </b><br><b style="color: rgb(255, 0, 0);">WARNING: /home/robotnik/Graspit/<a href="http://graspit-core.pro:99/" target="_blank">graspit-core.pro:99</a>: Unescaped backslashes are deprecated.</b><br>

<br></div>After that, when I try to run make, I obtain this error:<br><br><div style="margin-left: 40px;"><b>~/Graspit$ make</b><br>g++

</div><br><br>I have followed all instalation steps from the manual (configures, makes, make install, add variables, etc), so I&#39;m lost.<br><br><br><br>Has anyone knows what is my problem and how solve it?<br><br><br>
<br><br><br>Thanks very much for the help,<br>
