Hi everyone, I'm having a problem with gazebo shutting down instantly whenever I try to launch it. It displays this error after shutting down: [gazebo-2] process has died [pid 18980, exit code -11]. log files: /home/yglee/.ros/log/ada4f184-8850-11df-899a-00236c960005/gazebo-2*.log I have remade the gazebo, ogre, and pr2 files and dependencies seem to be alright. I also have libfreeimage3, libfreeimage-dev,libfreeimage3-dbg installed. There is a ticket for this kind of error listed on trac: https://code.ros.org/trac/ros-pkg/changeset/26037 I made the suggested revisions in the Makefile and ran "make" but it leads to another error: make: *** No rule to make target `gazebo_patch2.diff', needed by `patched'. Stop. I would appreciate any insight into fixing these bugs. Thank you in advance. ~Grace Lee
