abk1's scratched blog 3::AUDIO DIARY

さて先日、Ras Pi 3b+をroon bridgeにしたのだけど、これにmpd、upmpdcliをインストールする前に、まずは、かなり旧式になったRaspberry Pi B+で何かできないかと考えた。B+はいくつか残っていて、使えるものなら使いたい。
そんなことを考えたせいで、あれこれといじることになった。

以下、顛末の記録。
このエントリーは長い。やたら長い。
自分でもどうかと思うが、備忘録だからある程度仕方ない。

というわけで、mpdなど諸々のインストールをどうするか。
mpd
https://www.musicpd.org/download.html

https://www.musicpd.org/news/2023/12/mpd-0-23-15-released/
mesonが要る。
https://www.musicpd.org/news/2018/10/mpd-0-20-23-released/
こっちは要らない。

libmpdclient https://www.musicpd.org/news/2023/12/libmpdclient-2-22-released/
こっちはmesonが要る。
https://www.musicpd.org/news/2021/11/libmpdclient-2-20-released/
こっちは要らない。

それから、 upmpdcli https://www.lesbonscomptes.com/upmpdcli/
https://www.lesbonscomptes.com/upmpdcli/pages/downloads.html
https://www.lesbonscomptes.com/upmpdcli/pages/upmpdcli-manual.html#UPMPDCLI-BUILDING
こちらも最新はmeson。
autotoolsでインストール出来るのは前のバージョンだ。

piCore、Tiny Coreでは、インストールしたソフトウェアをtczファイルという形式に固めて格納する。mesonでインストールすると、それがやりにくいのだ。
2019年にはそうだった。
今はどうなっているだろう。
最新でやってみるか、mesonでやろう。ということで、やってみるということだ。

まず、普段使用のPCにlibmpdclient-2.22をダウンロード。
https://www.musicpd.org/download/libmpdclient/2/libmpdclient-2.22.tar.xz
展開し、README.rstを確認。必要な環境を確認。

You need:
- a C99 compliant compiler (e.g. gcc)
- `Meson 0.56 `__ and `Ninja `__
Run ``meson``:
meson setup output
Compile and install::
ninja -C output
ninja -C output install

次にmpd。
https://www.musicpd.org/download/mpd/0.23/mpd-0.23.15.tar.xz
README.mdを確認。
For basic installation instructions
[read the manual](https://www.musicpd.org/doc/user/install.html).
ネット上の説明を読めということらしいので、読む。

In any case, you need:
a C++17 compiler (e.g. GCC 8 or clang 7)
Meson 0.56.0 and Ninja
Boost 1.58
pkg-config

次、upmpdcli。
https://www.lesbonscomptes.com/upmpdcli/pages/upmpdcli-manual.html#UPMPDCLI-BUILDING

For building from source, you will need a C++ compiler with C++17 support, and the development packages for the supporting libraries: libcurl, libmicrohttpd, libmpdclient, and possibly expat, depending on configuration options.
Also the Python modules for streaming service support use the python3-requests package, so you may need to install it (it is only needed at run time).
Older releases of the packages used the GNU autotools for building. Newer releases (and current git code) use meson and ninja. The change releases were libnpupnp 6.1.2, libupnpp 0.26.3 and upmpdcli 1.8.10.

（グーグル翻訳）
ソースからビルドするには、C++17 をサポートする C++ コンパイラーと、構成オプションに応じてサポート ライブラリ (libcurl、libmicrohttpd、libmpdclient、および場合によっては expat) の開発パッケージが必要です。 また、ストリーミング サービス サポート用の Python モジュールは python3-requests パッケージを使用するため、インストールする必要がある場合があります (実行時のみ必要です)。 パッケージの古いリリースでは、ビルドに GNU オートツールを使用していました。新しいリリース (および現在の git コード) では、meson と ninja が使用されます。変更リリースは、libnpupnp 6.1.2、libupnpp 0.26.3、および upmpdcli 1.8.10 でした。

必要な環境がある程度分かったところで、下記からpiCoreのイメージをダウンロード。Ras Pi b+なので、armv6。
http://tinycorelinux.net/14.x/armv6/releases/RPi/
http://tinycorelinux.net/14.x/armv6/releases/RPi/piCore-14.1.0.zip

