Q&A
前提・実現したいこと
raspberrypi zero WHでlazycastを使おうとしたときのエラーです。
raspi0でlasycastを用いてAndroidスマートフォンを接続したいと考えています。
makeでエラーが起きているのですが、わかる方がおりましたらよろしくお願いします。

試したこと
起動した後、初期設定をし、英語のままで使用しました。
その後以下のように行いました。
sudo apt update wget clone https://github.com/homeworkc/lazycast sudo apt install libx11-dev linasound2-dev libavformat-dev libavcodec-dev sudo apt install network-manager network-manager-gnome openvpn openvpn-systemd-resolved network-manager-openvpn network-manager-openvpn-gnome sudo reboot cd lazycast make
githubに書いてあるwpasupplicant_2.4-1+deb9u6_armhf.debでダウングレードもしたが、その時は実行後すぐにsegmantation errorと出ます。

/usr/bin/ld: cannot find -lilclientってエラーが出てるので、手順抜かしてるだけだと思います。
