2016-08-08 07:51:36 -0500 | asked a question | Instantiating messages from bagfile yields nullpointer Hi, I have problems changing the code from this example so that it fits my needs. This is the scenario: I want to benchmark my code with some real world data. So I'm trying to read a previously recorded bagfile and feed it into my benchmarking code. I use a library that executes a given function n times and then tells me how long it took. My goal is to read a new Now my problem is, that I always end up with a nullpointer when I instantiate a message via the iterator. This is how I implemented it: BagReader.h: BagReader.cpp: Now I initialize my reader giving it the path to a bagfile and adding the two topics i want to read from: Then I do the following to iterate through the messages of the bagfile: |

Hi, I have a benchmarking executable in my project which pulls data from bagfiles. Now I want to copy the folder with my bagfiles into the directory where my binaries end up, because I have hardcoded paths to them in my code. I already tried to copy the folder with my bagfiles by adding this line to my Unfortunately the variable |
