How can I use gdb with an "exe" created by fasm ?

I have a very simple .asm file, and I create the .exe using fasm program.asm.

Running gdb program.exe, and I see "no debugging symbols found".

So what am I missing ?


I can debug a c program if compiled using "-g" option of "gcc".
But is there an equivalent with fasm ?


This is my gdb :
C:\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin\gdb.exe


Thanks !

Thou have to produce program as format binary - so thou could build any debug info as thou want (in fasm all debug information programmer should produce manualy, so thou previously should know format of thour debug information to produce it properly).
Or use some debugger not dependant from absence of debugging symbols (IDA PRO for ex.).

IIRC you don't need symbols to debug with gdb. The symbols can help but are not a requirement.

So go ahead and debug, it should still work, just without any named symbols.

However if you are using Windows then OllyDbg might be a more friendly choice.
