構建 qtconnectivity bluez 缺失

Question

我正在嘗試從源代碼版本 5.12.3 為我的主機系統（Ubuntu 18.04 VM）構建 qtconnectivity。 當我嘗試在項目文件上運行 qmake 時，出現此錯誤：

Project ERROR: Could not find feature bluez.

我安裝了所有該死的 bluez package，但是 bluetoothd 守護程序沒有運行，我想這是問題所在。 這是我已安裝的藍牙相關軟件包的列表：

udo apt list --installed | grep 'bluez\|bluetooth'

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

有誰知道如何解決這個錯誤？

Answer 1

通常，您需要安裝-dev package 才能在編譯中使用庫。

這是 qtconnectivity 使用的測試： https://github.com/qt/qtconnectivity/blob/dev/config.tests/bluez/main.cpp 。 您需要一個包含bluetooth/bluetooth.h的 package 。

在 package 內容中按文件名搜索顯示libbluetooth-dev 。
