Debugging with gdb not showing line numbers
By weakestOsuPlayer_244, history, 4 years ago, In English

Hello everyone. I was trying to learn how GDB works and learn about debugging.

While trying to set breakpoint on main function I saw that it's not displaying the line number in decimal.

So I looked up a bit and found that one needs to include the -g flag while compiling the cpp file.

I did that and yet it doesn't show the line numbers in decimal. (Thereafter I tried to search this up but couldn't get the issue resolved)

My GDB version is 7.6.1 (probably latest for windows)

If someone can help me out with this it would be much appreciated.

UPD: Found out issue. Seems like compilation generates a separate file (a.out) and you have to run gdb on that file.

If your compiler generates a.out by default, then you ran gdb on wrong binary.

    Thanks a lot.. now it's working So it is always going to generate a.out for whatever cpp file I compile or is there a way to change this?
