Cargo keeps rebuilding winapi

help
1

Hello,
on one of my computers every time I'm running a project using winapi, cargo rebuilds it. Please see a minimal example:

$ cargo new test-winapi
     Created binary (application) `test-winapi` package

$ cd test-winapi/

$ cargo add winapi
    Updating crates.io index
      Adding winapi v0.3.9 to dependencies.
             Features:
             - accctrl
			(...)
             - xinput

$ cargo run
   Compiling winapi v0.3.9
   Compiling test-winapi v0.1.0 (D:\Users\msien\source\test-winapi)
    Finished dev [unoptimized + debuginfo] target(s) in 3.61s
     Running `target\debug\test-winapi.exe`
Hello, world!

$ cargo run
   Compiling winapi v0.3.9
   Compiling test-winapi v0.1.0 (D:\Users\msien\source\test-winapi)
    Finished dev [unoptimized + debuginfo] target(s) in 0.54s
     Running `target\debug\test-winapi.exe`
Hello, world!

I found out the problem is caused by the build_script_build wich after every execution changes it's modify time so it is always newer than the binaries it builds. So they're never up to date:

I looked into my configurations and environmet and didn't find anything special. It just happens on 1 machine (Win 11 rigth now). Dou you guys have an idea how to fix it?

Cheers,
Marty

I seem to have the exact same problem, also on a single machine, windows 11, but on another windows 11 machine it does work. Did you ever find a solution?

Nope. Buf after the clean installation of the OS everything works fine. (I did it for a different reason) One day or another someone will find the bug :slight_smile:
