[SOLVED] Building Qt 5.4.1 static application for Windows 7?

Johnathon

Hi all, I have created a Window 7 based application and managed to get it running under release build. However this application requires external Qt dll files such as "QtCore5.dll" and "Qt5Gui.dll" as well as a "\platforms" folder with "qminimal.dll", "qpffscreen.dll" and "qwindows.dll".

I would like to create a standalone application which does not requires any of the external dll files, such as those mentioned above. I'm currently using

QtCreator 3.4.0 based on Qt 5.4.1
Windows 7
MinGW 4.9.1 32bit (installed via Qt Creator, C:\Qt\5.4\mingw491_32\bin\qmake.exe)

I came across many forums whose solution eventually leads to the url, https://wiki.qt.io/How_to_build_a_static_Qt_version_for_Windows_with_gcc, but it is meant for 4.7.0. A lot of the directories had since changed, removed or renamed. Does anyone have any ideas on how to make it a standalone?

Many thanks,
Johnathon

Hi and welcome to devnet

Checkout this link for Qt5
In order to build Qt yourself AFAIK you should use the source from this zip or of a previous version. The source as shipped in the prebuilds should not be used for recompilation with a different configuration.

The steps for building qt 5.4.1 are the same as for qt 4.7.0.
Have a look at the links koahnig gave you. If you still do not know what to do you could have a look at my german tutorial:
https://forum.qt.io/topic/44406/tutorial-qt-5-3-1-für-statisches-linken-builden-mingw
It base on an english tutorials, but it was updated for the 5.3.1 libs. Nothing changed to 5.4.1, so you can look up the path in the german tut ;)

If you still have question feel free to ask. I'll see how to help you.

@QT-static-prgm Thank you so much for your tutorial. After some modifications on the tutorial steps, I managed to get it working.

I have installed the Qt Creator in C:\Qt\5.5 and the opensource to C:\Qt\5.5_static. When reaching the following step:

wechselt nun in das Verzeichnis C:\Qt\Qt_5.3.1\ und wählt eure Konfiguration:
configure -static -platform win32-g++ -opengl desktop -c++11 -make libs

instead of running the command in command prompt in the directory C:\Qt\5.5, i ran the command in the directory C:\Qt\5.5_static. When finished running mingw32-make in the command prompt, there were some compiler errors as below:

I did came across the following post and the author mentioned that some of these errors can be ignored.

https://forum.qt.io/topic/49387/how-to-build-qt-5-4-statically-on-window-7-compression-exe-by-upx/2

Following through to the end of the tutorial, I managed to create a and compile a new project with standalone static build kit. I copied the released version of the executable file onto Desktop and run it, it ran without any errors.

QT-static-prgm, thank you very much for your help.

I'm facing another issue right now, I can build a new project as a standalone when I choose the static kit. But when I add the following to the project .pro file:

QT += core gui \
serialport

QtCreator immediately prompts an error saying

Project ERROR: Unknown module(s) in QT: serialport

I have tried some of the suggestions like below:

Run command prompt and go to C:\Qt\5.5_static\qtserialport
Run the command: qmake qtserialport.pro

but it still doesn't work.

Has anyone work with QtSerialPort in static Qt?

Thank you

Johnathon

@Johnathon
It could be better to start another thread. Even though the topic is related.
One of the developers of serialPort is typically very responsive.

@koahnig
Thank you for your suggestion, I will do that.
