I keep getting this error mesage when trying to add a breakpoint in gdb.

I've used these commands to compile:

gcc -g main.c utmpib2.c -o main.o
and also:
cc -g main.c utmpib2.c -o main.o

and I still get that error message.

I've used these commands to compile:

and:
cc -g main.c utmpib2.c -o main.o
and also:
g++ -g main.c utmpib2.c -o main.o

I also tried "-ggdb" instead of "-g" and I still get that error message.

I then execute gdb:

$gdb

In gdb:

(gdb)exec-file main.o
(gdb)break 59
No symbol table is loaded. Use the "file" command.
