On "current" macos there is a renamex_np function in libsystem_kernel, but none of the libsystem_kernel that I have in /nix/store-*-Libsystem-osx-* have it. Therefore, I have a configure script that fails to detect the function when build from stdenv. Any idea what I should do?

Nixpkgs uses an old macOS stdlib, because the source code for the newer ones hasn't been fully released (yet?)

There are some hacks you can do to impurely use the system one
<matthewbauer>
Yeah that was added in 10.12
<matthewbauer>
There should be a configure flag you can pass to disable it
<matthewbauer>
ac_cv_func_renamex_np_works=no should do it iirc

matthewbauer: OK I see. I will work around in with a patch. Thank you for the explanations.
