Project doesn't build, linker error
I have a minimal project which fails to build when the call to ctx.connect() is added to the code. This is my src/main.rs:
extern crate soundio;
fn main() -> Result<(), String> {
let mut ctx = soundio::Context::new();
ctx.set_app_name("mytest");
ctx.connect()?; // builds when this line is removed
Ok(())
}
And Cargo.toml:
[package]
name = "mytest"
version = "0.1.0"
authors = ["xrudelis"]
[dependencies]
soundio = "0.2.1"
The output of cargo build ends like this, after many similar errors:
/usr/bin/ld: /home/xrudelis/mytest/target/debug/deps/liblibsoundio_sys-28f43b51c120f186.rlib(alsa.c.o): in function `instream_pause_alsa':

I've attached the full output here of running cargo build --verbose on this project. Tested with Rust 1.40.0 and also a newer nightly. I am not very familiar with the rust compiler / linker but I have verified that I can build C projects with libsoundio just fine on this machine.
I ran into a similar, if not the exact same, problem.
Here is what I did:
$ cd /tmp/
$ git clone https://github.com/RamiHg/soundio-rs

I'm running a freshly updated Archlinux.
The soundio library itself in libsoundio-sys/libsoundio compiles fine for me so it's likely not a dependencie issue.
It rather looks like the linker pass for den final list_devices binary is missing references to the pulseaudio, alsa and jack libraries.
I did some digging: libsoundio-sys wraps a statically linked version of libsoundio, that lives somewhere in the target folder: target/debug/build/libsoundio-sys-56755798501abf76/out/lib/libsoundio.a.
If we poke it with nm we get a bunch of undefined like:
U snd_card_next
U snd_config_update
U snd_config_update_free_global
U snd_ctl_card_info
U snd_ctl_card_info_get_name
U snd_ctl_card_info_sizeof
U snd_ctl_close
U snd_ctl_open
U snd_ctl_pcm_info
U snd_ctl_pcm_next_device
U snd_device_name_free_hint
U snd_device_name_get_hint
U snd_device_name_hint
or
U jack_activate
U jack_client_close
U jack_client_open
U jack_connect
U jack_free
U jack_get_buffer_size
U jack_get_ports
U jack_get_sample_rate
U jack_on_shutdown
U jack_port_by_name
U jack_port_flags
U jack_port_get_buffer
w jack_port_get_latency_range
U jack_port_name
U jack_port_register
U jack_port_type
U jack_set_buffer_size_callb
Which are likely all of the symbols the linker complained about earlier. So while libsoundio-sys itself compiles fine, the resulting library is missing all the symbols for the underlying library. And that causes the linker to fail as soon as we want to link an actual binary against it.
It works for me after making the following changes.

Works for me. I ran into the same issue on my Raspberry Pi
That should work.
The other thing I ran into is that that linking against all three libraries means your binary will always depend all of those libraries even if your are just using pulse audio. In addition to that you have to have all of them installed for the linking to work. So a proper fix should also address that somehow.
I stopped using soundio-rs a few weeks ago, because I ran into some other unrelated problems further downstream in my project and decided to ditch platform independent sound for now. I switched to libpulse_simple_binding, which suits my usecase a little better.
