Ubuntu 20.04でのPybombsによるGNU Radio maint-3.9のビルド

2021/08/27 5:38 PM2021/09/19 8:18 PM

先の記事では，Ubuntu20.04でPybombsによりGNU Radio 3.9.2.0をビルド・インストールした．maint-3.9系列でのビルドを指定すれば，3.9.2.0のリリース後にGitHub上でcommitされた修正を反映したGNU Radioをビルドできそうだ．先の記事に続いて usrp39 という別のユーザを作成し，そのユーザーとして続いて作業する．下記については，先の記事ですでに終わっている．

$ sudo apt-get install python3-pip
$ sudo pip3 install pybombs
$ pybombs auto-config

$ sudo apt-get install -y python3-pygccxml
$ sudo apt install pybind11-dev

続いて，以下のように進める．

$ pybombs recipes add gr-volk git+https://github.com/gnuradio/volk.git
$ pybombs recipes add gr-recipes git+https://github.com/gnuradio/gr-recipes.git
$ pybombs recipes add gr-etcetera git+https://github.com/gnuradio/gr-etcetera.git
$ mkdir gr39

gitbranch を maint-3.9 にセットする．

$ pybombs config --package gnuradio gitbranch maint-3.9

Setting keys for packages gnuradio:
gitbranch: maint-3.9

Pybombsを使ってビルドする．

$  pybombs prefix init /home/usrp39/gr39 -a myprefix -R gnuradio-default    と入力する．

3.9.2.0をビルドしたときと全く同じようにも思えるが，よく見ると Receiving objects: 100% (175392/175392) などのようにソースコードツリーに含まれる何らかの対象物の個数に相当する数値が増えているので，異なる条件でビルドされていそうだ．

$ source ~/gr39/setup_env.sh
$ gnuradio-companion

上記のようにパスを通して GNU Radio Companionを起動すると，2021年8月27日のビルドでは，GNU Radio Companion v3.9.2.0-103-gfbfbee7e が起動した．どうやらうまくいったようだ．ちなみに，~/gr39ディレクトリは約13GBの容量を占めている．以上の手順は，ドキュメント類を眺めながら見よう見まねで行っている．手順に何かが抜けていたり，余計だったりするかもしれない．お気づきの点がありましたら，ご指摘をいただければ幸いです．
