I apologise in advance for asking a dev question on the public mailing list,
but this forum is the most visible for knowledgeable developers.
I'm having difficulties creating a working executable using GNU 'as' and
'ld'.
Sample "Hello World" in GNU assembler:
#file is called example.s
.section .data
output:
.asciz "Hello World\n"
.section .text
.globl main
main:
pushl $output
call printf
pushl $0
call exit
Using gcc, the assembly program compiles and runs without any errors.
(~/develop/example)> gcc -o example example.s
However, if I manually assemble and link the program, the executable doesn't
work.
(~/develop/example)> as -o example.o example.s
(~/develop/example)> ld -o example example.o -e main -lroot
(the -e main argument instructs linker to search for main instead of _start)
When executed, I get a segment violation error under Zeta 1.2.
Does anyone know how to manually compile / link the above example? Thanks
in advance.
