The GNU Debugger ( GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, Assembly, C, C++, D, Fortran, Haskell, Go, Objective-C, OpenCL C, Modula-2, Pascal, Rust, [2] and partially others. [3] History.
When you run a program under GDB, you must first generate debugging information when you compile it. You may start GDB with its arguments, if any, in an environment of your choice. If you are doing native debugging, you may redirect your program’s input and output, debug an already running process, or kill a child process.
Compiling. To prepare your program for debugging with gdb, you must compile it with the -g flag. So, if your program is in a source file called memsim.c and you want to put the executable in the file memsim, then you would compile with the following command: gcc -g -o memsim memsim.c. Invoking and Quitting GDB.
