Error when building dvo_benchmark?

[091405ccj]

Hello! I can build the dvo_core, dvo_slam, dvo_ros successfully but it failed when building dvo_benchmark? The error message is as follows:

Can anyone give me some suggestions? Thank you!!

By the way, I installed g2o before. If i should delete the g2o firstly and install the old version then?
