If your program has in it an fopen or open statement, it means it will be using a data file at some point in the program. If this is so, then gdb also needs to know the name of such a data file. When you type run in gdb to run your program, you must also supply the actual names of such data files:

Most gdb commands have a single-letter equivalent consisting of the first letter of the command. Instead of entering the command run, you can enter just r. For quit, you can enter the letter q, for print just p, and for next the letter n. The gdb commands are listed in Table 3. Table 3: The: gdb Symbolic Debugger Command Description run quit Run the program. Quit gdb.

Running Programs in gdb r q
Running Programs in gdb Displaying Variables and Arguments p var p &var set var = value where
Table 3: The: gdb Symbolic Debugger Command Description
print var print &var
Display the contents of a variable. Display the address of a variable. Assign a value to a variable during the gdb session. Display a stack trace showing a sequence of function calls with function names and their arguments.
info locals Displaying Lines l linenum l func l num,num Stepping and Continuing Execution n next list linenum list func list num,num
Display defined variables and arguments. Display lines beginning with the specified line number. Display lines in a function. Display a range of lines.
Single-step execution line by line, executing the current line and displaying the next line to be executed. Single-step execution line by line, executing the current line and displaying the next line to be executed. Continue execution of the program.
step
c Setting and Deleting Breakpoints b
cont
break break line break func info break
Set breakpoint at current line. Set breakpoint at specified line. Set breakpoint at first line in the specified function. List all breakpoints. Delete breakpoints. You need to specify the number of the breakpoint. Delete all breakpoints.
d num
delete num delete
You display the contents of a variable using the print command. Enter the word print followed by the variable name. In the next example, the user displays the contents of the count variable:
(gdb) print count
With the where command, you can display the function names and arguments of the functions that have been called at any point in your program. In the next example, the user is currently in the calc function. Entering the where command displays the functions main, as well as calc and its arguments.
(gdb) where #3 calc(newcost = 2.0) at calc.c:25 #1 main () at main.c:19 #2 0x8000455 in ___crt_dummy__ ()
You can obtain a listing of all the variables and arguments defined in a function. The info locals command will display variable and argument values currently defined. In the next example, the user displays the defined variables:
(gdb) info locals cost = 2 name = "Richard\000\000" count = 10 count2 = 10 nameptr = 0x8000570 "petersen" countptr = (int *) 0xbffffde8
You can set breakpoints in your program using the break command. When you reach a breakpoint, your program will stop. You can then step through your program line by line using the next or step command. When you wish, you can advance to the next breakpoint by using the cont command.
Programming Tools
Many tools are available to help you prepare and organize your source code. The indent utility will indent the braces used for blocks in a consistent format, making the code easier to read. cproto generates a list of function declarations for all your defined functions for use in header files. f2c and p2c can translate Fortran and Pascal programs into C programs. xwpe is an X Windows programming environment similar to Turbo C. Many more tools are also available. Once you have finished developing your software, you may then want to distribute it to others. Ordinarily, you would pack your program into a tar archive file. People would then download the file and unpack it. You would have to have included detailed instructions on how to install it and where to place any supporting documentation and libraries. If you were distributing the source code, users would have to figure out how to adapt the source code to their systems. There are any number of variations that may stop compilation of a program. The Red Hat Package Manager (RPM) and Autoconf are designed to automate these tasks. Autoconf is used to automatically configure source code to a given system. The Red Hat Package Manager will automatically install software on a system in the designated directories, along with any documentation, libraries, or support programs. Both have very complex and powerful capabilities, making them able to handle the most complex programs. Several Linux distributions like Red Hat and Caldera support RPM packages.
