Androidスマートフォンに接続するために、Arch LinuxコンピュータでWiFi Directを実行しようとしています。ただし、WiFi Directピアを見つけようとすると、FAIL他のエラーメッセージなしでこのメッセージが返されます。問題をどのように知ることができますか？

フォローするwpa_supplicantのP2P READMEそして このブログ投稿、gitでwpa_supplicantをコンパイルしました（git://w1.fi/srv/git/hostap.git2017年5月31日現在、repo、commit、master、およびビルド設定については以下を参照）。2d18ab40826ecaec26bfd82d42dcb08f2715e362

起動しwpa_supplicantてwpa_cliコマンドを実行した後p2p_find、出力またはsyslog FAIL（）に他の情報がないメッセージが返されました。wpa_cliwpa_supplicantjournalctl -f

wpa_supplicant便利なエラーメッセージを表示するにはどうすればよいですか？