リポジトリは下記。
http://tinycorelinux.net/14.x/armv6/tcz/

imgファイルをmicroSDに焼いて、cmdline.txt にhost=pC141bpと追記、config.txtを編集しイヤホンジャックを止めて、ラズパイに刺して電源を入れる。無事、起動した。
sshでログインし、filetool.sh -bでsshの鍵を保存する。
パーティションを拡張。2Gも足しとけばよかろう。

libmpdcliantの要求で、gcc、etcをインストール。
ついでに、どうせ要るであろうsquashfs-toolsもインストール。
tce-load -wi gcc.tcz gcc_libs.tcz gcc_libs-dev.tcz gcc_base-dev.tcz meson.tcz ninja.tcz squashfs-tools.tcz

mpdの要求で以下、インストールだ。
tce-load -wi boost-dev.tcz boost.tcz pkg-config.tcz

upmpdcli,以下、インストール。
tce-load -wi curl.tcz curl-dev.tcz libmicrohttpd.tcz libmicrohttpd-dev.tcz expat2.tcz expat2.tcz expat2-dev.tcz

加えて、PPAPで動かすつもりならnmapをインストールする必要がある。
あと、alsa関連も一応。
tce-load -wi nmap.tcz
tce-load -wi alsa-modules-6.1.68-piCore.tcz alsa.tcz alsa-utils.tcz alsa-utils-doc.tcz alsa-utils-locale.tcz alsa-plugins.tcz alsa-plugins-dev.tcz

以上で、準備完了、かな。

インストールは、libmpdclient、upmpdcli、mpd の順序で行う。

libmpdclient

エラーを吐いて止まってしまった。何が足りないんだ。
ldってなに。
https://stackoverflow.com/questions/35970824/gcc-collect2-fatal-error-cannot-find-ld
これを参考にする。
tc@pC141bp:~/libmpdclient-2.22$ export PATH=$PATH:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin
これは効果なし。
gcc入ってるから要らないと思ったけど、clang入れてみるか。

tce-load -wi clang.tcz

これで、意外にたくさんのtczファイルが追加インストールされる。
出来るかな。

libmpdclient、インストール終了。手間がかかる。2019年のときとやり方は変わらん。
まあいい、次はupmpdcliだ。

upmpdcli

え、、、え？！、Deezer Plugin、ってなに！
2021年、upmpdcli 1.5.9からDeezerに対応したようだ。
Qobuz、Tidalはもう少し古くて、Upmpdcli 1.2.0からのようだ。2017年より以前のことだ。Spotifyのプラグインはない。
python3-requests パッケージが要るって、これのことか。
どうやって使うのだろう。
https://www.lesbonscomptes.com/upmpdcli/pages/upmpdcli-manual.html#UPMPDCLI-MS-STR
上記の記載によると、昨年秋にDeezerは使えなくなったとのこと。なんとまあ。

まあいい、とりあえず、以下、順次インストールする。

libnpupnp-6.1.2.tar.gz
libupnpp-0.26.4.tar.gz
upmpdcli-1.8.11.tar.gz

これでも無理。エラー、ついには環境依存との表示が出る。

実際、「jsoncpp」はTiny Coreだとリポジトリにtczがあるけど、piCoreには用意されていない。
今、メインシステムで使っているmpdサーバー（Tiny Core OS）にupmpdcliをインストールした時にも、jsoncppが足りなくて、後からインストールしたのだ。
http://blown-lei.net/endive/blosxom.cgi/audio_diary/20210321a.htm
upmpdcliのサイトにはjsoncppについて書いてないように思うが、皆、どうしてるんだろう。

そういうわけで、Ras Pi b+にupmpdcliをインストールする試みは行き詰まった。
jsoncppをソースからインストールとなってくるといよいよハードルが高く、根負けした。

以上で、撤退である。

inter mission

upmpdcliをインストールするには「jsoncpp」というライブラリが必要になる。
aarch64のリポジトリにはtczファイルが用意されているが、armv6、armv7、armv7lには用意されていない。つまり、Ras Pi 3B以下の機種へのインストールは、容易には出来ないということだ。

そういうわけで、とりあえず、b+をPPAP Back Endにしてみた。
しかし、ノイズが入ったり音が切れたりで、快適には使えない。B+ってこうだったっけ。昔はB2で運用してたんだっけか。
http://blown-lei.net/endive/blosxom.cgi/audio_diary/20180301a.htm
昔のエントリーによると、period-sizeとbuffer-sizeを上げたらB+でもBack Endで使えるようだ。

やっぱり、3b+を使わないといけないかな、と思ったら、3b+のpiCore、aarch64のリポジトリにはnmap.tczがない。3b+以上の機種をPPAPで使うとしたら、ソースからインストールする必要がある。
いろいろ制約が多い。
そういれば、そういうこともあって、apu2に移行したような記憶が、、、どうだったかな。

さて、ということは、Roon BridgeとPPAP Back Endを一体にできるのは、うちにあるRas Piだと2bしかない、ということになる。
B+はRoon Bridgをインストールできない。
3b+はUPnP化、Roon Bridge化は出来たとしても、nmapをインストールできない。つまりmpdサーバーの3b+からUSBでDACに出力することになる。それで運用というのもありだけど、作るのが大変な割に、音質は期待できない気がする。

