after compiling rgbdslam successfully, I tried to start rgbdslam. All I got was a "symbol lookup error":

/home/robot/ros/rgbdslam/bin/rgbdslam: symbol lookup error: /home/robot/ros/rgbdslam/lib/ undefined symbol: gsl_multimin_fdfminimizer_vector_bfgs2

After searching the web for a while I found a related topic here.

So I changed the LD_LIBRARY_PATH to /opt/ros/fuerte/lib:/usr/lib and exported it but I didn't fix the error.

GSL Version:libgsl0ldbl 1.15+dfsg-1build1 ROS Fuerte Ubuntu 12.04

Can somebody help me?

Cheers! Georg

are these packages installed "gsl-bin libgsl0-dev"?

weird, that is a runtime error or a linker error?

Could be that you need to deinstall ros-fuerte-libg2o (and rebuild rgbdslam)

I tried running

roslaunch openni_launch openni.launch ..... this runs with out issues

but then

george@ulisa:~$ rosrun rgbdslam rgbdslam /home/george/fuerte_workspace/rgbdslam_freiburg/rgbdslam/bin/rgbdslam: Symbol `_ZTVN3g2o19UniformCostFunctionE' has different size in shared object, consider re-linking /home/george/fuerte_workspace/rgbdslam_freiburg/rgbdslam/bin/rgbdslam: symbol lookup error: /home/george/fuerte_workspace/rgbdslam_freiburg/rgbdslam/bin/rgbdslam: undefined symbol: _ZN3g2o11globalStatsE

I am new to ROS .. what causing this ?? By the way I had run this few months back and it had worked .. I cant understand whats happening now.
