Qt Qml编译问题 (QtCharts 和 windeployqt)

编译命令

# windeployqt --release [你的程序.exe] --qmldir [找到对应的安装路径]
windeployqt --release nlgMotor1.exe --qmldir D:\Qt\Qt5.12.5\5.12.5\mingw73_32\qml

# 如果你在qml中使用了 QtCharts，当前windeployqt有bug，所以还需要以下操作
# 进入 D:\Qt\Qt5.12.5\5.12.5\mingw73_32\qml，手动拷贝 QtCharts 的文件夹到程序目录下
# 然后从 D:\Qt\Qt5.12.5\5.12.5\mingw73_32\bin 拷贝 Qt5Charts.dll 到你的程序目录
# qml的chart是对Q5tCharts.dll的封装，并非完全独立写的

# 没有写 windeployqt --qml [qml目录]

windeployqt编译语法

  Usage: windeployqt [options] [files]
  Qt Deploy Tool 5.12.2

  The simplest way to use windeployqt is to add the bin directory of your Qt
  installation (e.g. ) to the PATH variable and then run:
    windeployqt 
  If ICU, ANGLE, etc. are not in the bin directory, they need to be in the PATH
  variable. If your application uses Qt Quick, run:
    windeployqt --qmldir  

  Options:
    -?, -h, --help            Displays this help.
    -v, --version             Displays version information.
    --dir          Use directory instead of binary directory.
    --libdir            Copy libraries to path.
    --plugindir         Copy plugins to path.
    --debug                   Assume debug binaries.
    --release                 Assume release binaries.
    --pdb                     Deploy .pdb files (MSVC).

                               target:   absolute path of the target files
                               relative: paths of the target files, relative
                                         to the target directory
