Maybe you are missing libclang in your PC?
sudo apt-get install libclang or something simillar

[liyimeng]

tried, no help

[hohaidang]

Maybe you can try
export LIBCLANG_PATH="-clang-17.0.6-lib/lib"
for example
export LIBCLANG_PATH=/nix/store/92db16g3bi4fxwafskysvpsfbpsi1vkw-clang-17.0.6-lib/lib

[liyimeng]

will give it a try

[yodaldevoid]

I am also seeing this under NixOS. I have tried to export LIBCLANG_PATH, to no avail.

What has worked is forcing the runtime feature by adding an (unused) dependency of bindgen = { version = "0.69", features = ["runtime"] } and allowing cargo to merge the features.

[imobachgs]

I find the same (or at least a similar) problem if I combine pam 0.8 and libpwquality. It works fine if I pin pam to version 0.7.0. Using pam 0.8 alone builds fine.

Just in case it is useful, this is the backtrace:
