Building dependency free standalone QT 4 applications

**ia32** · 29th January 2007, 18:27

How can I build QT 4 applications that doesn't depend on mingwm10.dll and QT4 dll files? I've seen QT3 programs (like SQLite Database Browser) which work as standalone exe without requiring mingwm10.dll or QT library DLLs.

I just built a static exe for a simple application (which has only a a "quit" pushbutton). The filesize is unbelievable, 52.1 MB!!! Is it normal for static QT4 executables?

And how do I revert to default settings? Is just undoing the changes to qmake.conf and running ('configure' without any paramenter + mingw32-make sub-src) enough?

Sounds like you have built a debug version. Try rebuilding after "qmake -config release".

After "qmake -config release" it's much smaller, but still 7.2 MB

Is there any way to make static exes of a saner size?

BTW, thanks to everyone for help.

Try stripping the executable or use UPX.

Which executable stripper should I use? Something like StripReloc?

It really doesn't matter, as long as it works well. The one you have found works a bit differently, so you can try it together with, for example, strip.exe that comes with MinGW's binutils package.
