WSL2のUbuntuでVitisを起動する

• Ubuntu20.04 on WSL2
• vitis 2020.2
• vitis_hls 2020.2

WSL2のUbuntu20.04にインストールしたvitisが起動してくれませんでした。ちゃんとinstallLibs.shは実行しているので必要なライブラリはインストールされているはずなのですが。。

起動しようとして失敗したときのメッセージにlogを残したとあったので覗いてみました。

swtライブラリ関連でエラーが起こっているようで怪しいのはCan't load library: /home/yoshi/.swt/lib/linux/x86_64/libswt-pi4-gtk-4932r18.soあたり。swt関連のライブラリをインストールしてきたら、vitis、vitis_hls共に起動するようになりました。

$ sudo apt install libswt-gtk-4-jni
