ROS-I tesseract and trajopt install

edit

Are you still having this problem? I installed everything last week and did not have to do anything special to get either tesseract or trajopt_ros to compile.

Did you run rosdep install .. before building?

I was able to fix it by installing and building from source. I did not run rosdep install before building but Eigen already existed on my computer but under the usr/include folder and not the usr/local/include folder where it was expected.

The typical workflow before building ROS pkgs from source (such as tesseract and trajopt_ros) would be to run

rosdep check --from-paths $CATKIN_WS/src --ignore-src

that way you can make sure you have all dependencies.

re: expected in /usr/local: I don't know that is true. I don't ..

.. have an Eigen install there and things built OK.

In general using system provided packages is recommended, as this has the least chance of interfering with other packages/build processes and is automatically kept up-to-date.

Ok I will try to clean things up and see if I can get it working

Let me know if things don't work. They should, so that should be fixed.
