error: no matching function for call to ‘g2o::BlockSolver<g2o::BlockSolverTraits<6, 3> >::BlockSolver(SlamLinearSolver*&)’

[Shivani1796]

Hello, I have already installed g2o as per you have shown here https://github.com/RainerKuemmerle/g2o ,
also tried using this one https://github.com/RainerKuemmerle/g2o/releases/tag/20170730_git
Both of the solution didn't worked for this one.
Do we need to modify the code ? I am using the same original code as you have given.
Please help me solve this issue.
