How to build a static Qt version for Windows with GCC

This guide contains the way, I took and which worked for me. I hope it can help you a little bit.

Preparation

First download the QtSDK you need, I took 4.7.0 and install it (incl. gcc).

Then copy the complete qt file tree from Path-To-Qt-SDK\qt to Path-To-Qt-SDK\qt-static (or whatever path you prefer).

copy Path-To-Qt-SDK\bin\qtenv.bat to static folder and adapt content
—> replace xxx\qt with XXX\qt_static

Cleaning up the folders

As you copied the sources from an existing build, you have to clean it up, before doing a new build. To get this, do the following:

Editing the config files for static build

Now you have to edit some configuration files, to enable static builds and also to like statically against the mingw c library:

build

  1. Open a command shell and go to the following path: Path-To-Qt-SDK\qt_static
  2. call configure with the needed options. The one I took are:
    • configure.exe -static -debug-and-release -opensource -confirm-license -platform win32-g++ -no-exceptions -dont-process -no-qt3support -webkit -qt-sql-sqlite -qt-zlib -qt-libpng -qt-libjpeg
    • the important ones are: * -static -platform win32-g++ -no-exceptions*
    • Now you have to build the makefiles (but only for the libraries, not for the tools):
    • bin\qmake.exe projects.pro QT_BUILD_PARTS=“libs” JAVASCRIPTCORE_JIT=“yes”
    • Now you can build Qt:
    • mingw32-make.exe
    • go and have some coffee. On my machine, it took about 3 hours (Laptop with Intel Core2 Duo T7700 2,4 GHz, 2 GB RAM, Windows 7 Professional, 32 Bit)

Other stuff

I do not recomend to build the tools (designer, assitant, etc.) as you have them in QtCreator so you don’t need them anymore. If you really want to execute them (like lrelease, lupdate), take the ones from the dynamic libraries folder (Path-To-Qt-SDK\qt\bin, incl. the needed dlls) :-)

Optimization

As the binaries might get really big, and you perhaps want to distribute them via the net, you should make them smaller. To achieve that, you can use tools like upx [upx.sourceforge.net] (http://upx.sourceforge.net)

How to integrate static version of Qt additionally to QtCreator

Open QtCreator and go to the Tools / Options menu. Select Qt4:
Select Options - Qt4 - Add
Add a new version by pressing the plus button
enter a name and the path to qmake (Path-To-Qt-SDK\qt_static\bin\qmake.exe)
add the MinGW directory (copy from 4.7.0)
Changes in the settings

If you create a new project, you are asked, which Qt version you want to use. Leave both checkboxes checked.

Create new project

If you already have a project and want to add this version, go to Projects (left hand of QtCreator) and add a setting.

Change project settings

For the static project configuration, you should add CONFIG+=static in the command line.

Open the project settings, and press details for the qmake step. In the additional arguments, add CONFIG+=static

changes qmake step

In the project (*.pro) file, add the following:

  1. static { # everything below takes effect with CONFIG += static
  2. CONFIG += static
  3. CONFIG += staticlib # this is needed if you create a static library, not a static executable
  4. DEFINES += STATIC
  5. message("~~~ static build ~~~") # this is for information, that the static build is done
  6. mac: TARGET = $join(TARGET,,,_static) #this adds an _static in the end, so you can seperate static build from non static build
  7. win32: TARGET = $join(TARGET,,,s) #this adds an s in the end, so you can seperate static build from non static build
  8. }

What also makes sense is to add a d to the binary, if you create a debug build:

  1. # change the nama of the binary, if it is build in debug mode
  2. CONFIG(debug, debug|release) {
  3. mac: TARGET = $join(TARGET,,,_debug)
  4. win32: TARGET = $join(TARGET,,,d)
  5. }

Now you have it. Build the static version (select he static project settings and build it).
