I think you should give proper path of eigen files for EIGEN directory variable in cmake_gui
@chaiein Thank you for your reply! I found when I add the "set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -O3 -march=native")” in the cmakelist my code can run normally .But I really don't know why . The problem is that when I add this to the cmakelist the other code will go core dumping,so do you have any advice to run g2o without the "-Wall -O3"?
@ZulunZhu Thank you for your sharing! Works for me too! Amazing... How did you even think of this...?
@ZulunZhu Thank you for your answer, it solves the problem I met(On MacOS10.14.2). I guess -march=native
is the key. The problem has confused me very long time.
@ZulunZhu Thanks for the solution. Phew.. after a long time, finally I get the solution.
Thanks a lot. PS: @chaiein Thanks for the pointer.
Hi I met the Segmentation fault when I use the g2o imitating the ORB-SLAM2 to optimize my pose graph.
Eigen::Matrix<double,3,3> Rcw; Eigen::Matrix<double,3,1> tcw; Rcw<<0.999991,-0.00307419,-0.00307221, 0.00307749,0.999995,0.00106957, 0.00306891,-0.00107902,0.999995; tcw<<-0.00634032, -0.0152401, 0.849042; g2o::Sim3 S_test(Rcw,tcw,1.0); cout<<"S_test:"<<S_test<<endl; g2o::EdgeSim3 e = new g2o::EdgeSim3(); cout << "e.nIDj " << nIDj << " e.nIDi " << nIDi << endl; e->setVertex(1, dynamic_castg2o::OptimizableGraph::Vertex(optimizer.vertex(nIDj))); e->setVertex(0, dynamic_castg2o::OptimizableGraph::Vertex*(optimizer.vertex(nIDi))); e->setMeasurement(S_test);
I tried a lot of value of setMeasurement(),but every time my code will go core dumping at this function. It is very confusing that ORB-SLAM2 will not go down in that function.
Does anyone have the same problem? Appreciating if there is any help.
