Issues with librgbdtools and g2o compilation.

edit

Hey,

I am trying to compile ccny_rgbd_tools (master branch) on ROS Hydro, ubuntu 12.04. (After struggling with http://answers.ros.org/question/20969... ).

I run the rosdep install command, and it installs libg2o. (ros-hydro-libg2o). Then I get these errors:

Linking CXX shared library lib/librgbdtools.so
make[3]: Leaving directory /home/tanmay/hydro_workspace/sisl_sandbox/ccny_rgbd_tools/lib_rgbdtools/rgbdtools_git/build' [ 87%] Built target rgbdtools make[3]: Entering directory/home/tanmay/hydro_workspace/sisl_sandbox/ccny_rgbd_tools/lib_rgbdtools/rgbdtools_git/build'

When I remove libg2o and run rosmake --pre-clean, it cannot find some header files. I tried manually including these, but it still comes up as errors.

Any suggestions as to how I can solve this inconsistency, guys? @idryanov

Thanks in advance!
