== 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
