Error while building ros package: Kannala

[shashankyld]

The error message suggests that there are warnings and errors related to the initialization order of some variables in the KannalaBrandt8 class definition.

The warning message indicates that the precision variable will be initialized after the mvLappingArea variable, which may result in unexpected behavior during runtime.

I get this same issue

Hi @shashankyld and @SaundersJE97 , sorry for the late reply.

Based on the error message, I don't think the error is about the KannalaBrandt8 class or this ROS wrapper but because your computer ran out of memory while building the packages (see the fatal error line).

Perhaps you can follow the guide here mlpack/mlpack#2775, basically you can try to reduce the number of cores used (build with make -j1), increase the size of your swap partition, or both.
