 Subject   Re: [ros-users] ogre_tools broken on CTurtle/Snow leopard
 

  I installed the nvidia cg package. And then I added the following entry to  the rosdep.yaml file in visualization_common.

The make process for ogre_tools still fails for me like before (undefined symbol "_main").

I think the wrong-architecture errors you're getting are probably the root of your problems.  It seems like your build environment may not be set up correctly.

What do:
file /opt/local/lib/libboost_thread-mt.dylib

and:
gcc -v

output?
Josh
