@ogranada Hi, maybe https://github.com/1wilkens/pam/pull/24 would help?

I believe there is presently a compatibility issue with non-Linux systems.

@ogranada Hi, maybe #24 would help?

I believe there is presently a compatibility issue with non-Linux systems.

How can I help to test the packages?

[ogranada]

I just built the package pam-sys@v1.0.0-alpha3 changing the

     .default_macro_constant_type(bindgen::MacroTypeVariation::Signed)

By

     .default_macro_constant_type(bindgen::MacroTypeVariation::Unsigned)

and the build process happened properly.

Sorry for the late reply! I was figuring out some details in pam-sys and pam was left in a weird state. I pushed some changes to pam-sys that hopefully improve non-Linux compatibility and changed the macro here to properly handle the constants now being i32. I have not cut a release here yet, but feel free to test! Some other things are still in flux, but the build should pass with the latest pam-sys now :)

[1wilkens]

This should be fixed now.
