Línea de trabajo

Start with the reported hello_world.c and generated hello_world.v, then reproduce the errors using the listed V, c2v, and GCC versions. Compare the translated output with the terminal errors and the results from the sorting_algorithms and calculate_pi examples. Done means identifying the translation cause and confirming that the affected C examples run without the reported errors.

Descripción

There were 3 files I translated, all exhibits similar characteristics: all translated successfully but lots of errors when running the file.
Starting from sorting_algorithms (bubble sort, heap sort, etc)
Then I pull out a simpler C file: calculate_pi
Lastly I tried a hello_world C file --> translated successfully and some errors, but after manual fixing here and there I got it to run.

here is my hello_world.c

#include <stdio.h>

int main(void)
{
    const char lang[] = "C";
    const char object[] = "World";
    printf("Hello, %s %s!\n", lang, object);
    
    return 0;
}

below is the translated hello_world.v

fn main()  {
	lang := c'C'
	object := c'World'
	C.printf(c'Hello, %s %s!\n', lang, object)
	return 
}

below is the error messages I got when trying to run the hello_world.v

as you can see the errors are minor typos...but why these errors appeared in the first place?
I mean in the Youtube demo, you translated the whole DOOM game...why translating just a hello_world script ended up with these errors?

For the other files I just don't bother anymore coz it's a lot and lots of minor errors that needed fixing.
Also looking at there are some open issues relating to the same error...should we expect a fix sometime soon?
