error: failed to run custom build command for alsa-sys v0.1.2

[GopherJ]

There is an error when it compiles alsa-sys

[thiolliere]

It may be because it needs development files.

on fedora it is alsa-lib-devel I think,
on debian libalsaplayer-dev maybe.

@thiolliere Hello, thanks for your reply. I still got this error:

process didn't exit successfully: `/home/cheng/Project/Rust/rodio/examples/mp3/target/debug/build/alsa-sys-89668916c5ee996e/build-script-build` (exit code: 101)

Ok, you may want to find alsa.pc using find /usr -name alsa.pc
If you can't find anything you probably miss the right alsa dev package.

For me it return /usr/lib64/pkgconfig/alsa.pc and /usr/lib/pkgconfig/alsa.pc

If it does exist it is surprising that pkgconfig don't find it.
But still you should be able to fix it using export PKG_CONFIG...=/usr/../pkgconfig or adding to the variable if it is not empty
Or otherwise reboot stuff maybe pkgconfig doesn't find it yet and must update its cache or something I don't know

I failed to find alsa.pc, it's strange...before that I've installed libalsaplayer-dev.

[thiolliere]

yes indeed I just find out on debian alsa dev files seems to be in package libasound2-dev instead

[GopherJ]

Thank you very much! It works well after installed libasound2-dev!

Had the same problem. This should probably be documented in the README.md.

Something like this :

## Dependencies
This crate requires `libasound2-dev` on Debian and derivatives (Ubuntu, Pop OS, ...).

In Void Linux, install the following
alsa-lib
alsa-firmware
alsa-lib-devel
I am not quite sure which one exactly solved my problem, but it was solved anyway

[vmontes]

In Void Linux, install the following alsa-lib alsa-firmware alsa-lib-devel I am not quite sure which one exactly solved my problem, but it was solved anyway

Thanks, this worked for my Fedora (using dnf)

It should be the last one
