External assembler NASM - how to get debug info integrated
lazarus / 12-Debugger

Hi all,

After reading the NASM (and some other) documentation it might be that
I am asking for the impossible - but maybe I misunderstood and it is
possible.

Environment: FPC 3.0.0 + Lazarus 1.6.0 on Win7 (64 bit)

I am using NASM for external assembler routines that I link into a
Pascal framework. All working fine but as I have to use the output
format win64 on NASM (which is converted to COFF) it looks like there
is no way to integrate debug info into the external object file
produced. This means that I am not able to single-step through the
assembler routines like I used to under Linux with elf64 / dwarf. I
use

> NASM -f win64 LongArith.asm

to produce the object file and then refering to individual functions
in the Pascal framework via

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$link
LongArith.obj}...function abc( ... some parameters ...
):QWORD;register;external name 'abc'; 
Is it really not possible to integrate debug Information or did I miss
something?

Kind regards,
MathMan

try executing:
Code: Bash  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i nasm -hand
