Core dumped running TUM dataset

[orsivia]

The camera was run for around 5 sec(everything seemed normal), and segmentation fault terminated the program.

I am currently using opencv v2.4.11. I encountered a lot of problems installing opencv library. I manually added #include and #include<opencv2/opencv.hpp> in several files to get the dataset run.

This is the information I got when running TUM dataset:

There is no other information provided. Thank you for help! P.S. I am using ubuntu14.04 (dual boot) on Macbook pro.

Does the error happen for other cases? Could you also try other cases (such as stereo, other dataset, or ROS version)?

OK, now I am sure it has something to do with the OpenCV library. I just uninstalled opencv 2.4.11 and installed 2.4.9(including editing the bashrc file) and the code works fine! There is no need to change any segment of the code!
