你好,這是我的圖層樹使用啓用systemd服務yocto

這裏test_systemd.service是必須調用test_systemd.sh,而我試圖用service_0.1.bb
實現服務文件# This recipe performs the following tasks
# 1) Install .sh file in /home/root/ and .sh script creates a random text file
# 2) Install the .service file in systemd directory
# 3) Invoke the .sh script via .service file

問題是,當我嘗試BitBake的系統方案,拋出bitbake的一個錯誤說法test_systemd.service沒有找到。 我設法將這兩個文件都安裝在RFS中,但是當我包含systemd概念時。我得到沒有這樣的文件錯誤。可能是什麼原因 ? 錯誤消息

而且這是寫systemd BB配方正確的做法,什麼是不bitbake的這個錯誤拋出寫這篇
#Pack the path
FILES_${PN} += "/home/root"
FILES_${PN} += "/lib/systemd/system"
的意義。
感謝提示了MODS。我根據你做了改變,但仍然出現錯誤。將更新問題 – user7345878
我仍然得到相同的錯誤。不知道爲什麼Bitbake無法在其存在的位置找到該文件。 – user7345878
您目前的食譜指向'$ {D} {systemd_system_unitdir}'兩次。它應該是'$ {D} $ {systemd_system_unitdir}'。否則它在這裏工作。 – jku
