rust-cargo

Why does `cargo build` fail to run custom build command for `stdint v1.0.0`?

I'm trying to compile a keypad driver written in Rust by using cargo build, but I get a strange error message I can't find any information about:

╭─jacek@epica /import/valen/autoradio/libkeypad

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I'm afraid that the culprit is the missing gnu/stubs-32.h file, but I have no clue on where to get it. If it was a part of the Rust programming system, it would have been installed automatically, I suppose. And: Is that a 32-bit header? My workstation is using a 64-bit version of OpenSuSE 15.6.

Solution

  • OK, I found out that there is in fact a 32-bit Glibc developer package missing for whatever reason, so installing it helped:
