rustc --explain E0425
An unresolved name was used.

Erroneous code examples:

something_that_doesnt_exist::foo;
// error: unresolved name something_that_doesnt_exist::foo

// or:

trait Foo {
fn bar() {
Self; // error: unresolved name Self
}
}

// or:

let x = unknown_variable; // error: unresolved name unknown_variable

Please verify that the name wasn't misspelled and ensure that the
identifier being referred to is valid for the given situation. Example:

enum something_that_does_exist {
Foo,
}

Your error is because Windows doesn’t have the mincore syscall. Sorry, ntcrack doesn’t support windows right now.

Ok no problems,

So i try on my mac m1 and this time i succed to install (with a warning) it but i still have an issue when i want to lauch the tool.

When i build it i have this warning :

cargo build --release
warning: field is never read: pages
--> src/main.rs:163:5
|
163 | pages: usize,
| ^^^^^^^^^^^^
|
= note: #[warn(dead_code)] on by default

Then i try to lauch the tools and i have an issue :

./target/release/ntcrack files/some_ntds.ntds files/some_passsword.txt
thread 'main' panicked at 'called Result::unwrap() on an Err value: OddLength', src/main.rs:128:69
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

I will try on my laptop toomorow on ubuntu 22 and see if it's work

You need to pass it a list of raw hashes [1], so strip them out of that ntds with grep -oi "[a-f0-9]\{32\}" files/some_ntds.ntds > some_ntds.hashes

[1] mentioned at top of docs https://github.com/sensepost/ntcrack#invocation
