OMNeT++6.0をWebAssemblyで動かす

zigen 2022/07/28

前にやってたやつでは、forkして普通にcommitしてたけど、OMNeT++のバージョンが上がって、大量の変更が入って動かなくなってしまったので、もう一度作り直してく

zigen 2022/07/28

zigen/omnetpp-wasm をcloneしてきて、omnetppをomnetpp-6.0.x branchにcheckoutした。

docker_build.shでimageをbuildして、docker_run.shでコンテナに入る。
まずQtのビルドをする。build_all.shを眺めつつビルドしてみる。

cd ~/qtbase
./configure -xplatform wasm-emscripten -prefix $PWD/qtbase -opensource -no-compile-examples -confirm-license
make -j4
make install

よさそう。

zigen 2022/07/28

次にomnetpp自体のビルドをしていく。前回同様emscripten任せでやってく。
omnetppディレクトリの中で
emconfigure ./configure するとem++がうまく認識されずにエラーを吐く。とりあえずconfigureいじって通そう

あとはまぁbuild_all.shを眺めつつOMNeT++のビルドをしていく。
simのビルドでこけてしまった

このエラー、docker imageに突っ込んでおいたopp_msgtoolsのバージョンが古いのが原因か。更新しよう

zigen 2022/07/29

直した。

とりあえずビルドはできて、samplesのtictocもビルドできるようになった。
しかし、htmlなどが生成されないので、前回と同じようにMakefile.inc.inをいじって、make時に生成していく。

zigen 2022/07/29

Makefile.inc.inのpatchをつくる。とりあえず前回のから引っ張ってくるとこんな感じ

/emsdk/upstream/emscripten/emar cr qcs

emarにcrとqcsが渡ってるのがおかしい。qcsだけでいいはずだ。
というわけで、crを取り除いてemarを叩いたらビルドが通った。

次は、これがどこで埋め込まれたかを探して、直していく

sampleをmakeしてみたらduplicate symbolでこけた。シンボルがどのタイミングで突っ込まれたのかを知る必要がある

arのオプションを直した。5の時と変わってるのか？

とりあえずomnetpp/samples/tictocで emmake make index.html するとjs, html, data, wasmが一通り生成される。
omnetpp/samples/tictoc/emcc-releaseでpython3 -m http.server してlocalhost:8000にアクセスすると、wasmが動く。

が、エラーを吐いて死ぬ。

というわけで実行してみると、main loopまわりでこける。これは直すの簡単で、Qtに新たなイベントループを作らせないように書き換えていくだけ。大変なんだけど。

結構昔とメソッド名とか変わってて苦戦している。そしてスタックトレースが役に立たないので、ひたすらprintデバッグするしかない

とりあえず画面が表示されるところまで持ってきた

イベントループを避けるようなpatchを当てたので、アニメーションが動くところまできた。
しかし、どうにもicons.qrcで示されたsvgファイルがうまく読み込まれていない。
なので、このような殺風景な画面になっている。

OMNeT++6になった時点で元々png形式だったアイコンがsvgになったのが原因かもしれない。
pngに変換してicons.qrcでそのpngファイルを指定すると表示された。

SVGについてはQtSVGが必要らしいので、ビルドして使ってみるか

QtSvgをいれて、LDFlagsに追加して、Pluginをimportしたら動いた
