Hi guys,

I am using ros::package::getPath to resolve the path to a config file I am loading within my program. When I am starting the node using

rosrun node_pkg node

everything works just fine, but when I directly launch the generated executable in the devel directory, I immediately get a segmentation fault

can anybody explain this behavior?

#include <ros/package.h> 
std::string path = ros::package::getPath("x_common");

Thank you for your time!

While I am not answering the question, I am trying to provide additional information that may help someone with a similar problem or the original poster. The comments do not allow enough characters.

I sympathise, but ROS Answers is a single question, multiple answer Q&A platform, not a regular forum. Unfortunately it doesn't lend itself to this sort of interaction.

Posting a new question is akin to opening a new diagnostic session, and if your issue gets resolved and it turns out that the ..

.. solution is generic enough and applies to others as well, we can just close this one with an answer pointing to your issue.

If it turns out they are two different problems, then the two separate questions/posts apparently made sense, so nothing lost by having them.

Sorry. I changed my answer to provide additional detail. I believe this partially answer the question now....

The Boost hint is a nice one. Are you linking a different Boost version?
