Finally got through the Groovy install in OSX 10.7. No compile errors for rviz. At runtime:

rosrun rviz rviz
[ INFO] [1370005319.743413000]: rviz version 1.9.29
[ INFO] [1370005319.743491000]: compiled against OGRE version 1.7.4 (Cthugha)

Ok, got it to work. I had to explicitly link librviz against the Cocoa libraries. I changed

target_link_libraries(${PROJECT_NAME}
  ${Boost_LIBRARIES}
  ${catkin_LIBRARIES}
  ${OGRE_LIBRARIES}
  ${OPENGL_LIBRARIES}
  ${QT_LIBRARIES}
  assimp
  yaml-cpp
)

in CMakeLists (in the rviz directory) to:

target_link_libraries(${PROJECT_NAME}
  ${Boost_LIBRARIES}
  ${catkin_LIBRARIES}
  ${OGRE_LIBRARIES}
  ${OPENGL_LIBRARIES}
  ${QT_LIBRARIES}
  ${rviz_ADDITIONAL_LIBRARIES}
  assimp
  yaml-cpp
)

William had defined the cocoa libraries as rviz_ADDITIONAL_LIBRARIES in the CMakeLists 2 layers up. I didn't think this should be necessary, but I just tried it and it worked. I may re-investigate to see if it's something that isn't my fault. If so, I'll submit a patch.

It looks like rviz compiled against a different copy of librviz.dylib, than the one being dynamically loaded at /opt/ros/groovy/lib/librviz.dylib.

What is the output of rospack find rviz and how did you install/build groovy from source, did you intentionally install it to /opt/ros/groovy or did you have an older version in /opt/ros/groovy and you are running it from a local installation?

More generically, that error means the executable rviz is looking for the _GetCurrentProcess symbol in the librviz.dylib dynamic library, but it is not in there. That symbol comes from the OS X Cocoa framework, which you have to link against at build time or you get a linkedit error. That should be fixed in rviz currently, see:

https://github.com/ros-visualization/rviz/pull/563/files#L0R26

That makes me think that you might have different versions of rviz the executable and librviz.dylib the library.

Hi William, I did explicitly install groovy to /opt/ros/groovy, and from what I can tell, I put both my rviz executable and librviz there at the same time. I don't know what other version of librviz this would be linking against. I had fuerte installed, but I don't think there are any remnants.

When I run image_view in my devel_isolated folder, it works without at hitch (and as far as I can tell, it makes the same call to GetCurrentProcess and compiles againsts librviz... I think). The Rviz I'm running is definitely the one I compiled with the full groovy install.

I just recompiled librviz and rviz. Same result. I also confirmed that I have the changes pointed to for tlinking against the Cocoa Framework. Also moved the /opt/... librviz dylib, so now I get: Symbol not found .../ros_catkin_ws/devel_isolated/rviz/lib/librviz.dylib

The pastebin doesn't contain the building of rviz, just the configuration of CMake. It looks like you didn't actually rebuild it. I don't really have a clue why this is happening, I'll try to reproduce it later.

William ( 2013-05-31 15:22:15 -0500 )edit

I built it, I just didn't include that in the pastebin, didn't think it'd be helpful. Here's the whole shebang: http://pastebin.com/JAS4KdiH

With regard to your first question, after making and installation, "rospack find rviz" yields "/opt/ros/groovy/share/rviz"
