How to link the readline library to an object file?

Question

I'm trying to use the GNU readline library in a program written in FASM. This is my assembly code:

format elf64

public _start

extrn readline

section ".text" executable
_start:
    push prompt
    call readline
    jmp  _start

section ".data"
    prompt db ">> ", 0

Then I compile and link it as follows:

$ fasm test.asm
$ ld -lreadline test.o -o test

However when I try to execute ./test bash gives me the following error message:

bash: ./test: No such file or directory

The test executable is present in the directory. What's wrong? Am I not linking the libreadline library correctly?

This happened to me once when I was on a 64-bit system compiling code for 32-bit. You have to install some additional 32-bit development tools and libraries (like an appropriate variant of libc) so that 32-bit binaries can be recognized as executable as well.
