Mixing C and Assembly. `Hello World` on 64-bit Linux

Question

Based on this tutorial, I am trying to write Hello World to the console on 64 bit Linux. Compilation raises no errors, but I get no text on console either. I don\'t

Answer 1

Okay, so my code had two mistakes:

1) I named my as function 'write' that is common c name and i needed to rename it.

2) in function name, i shouldn't put underscores.

Proper code:

writehello.s

.data
SYSREAD = 0
SYSWRITE = 1
SYSEXIT = 60
STDOUT = 1
STDIN = 0
EXIT_SUCCESS = 0

message: .ascii "Hello, world!\n"
message_len =  .-message

.text
#.global main
#main:
#call write
#movq $SYSEXIT, %rax
#movq $EXIT_SUCCESS, %rdi
#syscall

#********
.global writehello
writehello:
pushq %rbp
movq %rsp, %rbp
movq $SYSWRITE, %rax
movq $STDOUT, %rdi
movq $message, %rsi
movq $message_len, %rdx
syscall
popq %rbp
ret

main.c

extern void writehello(void);
int main (int argc, char **argv)
{
    writehello();
    return 0;
}

Compilation stays as is :) Thanks to everyone that helped!
