undefined reference to `PointMatcher<float>::DataPoints::getDescriptorRowViewByName

[Masoumeh]

hi Mattieu,

I have also another issue on my own laptop, after doing catkin_make, i received the following error:
error_while_catkin_make.png

according to the error, i tought that it is because of libpointmatcher, so i tried to install it, but in one part i recived the following error:
masoumeh@masoumeh-ThinkPad-T490s:~/Libraries/libpointmatcher/build$ cmake -D CMAKE_BUILD_TYPE=RelWithDebInfo ${SRC_DIR}

Thanks in advance, and sorry for asking lots of questions

undefined reference errors are because the library may be not linked properly to libpointmatcher.

For the libpointmatcher error, I saw they added recently a python binding api, you may try to build without that option if possible.
