i'm very new in assembly (nasm x86_64), and i run into a problem while i tried to use gdb, which says "no debugging symbols found" after assembling with -g -F dwarf options. I know that the problem can be caused by using .txt instead of .text, but i have corrected it and it didn't really help. I tried to google it, but i haven't found a solution. My .asm and makefile are on the screenshot. P.S. sorry my poor english.

Your linking command ld ‑m elf_x86_64 ‑s $(source).o ‑o $(source) will remove the generated DWARF debugging information. ‑s is short for ‑‑strip‑all. Remove this flag for a debuggable executable.

If you wanted to keep just the debugging information, call strip(1) with ‑‑only‑keep‑debug after the linking step.
