snd-firewire-ctl-services not building on cargo

[NakuMorita]

Greetings! Trying to install snd-firewire-digi00x-ctl-service using cargo install --runtime/digi00x, i have dependencies installed.

This is the error I'm having:

To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

I'm also having similar error when I'm building the snd-firewire-ctl-services folder using cargo build

Any advice?

Thank you in advance

Hi,

Thanks for the report. Would I ask you to run cargo build just under the repository? It it fails, we have any issue in build process.

Greetings! Trying to install snd-firewire-digi00x-ctl-service using cargo install --runtime/digi00x, i have dependencies installed.

Anyway, the command line is invalid, I think.

No reaction in a few weeks, so let me close the issue.

Hi @NakuMorita,

I can regenerate the issue after executing cargo update. I'm sorry to catch it up...

The issue of signal comes from changes in nix crate. The crate introduces crate features to enable/disable the signal function at 0.24 release. In the time, all of the features are enabled as a default. The crate also changed its policy of features; disables as a default. As a result, nix applications should indicate feature flags by their own.

I guess that you can find nix 0.27 or later in your Cargo.lock, while I still used old version of the crate. It is the cause of issue.

I pushed 30428313eacc33927125e7 to fix the issue. In my local, current master (d1602462) can be built with hinaw-rs v0.7.1 release.

Thanks for your report.
