Debugging in Linux/UNIX

Debugging run-time errors:

• recompile your code with "-g -C"
• enable cores

ulimit -c 10000000

This allows core with a maximum size of 10M.

• run your program
• run the debugger

gdb <executable> core

inside the debugger you can use the commands such as "where", "print", "up",... See man gdb.

The command

gdb -p pid#

allows one to see what a program is doing while it executes.
