Memory Errors while using gpg

[prakveer]

Hi, I am a master's student at University of Pennsylvania. I am exploring your package. I've installed gpg, along with the caffe version of gpd. The gpd package tutorials work properly.

When I tried using the create_training_data launch files, it caused memory errors. On further investigation, I realized that class objects from gpg package were responsible.

For example, I tried a simple test file say test1.cpp // System

include

// Custom

include <gpg/point_list.h>

int main(int argc, char* argv[]) { PointList p(5, 1); return 0; }

and modified the cmakelists.txt as follows: add_executable(test1 src/tests/test1.cpp) target_link_libraries(test1 ${GENERATOR_LIB})

The above code causes segmentation faults, I checked and the constructor and destructors are called properly and I use catkin build to compile the package. I believe this happens when the eigen package variables are allocated memory. (In the case of the above constructor call). If I create an object with the default constructor eg: Pointlist p; which doesn't allocate any memory instead, the program exists properly.

The same happens for other objects like CloudCamera. Also one more observation, same/similar test cases don't cause any problems with gpg.

I would like to request your help. Please correct me if I am making any mistakes. Thank you for your time.

I fixed this by adding Eigen3::Eigen to the target link libraries.

I'm glad you fixed this. :+1: Would you mind elaborating on your fix (posting what you fixed exactly)?

As I described, the create training data launch file, led to segmentation faults, I tried the above simple testcase, just creating an object of PointList and it led to segmentation faults. I'm not sure why this occurs.
