Trying to code in assembly with ubuntu, but it doesn't compile and an error keeps appearing
-1
I'm using Ubuntu 32bits to program in assembly. I used a simple code that we used in class to test it but when I do: gcc - g assembly.s -o assembly , an error appears. assembly.s is the name of the text editor with the code. I don't know what I'm doing wrong here, especially since this is what we did in our classes.
This is the error that keeps appearing:
/usr/lib/gcc/i686-linux-gnu/5/../../../i386-linux-gnu/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: error: ld returned 1 exit status
And my code is just this,
.data
var1: .long 125
var2: .long 32
.text
.globl main
main:
movl var1, %eax
movl va2, %ebx
ret
assembly ubuntu-16.04

Make sure there is no space between-andgalthough that would produce a different error. Also you have a typova2instead ofvar2but again, that would result in a different error.

Your code looks correct. Make sure this is the actual file you tried to assembly. Also make sure that you actually hit “save” in your text editor before assembly.

Builds just fine for me withgcc -g -m32 foo.s(after fixing theva2typo). Clearly neither the code nor your command (- gvs.-g) were copy/pasted accurately, so this isn't a Minimal, Complete, and Verifiable example of anything. With your code or your command, gcc gives different error messages.g: No such file or directoryorundefined reference to 'va2'

Make sure there is no space between
- and g although that would produce a different error. Also you have a typo va2 instead of var2 but again, that would result in a different error.– Jester
