segment fault

[JasonSun623]

Hi,thanks for your great work, when I run roslaunch localization_bag_play.launch, got segment fault. I debug localiziation_node with CLion ,segment fault locates at g2o::ParameterSE3Offset* zero_offset = new g2o::ParameterSE3Offset in localization.cpp. My ros environment is Melodic.Looking forward to your reply

Hi, this repo was only tested on Kinetic. the segment fault might be because of new versions of ROS or G2O.
Please make sure you install the correct version of G2O:

git clone https://github.com/RainerKuemmerle/g2o
cd g2o ; git checkout deafc01ee8315b9405351fb145238c5d62f82dc7
mkdir build ; cd build
cmake .. ; make -j4
sudo make install
