Is there any way to tell Rust where to look for my static library? Example code
#[link(name = "/this/is/the/path/libfoo.a", kind = "static")]
If not, what config change can I make or what folder do I place my library in so that I can use it?
rustc invokes the system linker which looks for all libraries specified in #[link(...)] in library directories. There are usually several default library directories (like /lib and /usr/lib on Linux), and more can be specified via linker flags (rustc accepts -L options which it then passes through to the linker).
If you invoke rustc directly, you can use the -L option to add additional library directories which will be then passed through to the linker. If you use Cargo, however, you've got a few more options:
Cargo adds the /target/<profile>/deps directory as a library source directory (before 1.82).
You can use cargo rustc
cargo rustc -- -L /path/to/library/directory
You can specify the RUSTFLAGS environment variable:
RUSTFLAGS='-L /path/to/library/directory' cargo build
You can use a build script to output more linker options
println!("cargo:rustc-link-lib=static=foo");
println!("cargo:rustc-link-search=native=/path/to/foo");
The easiest way for you, I think, is to add a custom build script which will copy or create a symlink to your library in the corresponding /target/<profile>/deps directory.
