cant find function from the g2o package when compiling dvo_slam

[geoeo]

Hello,

Apparently the function headers of g2o have changed since dvo_slam was published?
Can anybody confirm or deny this? / Had this problem?

The compile error is:

/home/marc/Workspace/ROS/tum_ros/src/dvo_slam/dvo_slam/src/keyframe_graph.cpp: In constructor ‘dvo_slam::internal::KeyframeGraphImpl::KeyframeGraphImpl()’:
/home/marc/Workspace/ROS/tum_ros/src/dvo_slam/dvo_slam/src/keyframe_graph.cpp:140:5: error: no matching function for call to ‘g2o::BlockSolver<g2o::BlockSolverTraits<6, 3> >::BlockSolver(dvo_slam::internal::KeyframeGraphImpl::LinearSolver*)’
     )));
     ^

Do I have to roll back my g2o verison?

If you use the latest g2o, the following codes should work :
Modify codes below // g2o setup

std::unique_ptr<BlockSolver::LinearSolverType> linearSolver = g2o::make_unique<LinearSolver>();
std::unique_ptr <BlockSolver> block_solver ( new BlockSolver( std::move(linearSolver)) );
keyframegraph_.setAlgorithm(
    new g2o::OptimizationAlgorithmDogleg(
        std::move(block_solver)
    )
);
