New comment by tranzystorek-io on void-packages repository https://github.com/void-linux/void-packages/issues/34889#issuecomment-1046095433 Comment: From https://github.com/google/cargo-raze/issues/114#issuecomment-547080315: > (Nitty gritty aside: It seem the way this works is the autocfg library tries to run rustc over a file containing the single "extern $some_crate", and identifies whether or not that compiles) Maybe building a file like: ```rust extern crate std; ``` on the failing targets could point to the cause of this problem?
