Hello everyone:
I am writing an app which is designed to run on both android and iOS, we
development our app's UI usingn Qt Quick technology. But the size of the Qt
library is too big, I have to build Qt by myself (from the stable branch of git
repository) to shrink size, the build command is:
DISABLED_FEATURES='
-no-feature-TEXTODFWRITER

As you can see from the commands, I disabled many features and strip the
final libraries, after all there steps the size of the libraries is:
libQt5Core 3.3MB
libQt5Gui 2.7MB
libQt5Network 394.5KB
libQt5Qml 1.8MB
libQt5Quick 1.8MB
libQtMultimedia 456KB
But the size is still bigger than I have expected, Is there any way to
shrink the library size even further? Thanks
