When using opteadm as a Git dependency in a project's Cargo.toml, we get linking errors. Things seem to work fine if the dependency is specified as a local, path-dependency. To reproduce, create a new binary:
With a Cargo.toml that looks like this:
[package]
name = "tst"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
opteadm = { git = "https://github.com/oxidecomputer/opte" }
I have the following minimal binary, in `src/main.rs:
fn main() {
let _ = opteadm::OpteAdm::open(opteadm::OpteAdm::DLD_CTL).unwrap();
}
Running the package's binary fails at link:
bnaecker@feldspar : ~/tst $ cargo +nightly run
Compiling tst v0.1.0 (/home/bnaecker/tst)
error: linking with `gcc` failed: exit status: 1
