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 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

gdb: "No symbol table is loaded"

You have to add extra parameter -g, which generates source level debug information. It will look like:

gcc -g prog.c

After that you can use gdb in common way.
