[ros-users] segmentation fault using ROS

[ibwood]

Hi everyone,

Upon trying to run a node, the file "rosrun" came up with a segmentation
fault: Here is my file..
It said the error was in line 35 (last line) with "$exepath "$@"":


#!/bin/bash
if [ $# -lt 2 ]; then
  echo "Usage: rosrun PACKAGE EXECUTABLE [ARGS]"
  echo "  rosrun will locate PACKAGE and try to find"
  echo "  an executable named EXECUTABLE in the PACKAGE tree."
  echo "  If it finds it, it will run it with ARGS."
  exit 1
fi
pkgdir=`${ROS_ROOT}/bin/rospack find $1` || exit 2
# The -perm /mode usage is not available in find on the Mac
#exepathlist=(`find $pkgdir -name $2 -type f -perm /u+x,g+x,o+x`)
exepathlist=(`find $pkgdir -name $2 -type f  -perm +111 ! -regex
".*$pkgdir\/build\/.*"`)
if [[ ${#exepathlist[@]} == 0 ]] ; then
    echo "[rosrun] Couldn't find executable named $2 below $pkgdir"
    nonexepathlist=(`find $pkgdir -name $2`)
    if [[ ${#nonexepathlist[@]} != 0 ]] ; then
      echo "[rosrun] Found the following, but they're either not files, "
      echo "[rosrun] or not executable:"
      for p in ${nonexepathlist[@]}; do
        echo "[rosrun]   ${p}"
      done
    fi
    exit 3
elif [[ ${#exepathlist[@]} -gt 1 ]] ; then
    echo "[rosrun] You have chosen a non-unique executable, please pick one
of the following:"
    select opt in ${exepathlist[@]}; do
        exepath=$opt
        break
    done
else
    exepath=${exepathlist[0]}
fi
shift
shift
$exepath "$@"


What is the issue here?

Thanks,
Ian
