Segmentation fault after ./segmentation_test

[amiltonwong]

Hi, @trungtpham ,

After make install the package, I test it as follows and got the Segmentation fault error:

root@milton-All-Series:/data/code2/cpf_segmentation/build# ./segmentation_test ../test_data/tum_small.pcd
Loading pointcloud
Number of points: 749580
Number of points after filtered 733102
Segmentation fault (core dumped)

Any suggestions?

Thx~

Hi, It is hard to see why you've got segmentation fault error. Did you try multiple time and still got the same error? Could you please try different smaller pcd data?

Cheers, Trung

@Hi, @trungtpham ,

Still the same segmentation fault error. Would it be pcl library conflict in my system? I have both pcl 1.7 and 1.8.

$ pkg-config --list-all | grep pcl_segmentation
pcl_segmentation-1.7             pcl_segmentation - Point cloud segmentation library
pcl_segmentation-1.8             pcl_segmentation - Point cloud segmentation library

This might cause the issue. Having 1.7 and 1.8 at the same time is problematic because sometimes it is not defined which lib the code is linked to. One option is to set the minimum version to 1.8 in the cmake file. A safer way is to have both versions installed in the /opt folder away from the standard paths which is /usr /local. Than you can set the LD_Library path in your..bashrc as needed.

@amiltonwong @trungtpham @MarkusEich
Have you solved this error?

Number of points after filtered 733102 Number of supervoxels: 5214 Super-voxel segmentation takes: 6449.05ms cpf_2: /usr/include/eigen3/Eigen/src/Core/CommaInitializer.h:95: Eigen::CommaInitializer<MatrixType>::~CommaInitializer() [with XprType = Eigen::Block<Eigen::Matrix<float, -1, -1>, 1, -1, false>]: Assertion `(m_row+m_currentBlockRows) == m_xpr.rows() && m_col == m_xpr.cols() && "Too few coefficients passed to comma initializer (operator<<)"' failed.

I get the above error, any suggestions? Thank you very much!

Hi guys, @amiltonwong, @rrkmiao, i got this error and i solved fixing the file: segmentation/config.h, on method Config& operator=(const Config& config), at the end, add line "return *this;", to return the reference.

Hope this help.

Have you resolved the problem? I meet the problem too.

I tried your method, but it seems no use.

For me it worked. Are you sure you recompiled the code? To "apply" the changes you would have to run "make install" again.
