I was building the g2o_with_orbslam2 fallow the install step. meet error:

i installed eigen3 3.2.92, don't know how to fix this , thanks

install another version of eigen will solve this problem.

Did you solved this problem?

// bigB = expm(bigA) //Eigen::MatrixExponential me(bigA); //me.compute(bigB); bigB = bigA.exp(); 前三行代码注释掉，添加最后一行
