Ubuntu 16.04 安装 g2o 问题汇总

问题1：

报错信息：
/home/robot/g2o/g2o/types/slam2d/edge_se2_pointxy_bearing.cpp: In member function ‘virtual void g2o::EdgeSE2PointXYBearing::initialEstimate(const VertexSet&, g2o::OptimizableGraph::Vertex*)’:
/home/robot/g2o/g2o/types/slam2d/edge_se2_pointxy_bearing.cpp:50:52: error: no matching function for call to ‘g2o::SE2::setRotation(Eigen::Rotation2D::Scalar)’
     t.setRotation(t.rotation().angle()+_measurement);

处理方法：

In g2o/types/slam2d/edge_se2_pointxy_bearing.cpp line 51 change:

t.setRotation(t.rotation().angle()+_measurement);

to

t.setRotation((Eigen::Rotation2Dd)(t.rotation().angle()+_measurement));

 

问题2： 强制类型转换

/home/robot/g2o/g2o/solvers/eigen/linear_solver_eigen.h:98:37:   required from ‘bool g2o::LinearSolverEigen::solve(const g2o::SparseBlockMatrix&, double*, double*) [with MatrixType = Eigen::Matrix]’
/home/robot/g2o/g2o/solvers/eigen/solver_eigen.cpp:111:1:   required from here
/usr/local/include/eigen3/Eigen/src/Core/util/StaticAssert.h:125:9: error: ‘YOU_MIXED_DIFFERENT_NUMERIC_TYPES__YOU_NEED_TO_USE_THE_CAST_METHOD_OF_MATRIXBASE_TO_CAST_NUMERIC_TYPES_EXPLICITLY’ is not a member of ‘Eigen::internal::static_assertion’
         if (Eigen::internal::static_assertion(CONDITION)>::MS

处理方法：

打开   /g2o/g2o/solvers/linear_solver_eigen.h，将以下代码
template
class LinearSolverEigen: public LinearSolver
{
public:
typedef Eigen::SparseMatrix SparseMatrix;
typedef Eigen::Triplet Triplet;
typedef Eigen::PermutationMatrixSparseMatrix::Index> PermutationMatrix;

修改为：

template
class LinearSolverEigen: public LinearSolver
{
public:
typedef Eigen::SparseMatrix SparseMatrix;
typedef Eigen::Triplet Triplet;
typedef Eigen::PermutationMatrixint> PermutationMatrix;

 

问题3： 强制类型转换

/home/robot/g2o/g2o/examples/tutorial_slam2d/simulator.cpp:78:39:   required from here
/usr/local/include/eigen3/Eigen/src/Core/util/StaticAssert.h:125:9: error: ‘FLOATING_POINT_ARGUMENT_PASSED__INTEGER_WAS_EXPECTED’ is not a member of ‘Eigen::internal::static_assertion’
         if (Eigen::internal::static_assertion(CONDITION)>::MS
         ^
/usr/local/include/eigen3/Eigen/src/Core/PlainObjectBase.h:778:7: note: in expansion of macro ‘EIGEN_STATIC_ASSERT’
       EIGEN_STATIC_ASSERT(is_integer,

处理方法：

 g2o/g2o/examples/tutorial_slam2d/simulator.cpp:78的代码如下所示：

VectorXd probLimits(MO_NUM_ELEMS);
      for (int i = 0; i < probLimits.size(); ++i)
        probLimits[i] = (i + 1) / (double) MO_NUM_ELEMS;

修改成：

      VectorXd probLimits;
      probLimits.resize(MO_NUM_ELEMS);
      for (int i = 0; i < probLimits.size(); ++i)
        probLimits[i] = (i + 1) / (double) MO_NUM_ELEMS;
