Compiler Options and Flags

Compiler Full warnings Warnings as Errors Disabling a particular warning (#n)
gcc -W -Wall -Werror
MIPS Pro -fullwarn -w2
icc -Wall -w2 -Wcheck -Werror -wd(#n)
bcc32 -g1 -w-(#n)
xlC -qflag=w:w or -qlanglv=ansi
cl /W4 /WX /Wd(#n)
aCC +w +We +Warg1[,arg2,..argn]
  • More platform specific information can be found in ROSETTA STONE platforms table (Mostly for system administrators)

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":

#!/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}"

Then one may debug a test like this:

gdbrun /path/to/myexe --some-arg --some-other-arg

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
