NASM linker


I have set up a small environment for writing and testing assembly programs. I use shortcuts through aliases in ".bashrc".

The problem I have is that when assemble j1.asm and type:
[rene@lt cgi-bin]$ n ;line 3
[rene@lt cgi-bin]$ l ;line 4
I get a message:
ld: try.o: No such file: No such file or directory
because the previous commands were:
[rene@lt cgi-bin]$ nn ;line 11
[rene@lt cgi-bin]$ ld ;line 12
and try.o has been deleted.
(Why does the linker look for a file not included in the command?)

I have these aliases: (excluding the line number that's only there for clarity)
1 alias c="cd /var/www/cgi-bin"
2 alias j="cd /var/nobla/j1"
3 alias n="nasm -f elf j1.asm"
4 alias l="ld -s -o j1 j1.o"
5 alias s="strace ./j1"
6 alias e="emacs /var/files/memb"
7 alias d="ls -la /var/files/memb"
8 alias r="rm /var/files/memb"
9 alias t="touch /var/files/memb"
10 alias j1="/var/www/cgi-bin/j1"
11 alias nn="nasm -f elf try.asm"
12 alias ld="ld -s -o j1 try.o"

Could anyone help me solve this problem? Even rebooting doesn't fix it.

Thank you for your help.

Hi rblampain,

You've told bash that

l="ld -s -o j1 j1.o"

and that

ld="ld -s -o j1 try.o".

I don't know much about how bash figures aliases out, but I would say that "l" is resolving to:

ld -s -o j1 try.o -s -o j1 j1.o

Hope that helps.

Thanks to sind for the tip, it seems the linker was confused by " l" and "ld". I renamed "ld" as "y" and everything works finenow.
