Library:: open error - code 126

[chip5441]

Trying to open a DLL by full path wrapped in OsStr on windows 10. But error code 126 / The specified module could not be found, raised.

When passing path directly to open function, it works!?

Hi! Thank you for your report. I am not sure if I got you correctly. I understand that you do something like this:

Library::open(path)

In the first case you use OsStr and it works, in the second case you use normal &str and it does not work?

The only explanation that comes to my mind is a problem with encoding string that is the argument to this function. Try to debug your code by printing out your argument and a conversion of str to OsStr. Something like this:

let your_str: &OsStr = ...<whatever>
let normal_str: &str = "c:\the\full\path.dll"; //this is the path that works.
let normal_str_converted: & OsStr = normal_str.as_ref();
println!("your={:?}, normal={:?}, converted={:?}", your_str, normal_str, normal_str_converted);

If your argument and converted are equal, then there is no reason for the library to fail. In this case please paste here your simplified code and I will try to fix this. But I suspect that you simply pass an invalid argument to the Library::open() function and this is why it does not work.

Regards!

@chip5441 Any updates about the issue? Do you still have the problem?

No response for two weeks, closing because it was probably just a problem caused by providing invalid string to the library.
