I'll leave it for others to pass comment on the standard configure options and size, but if you're really desperate for every last saving then removing the locales you don't need can save you 230 KB (on Linux 64bit it reduces my default release build from 5.5MB to 5.2MB), but it's a manual process: 1) Download http://unicode.org/Public/cldr/24/core.zip and unzip 2) Run "../path/to/qt5/qtbase/util/local_database/cldr2qlocalexml.py core/common/main >> qlocale.xml" 3) Edit qlocale.xml to remove all the locales you don't need: only remove <locale> groups from inside <localeList> and nothing else, I suggest you always keep C and en_US in addition to the locales you require. 4) Run "../path/to/qt5/qtbase/util/local_database/qlocalexml2cpp.py qlocale.xml ../path/to/qt5/qtbase/" I could probably modify the locale_database scripts to make it easier to choose a list of required locales, but I'm hoping to work on the QLocale rewrite for 5.4 to remove the data entirely.
