I am not a programmer, I just wanted to compile fd for AIX.
The compilation ended up with errors see attachment.
Am I making a mistake somewhere? Is there any way to fix it?

That looks to me like the nix crate doesn't support AIX.

And yes, it isn't listed as a supported target on their readme

[tavianator]

It's probably possible to make nix an optional dependency. But is there an easy way to test builds on AIX? Otherwise we're kinda programming blind

[arozehnal]

I understand that there is a problem with the availability of AIX for testing. But if it is about compilation and verification of functionality, I offer my help.