実は今回、Roon (RAAT)とPPAPの音質を比較したいというのが、当初の目的だった。そのためには、Roon Bridgeとncat、両方を動かせる機械を作りたい。同一の機械じゃないと比較ができない。
本当は、Roon ROCKとRoon Ready対応の製品じゃないと、Roonの真価は分からないのかもしれないが、まあ、やってみたいということだ。

Raspberry Pi 2b

そういうわけで、、、Ras Pi 2bに手を入れていく。

Roon Bridge化、成功。タブレット端末のRoonアプリ上で、Roon Bridgeとして認識されている。音も出た。

続いて、PPAP Back-End化。

音は出るだろうか。、、、なんでか、動かない。mpdからの送信を受け付けないようで、ncmpcppで「paused」と表示される。
tc@pC141b2:~$ tce-load -wi openssl-dev.tcz alsa-plugins-dev.tcz
無効。
Roon Bridgeも動かない。
ということは、同一機械での併用は出来ないのか。
PPAPのコマンドを止めたら、Roon Bridgeは動くようになった。alsa出力を奪い合うんだろうか。
その割には、Roonを止めてもPPAPは動かない。
何しろ、うまくいかない。

しかたない。
Raspberry Pi 2bでRoon BridgeとPPAP併用は止めることにする。

Raspberry Pi 3b+

さて、3b+に、mpdとupmpdcliをインストールして、PCトランスポートとして動かしてみることにした。音質への配慮は2の次だ。UPnPPPAPは使わない。基本、アップサンプリングもしない（高度な処理はRas Piには負担が大きいからだ）。

まず、piCoreをダウンロード。3B+を使うことにするので、下記から落とす。バージョンは14.1。
http://tinycorelinux.net/14.x/aarch64/
http://tinycorelinux.net/14.x/aarch64/releases/RPi/piCore64-14.1.0.zip
imgファイルをmicroSDに焼いて、cmdline.txt にhost=pC141b3pと追記、config.txtを編集しイヤホンジャックを止めて、ラズパイに刺して起動。さすがに長いので、環境構築のコマンドは羅列で済ます。

sudo fdisk -u /dev/mmcblk0
filetool.sh -b
sudo resize2fs /dev/mmcblk0p2
tce-load -wi gcc.tcz gcc_libs.tcz gcc_libs-dev.tcz gcc_base-dev.tcz meson.tcz ninja.tcz squashfs-tools.tcz
tce-load -wi boost-dev.tcz boost.tcz pkg-config.tcz clang.tcz curl.tcz curl-dev.tcz libmicrohttpd.tcz expat2.tcz expat2.tcz expat2-dev.tcz
tce-load -wi alsa.tcz alsa-utils.tcz alsa-utils-locale.tcz alsa-plugins.tcz alsa-plugins-dev.tcz
tce-load -wi jsoncpp.tcz jsoncpp-dev.tcz

ここで問題が発覚。upmpdcliのインストールに必要な、libmicrohttpd がリポジトリにない。
ソースからインストールしないといけない。無しではいけないかな。
面倒だなあ、、、止めよう。

Raspberry Pi 2b again

2bを、2台にしよう。

Roon Bridgeは既に作ってある。
だから、ここではPPAP Back-Endを作る。

http://tinycorelinux.net/14.x/armv7/releases/RPi/piCore-14.1.0.zip
zipをダウンロードし解凍。
imgファイルをmicroSDに焼いて、cmdline.txt にhost=pC141b2-ppapBEと追記、config.txtを編集しイヤホンジャックを止めて、ラズパイに刺して電源を入れる。

うっかりしてopenssl-1.1.1.tczを入れ忘れて、後からインストール。そうしたらちゃんと機能した。

結末

そんなわけで、うちではRaspberry Pi 2b が2台、メインシステムに加わった。Roon BridgeとPPAP Back-Endだ。
ちょっと、あれこれ賑やか過ぎる。そのうち、なんとかしよう。

あれこれやる合間に、久しぶりにRas Pi B+ / piCore7でmpdサーバーを作った。サブシステムに使う。
http://blown-lei.net/endive/blosxom.cgi/audio_diary/20180103a.htm
上記の過去エントリーの作り方だと、うまくいかない。
リポジトリからgcc.tczとか諸々多数のライブラリをインストールすることになっているんだけど、今、現在の時点で、gcc.tczはダウンロードできない状態になっている。リポジトリ側の都合らしい。
mpdのインストール、リポジトリからするなら、gccとか余計なライブラリは要らない。
以下、自分用構築メモ備忘録、最小限。
