Hey @Orca-bit, did you find a solution to this? I'm having the same issue with trying to cross-compile it to x86_64-unknown-linux-musl like yourself.

[benesch]

When cross-compiling, there are various configure tests that you'll need to provide the results of, since the tests can't be run automatically. In this case, you should set the krb5_cv_attr_constructor_destructor to yes or no based on whether your target system supports constructor/destructor attributes.

You may find the code and discussion in https://github.com/MaterializeInc/rust-krb5-src/pull/24 helpful as well.

I'm going to close this out, since this is is working as intended from the perspective of this crate!
