Hi,

(I'm sorry for the very long reply below...)

Yes. So now I'm trying to install the alsa-gobject at first.

I checked my system and found it had these dependencies of the version below:

    glib-2.46.2
    gobject-introspection-1.46.0
    eudev-3.1.5

I did't seek for the gir files because I guessed that they would be made in the build of alsa-gobject or libhinawa.
Then I made a clone of the project of alsa-gobject;

    root@darkstar:/tmp# git clone https://github.com/alsa-project/alsa-gobject.git

and I moved into the directory and setup:

    root@darkstar:/tmp/alsa-gobject# meson . build

Meson gave me the message below, and I guessed the setup was done well.
(Because there wasn't any "No" nor "Error".)

    Could not rebuild /tmp/alsa-gobject/build

I tried to build as well, but get another error again.

    root@darkstar:/tmp/alsa-gobject/build# meson build

    ERROR: Neither directory contains a build file meson.build.

There was't meson.build file actually:

    root@darkstar:/tmp/alsa-gobject/build# ls
    build.ninja            doc/         meson-logs/     meson-uninstalled/  tests/
    compile_commands.json  meson-info/  meson-private/  src/

I'm ashamed to say I have no idea where I went wrong in the above steps.
But I would appreciate any help or suggestion to resolve these errors.

Thank you for the suggestion and offer. But I'd like to continue in this thread because I guess the above is perhaps only a  newbie's careless mistake and not development-related issue.
