windeployqt复制许多不必要的文件。

Question

我正在为一个非常简单的Hello类型的QML应用程序创建一个具有正确依赖项的可执行文件。使用此命令时，使用以下命令

windeployqt . --release --qmldir D:\Documents\QT-Projects\HelloQML

中可执行文件的文件夹中。这样做很好，而且我可以毫无问题地运行可执行文件。但是，我发现我可以删除目录中的许多文件和文件夹，而不会影响程序的运行。为了比较，这里是原始文件夹内容。

这是我删除了所有可能的东西之后的文件夹，同时仍然允许程序运行(我没有尝试删除任何子文件夹中的任何内容)。

是否有一种方式使windeployqt不复制这么多不必要的项目？

Answer 1

如果使用最新的Qt版本之一，则可以选择不复制哪些文件。

--不使用翻译和OpenGL的二进制文件，例如：

windeployqt.exe C:\sample\sample.exe --no-translations --no-opengl-sw

Usage: windeployqt [options] [files]
Qt Deploy Tool 5.12.0

The simplest way to use windeployqt is to add the bin directory of your Qt
installation (e.g. <QT_DIR\bin>) to the PATH variable and then run:
  windeployqt <path-to-app-binary>
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 <path-to-app-qml-files> <path-to-app-binary>

在将应用程序部署到另一台PC时，可能需要这些文件中的一些。例如，您删除了opengl32sw.dll。我发现这个dll并不存在于所有的PC上，并且需要成为安装的一部分。
