@H_489_1@
问题原因：Eigen3的bug
解决方法：
打开Thirdparty/g2o/g2o/solvers/linear_solver_eigen.h，将以下代码
1 template <typename MatrixType>
2 class LinearSolverEigen: public LinearSolver<MatrixType>
3 {
4 public:
5 typedef Eigen::SparseMatrix<double,Eigen::ColMajor> SparseMatrix;
6 typedef Eigen::Triplet<double> Triplet;
7 typedef Eigen::PermutationMatrix<Eigen::Dynamic,Eigen::Dynamic,SparseMatrix::Index> PermutationMatrix;
改为@H_489_1@
1 template <typename MatrixType>
public LinearSolver<MatrixType>
3 {
public:
:1.5; color:rgb(128,Eigen::ColMajor> SparseMatrix;
double> Triplet;
8 typedef Eigen::PermutationMatrix<Eigen::Dynamic,int> PermutationMatrix;
