ai::* not found on build with feature asio
I'm using the following code:
pub fn initialize_host() -> cpal::host {
let host;
#[cfg(target_os = "windows")]
{
host = cpal::host_from_id(cpal::HostId::Asio).expect("failed to initialise ASIO host");
}
host
}
With this dependecy:
[dependencies]
cpal = { version = "0.15.2", features = ["asio"] }
I added the sdk to the path:
$env:CPAL_ASIO_DIR
C:\Users\<my_path>\driver\windows\asiosdk_2.3.3_2019-06-14

error: could not compile `asio-sys` due to 14 previous errors
I think i have followed carefully all instructions and I don't know what else can I check from here. I cleaned multiple times the build.
Environment:
Windows 10
cargo 1.69.0 (6e9a83356 2023-04-12)
Any hint on how can I debug this? I can not even compile the basic example. The environment variables configured, and the sdk can not be downloaded in older versions.,.
I finally was able to found out what is going on. It seems the current crate published in crate.io does not correspond with the code that is in the git repository with version 0.15.2. Therefore when you just use the dependency it will not include 718d49ef5ee3714482051c188fe274533fa2b2b9 and therefore not build.
I was able to build using the git repository as dependency as a temporary patch:
cpal = { git = "https://github.com/RustAudio/cpal.git", features = ["asio"] }

Ran into the same problem, thanks for the workaround :)

For those who ran into the same problem, but also has dependencies that also depends on cpal (like rodio), use this instead:
[patch.crates-io]
cpal = { git = "https://github.com/RustAudio/cpal.git", branch = "master", commit = "f51589c" }
I was having a similar issue, it is great that there is a work around and it worked for me also. Is there any plan to fix this in the stable release soon? It would have been nice because it is not possible to publish a crate with git dependencies.
thank you all so much for finding a workaround. Would this be fixed by publishing a new release?
