Cannot convert C file to V

[Unicorn7141]

I tried following the demo, and copied the primes.c file to a file called main.c which has the following code:

#include <stdio.h>
#include <stdbool.h>

_Bool is_prime(int num) {
    for (int i = 2; i <= num / 2; i++) {
        if (num % i == 0) return false;
    }

    return true;
}

int main() {
    for (int i = 1; i < 100; i++) {
        if (is_prime(i)) {
            printf("%i\n", i);
        }
    }

    return 0;
}

I validated the code is working by running

gcc main.c -o run.exe
run

and it worked as exxpected.

Then I tried running v translate main.c and got the following error:

C to V translator 0.3.1
  translating main.c          ... 
The file main.c could not be parsed as a C source file.
C2V command: "C:\Users\Unicorn\.vmodules\c2v\c2v.exe" "main.c"
C2V failed to translate the C files. Please report it via GitHub.

I don't know if this is Windows specific, the version of clang you have, or what, but it works correctly here, on Linux, using V 0.3.3 2179db3 and clang version 15.0.7:

$ vi main.c
[jalon@7950x ~]$ gcc main.c -o run

So... which version of clang do you have? If you don't have the one from https:\\winlibs.com, I recommend uninstalling what you have now, and getting that one.

I downloaded MinGW64 and it came with clang...

Everyone using V on Windows has had much better luck with the gcc/clang package from https://winlibs.com - it is a much more up-to-date package than the one from mingw, usually.

This is exactly what I downloaded....

I faced the same issue on Windows 10 trying to run v translate on an example from the docs. I already had gcc from MinGW package that works ok with compiling C files, but not with c2v. Then I installed clang with llvm package, and now c2v works without errors.

[TimmieTudor]

Same issue, also on Windows. By the way I also downloaded clang from winlibs.

clang with llvm package

Could you share the link for this, please?

[JalonSolov]

Look on https://winlibs.com - you have a choice of downloading gcc either WITH, or WITHOUT clang/llvm/ldb/lldb

Just choose one of the links to the left, instead of the right (after the text about "without...").

Up to version 14.1.0 there, now.
