Hi,
I wanted to debug a program. I am really having trouble setting up a breakpoint at a specific line.
The file is named prog2.c and I have compiled using gcc option.
i have attached a snapshot if somebody can figure out why i am getting the No symbol is loaded. can somebody help me? Please let me know the correct syntax for the break option at a particular line numbers

(gdb) gdb prog2
(gdb) break main
Breakpoint 1 at 0x8048432
(gdb) break prog2.c:10
No symbol table is loaded. Use the "file" command.
(gdb) file prog2.c
"/home2/hjc/prog2.c": not in executable format: File format not recognized
(gdb) file prog2
Reading symbols from /home2/hjc/prog2...(no debugging symbols found)...done.
(gdb) break prog2.c:10
No symbol table is loaded. Use the "file" command.

Include "-g" to add the extra information the debugger needs in order to set breakpoints. For example:'Hope that helps .. PSM

Thank u so much!! it sure did help...i checked under the option_name list. could not find any info on -g. what does the -g option stand for? thanks once again...i was tired of writing printf statements in the programs!!

Hi I am getting the same problem, I can not add -g at the time of compilation because It is a very big code which has a make file to compile.

Well, I had the same problem here and it was "solved" when I realise that I forgot to compile the program before debbuging. I just generated the files with the cmake but forget to compile using the make command.

Hope that helps you or someone else with a similar problem.
