Debuggers and Profilers
Debuggers To use a debugger, it is necessary to rebuild your code with the -g flag added. All object files must be removed anytime compiler flags change. If you have a Makefile run make clean if it is available. The program must then be run under the control of the debugger. For example, if you are using gdb, you run
gdb ./myexec Adding debugging flags generally disables any optimization flags you may have added, and can slow down the code. Please remember to recompile with -g removed once you have found your bugs.
Gnu Debugger (gdb) and Profiler (gprof) The Gnu Compiler Collection compilers are free, open-source tools.
