| == Debugging Tips ==
| |
| | |
| === The gdbrun Script for UNIX-like Platforms ===
| |
| | |
| The following is an extremely useful script that will run any command line in a gdb debugger. Put this text in an executable file called "gdbrun":
| |
| | |
| <pre><nowiki>
| |
| #!/bin/sh
| |
| | |
| extra_text=""
| |
| if [ "$1" == "--break-main" ]; then
| |
| extra_text="break main"
| |
| shift
| |
| fi
| |
| | |
| EXEC="$1"
| |
| | |
| shift
| |
| | |
| run_text="run"
| |
| for a in "$@"; do
| |
| run_text="${run_text} \"$a\""
| |
| done
| |
| | |
| TMPFILE=/tmp/gdbrun.$$.$#.tmp
| |
| cat > ${TMPFILE} <<EOF
| |
| ${extra_text}
| |
| ${run_text}
| |
| EOF
| |
| | |
| gdb -x ${TMPFILE} "${EXEC}"
| |
| rm -f "${TMPFILE}"
| |
| | |
| </nowiki></pre>
| |
| | |
| Then one may debug a test like this:
| |
| | |
| <pre><nowiki>
| |
| gdbrun /path/to/myexe --some-arg --some-other-arg
| |
| </nowiki></pre>
| |
| | |
| Notes about this script:
| |
| * It supports spaces in argument names (note the for loop)
| |
| * Takes extra argument --break-main, which causes the program to stop once all the libraries are loaded
| |
| * It always run debugger, even when program exits normally
| |
| * Cannot be used with MPI or any other system that runs your program from a shell script
