1.安装Qt的基本库与IDE

sudo apt-get install qt5-default
sudo apt-get install qtcreator

2.安装qmake Cmake

sudo apt-get install qt5-qmake

sudo apt install cmake

3.安装g++，gcc

sudo apt install g++ gcc

4.安装QtQucik库用来开发qml页面

sudo apt-get install qtdeclarative5-dev

5.安装QMLmodule

sudo apt install qml-module-qtquick-controls2

6.安装QtMultimedia库

sudo apt-get install qtmultimedia5-dev
sudo apt-get install libqt5multimedia5-plugins

sudo apt install qml-module-qtmultimedia

7.其他开发库

sudo apt install qml-module-qtquick-extras

sudo apt install qml-module-qt-labs-platform

8.编译安装mqtt

cd /home/linaro/kaifa

git init

git clone git://code.qt.io/qt/qtmqtt.git

git branch -a

cd qtmqtt/

git checkout origin/5.15.2

qmake

make -j8

等待编译完成后安装

make install

9.编译QtLocation 解决Unknown module(s) in QT: location-private positioning-private

cd /home/linaro/kaifa

git init

git clone git://code.qt.io/qt/qtlocation.git

git branch -a

cd qtlocation/

git checkout origin/5.15

mkdir build

cd build

sudo apt install qtbase5-private-dev qtdeclarative5-private-dev

qmake ../qtlocation.pro

make -j8

等待编译完成后安装

make install

10.位置定位相关

sudo apt install qtbase5-private-dev

sudo apt install qtlocation5-dev qtpositioning5-dev

安装qt例子 apt-get install qtbase5-examples

总结

1.在qt的pro文件缺少Qt+=的模块时需要源码编译或使用命令直接安装

直接安装：

Unknown module(s) in QT: webchannel webengine
sudo apt install qtwebengine5-dev

Unknown module(s) in QT: webview
sudo apt install libqt5webview5-dev

下载源码编译：安装mqtt

2.在qml中import导入的包可以直接使用命令下载

QML module not found(QtQuick.Controls)

apt-get install qml qmlscene

apt-get install qtdeclarative5-dev

apt -y install qml-module-qtquick-controls

apt -y install qml-module-qtquick-controls2

QML module not found(QtQuick.Dialogs)

apt install qml-module-qtquick-dialogs

module "QtQuick.Shapes" is not installed

apt install qml-module-qtquick-shapes

"Qt.labs.folderlistmodel" is not installed

apt install qml-module-qt-labs-folderlistmodel

"Qt.labs.settings" is not installed

apt install qml-module-qt-labs-settings

“QtWebChannel” is not installed

sudo apt install qml-module-qtwebengine

sudo apt install qml-module-qtwebview

sudo apt install qml-module-qtwebchannel

如果在运行某些程序报错原因是缺少某些库
可用sudo apt install lib* 或者qml*来模糊匹配可能需要的库（根据遇到的错误报告来安装）
