Does your rosdep.yaml file include a listing for '10.04' under ubuntu
or just '9.10'? The file should be in your $ROS_ROOT path(should be
/home/karnad/myros/ros/ros for you). I had to add '10.04' when I first
installed ROS.<br>

My guess: the shared object in /opt/ros/lib for libboost is a 32-bit
ELF, whereas I need a 64-bit version. I deduced this by comparing the
default boost shared object with the one in the /opt/ros library:<br>
<br>
<span style="font-family: courier new,monospace;">$ file
/opt/ros/lib/libboost_thread-gcc42-mt-1_37.so.1.37.0 </span><br
style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">/opt/ros/lib/libboost_thread-gcc42-mt-1_37.so.1.37.0:

dynamically linked, stripped</span><br
style="font-family: courier new,monospace;">
<br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">$ file

<br>
Could anyone tell me how I can recompile the libraries that go into
/opt/ros/lib? Or more generally, how can I get it to work without using
a different (32-bit) Linux?<br>
<br>
Thanks in advance!<br>
