How to compile Qt as static

I am currently writing code in Qt. How to compile the code statically?

From Qt document I came to know the following step

1) Visual Studio 2008 -> commandPrompt -> QtDir -> configure -static -> nmake

But, it took 17 GB and at the end it exited before the completion stating that "the space is not enough".

Is there any simple way to compile the Qt application as a stand alone program?

For more modern versions of Qt (i.e. Qt 6.*), the size-reduction flags mentioned above will not work. See my answer here for a comprehensive list of ways to reduce compile time/size.

Hope this helps!

You have already used the only way possible: compiling the source as static.

Some things that have a very large impact on disk size (which seems to be the problem here), with corresponding configure arguments:

  1. Disable debug: -release
  2. Disable modules you don't need, especially QtWebKit: -no-webkit -no-script -no-scripttools -no-qt3support -nomake demos -nomake tools -nomake examples
  3. Disable LTCG support, which has the nasty side effect of generating huge static libraries: no-ltcg

These should help keep the build size to a minimum.
