[solved] QT Creator 5.0.2 static build

  • So after no one could help me in the german forum i give it a try in the english one.

    My problem is easy and if i belive all the threads here the soluion is easy, too.

    I made a small program with QT Creator and now i want to have a stand-alone .exe I installed QT 5.0.2 with the source. i tried to build qt static and i think i did it. But the builded programms are still not staticly.

    What i want is simple. in the left down corner you can select what project should be build and if it should be release or debugg. i would like to have an other option static release.

    The main problem i have is that all the path shown in the tuts are not the same i have. Also everybody says edit the mekspec config.
    Add -static at QMAKE_LFLAGS = ... just before all the other options. but there are no other option by default.

    When doing the confoguration for building qt i cannot choose -no-exceptions. it simply doesn't exist.

    I really hope someone can explain me how to build my programs staticly.
    a i forget i use the minGW compiler. and windows 8

    Thank you

  • welcome to devnet

    In order to build a static application, you need a static build of Qt libs first. All pre-compiled Qt libs are dynamic.

    First you need to make your own static Qt libs. However, you need to be aware of the license issues when you like to distribute your application.

    Second you can compile your application as statatic and link with your set of static Qt libs.

    AFAIK it is still better to download the "Qt source from here.": You cannot simply recompile statically the source delivered with another build.

    [edit, there is also a "wiki entry": for static build Qt libs in German. A bit dusty :-( ]

  • Thank you so much. I always just found this download page

    I will have a look at this in the noon.
    And thank you for the german wiki.

  • mh i have some problem with this again.

    So i now have installed: QT Creator 5.0.2 32bit MinGW.

    The files you gave me.
    The Path are:
    C:\Qt\Qt static...

    in C:\Qt\Qt static\mkspecs\win32-g++\qmake.conf i changed the following:

    QMAKE_CFLAGS_RELEASE = -Os -momit-leaf-frame-pointer | removed the other things
    QMAKE_LFLAGS = -static -static-libgcc … | added this, there where nothing by default
    DEFINES += QT_STATIC_BUILD | removed the other things

    C:\Qt\Qt static\qmake\Makefile.win32-g++:

    LFLAGS = -static -static-libgcc … | so now it looks like -static -static-libgcc -s

    C:\Qt\Qt static\src\3rdparty\webkit\Source\WebKit.pri :

    CONFIG += staticlib added this at line 2.

    Than i startet the console from QT Creator 5.0.2 changed to C:\Qt\Qt static
    my inputs:
    configure -static -release -platform win32-g++ -no-exceptions

    The last output lines:
    mingw32-make: *** No rule to make target 'C:\Qt\Qt', needed by 'project.o'. Stop.
    del many o-files
    C:\Qt\Qt static\qmake\project.o konnte nicht gefunden werden
    mingw32-make: *** No rule to make target 'C:\Qt\Qt' needed by 'project.o'. Stop
    Building qmake failed, return code 2

    I hope you can help me

  • hmmm ??

    I have not build Qt 5.0 myself in any version yet. Unfortunately, the static build I did was under Linux with Qt 4.6.x version. That was really very easy besides the waiting time. No changes of conf files required IIRC.

    You need to make sure that another version is available through the path settings I guess. However, that should be already the case anyway, otherwise you have not compiled apparently already a lot of stuff.

    Oh, I think i t could be the forward/backward slash problem. If you have typed in the files somewhere a path, you have to use '/' the backward version is often used for continuation lines. The forward slash is standard in Linux but Windows understands it too. Everything with folder separation in Qt should be done with forward slash '/'. Saves a lot of trouble.

    Furthermore, if you have decided the folder name "C:\Qt\Qt static", use something with a space e.g. "C:/Qt/Qt_static" should be fine.

  • ok the / \ thing i managed it was the qt space static now it made a lot more things, but no i get error return 3 :D

    What is the maximum error code?? XD

    But seams to be something simple
    Generating Makefiles...
    Failure to read QMAKESPEC conf file c:\QT\QT5.0.2\Src\qtbase\mkspecs\win32-g++\qmake.conf.
    Error processing project file: C:/QT/QT_static/
    Qmake failed, return code 3

    So why is the qmake process doing something in the Qt5.0.2 folder?? it shouldn't

  • Do not start the command prompt through creator. That might be the problem. Start the cmd.exe under "Start" or whatever it is in your version. Creator will add its own environment, which you do not want.

  • WUHU the first step runs without problems :D

    I added the QDIR in the enviroment Variables in the past and that showed to the wrong path :D changed, restart and than it worked :D

    but not the mingw32-make -.-

    @C:\Qt\Qt_static>mingw32-make sub-src
    cd src\tools\bootstrap\ && mingw32-make -f Makefile

    hope this says something to you. Google sayed there is something wrong with the unicode (?) but not how to fix

  • Did you do a confclean before new configure?
    Could be a problem with some leftover from previous configuration.
    Do you have special settings with respect to unicode?

  • i did not a clean, because i made the steps from the wiki to clean up and it seams to me to be clean.

    settings are:
    -static -platfrom win32-g++ -release -no-exceptions

  • Do not know if this is enough.

    At the end of configure it says something like
    To reconfigure, run 'make confclean' and 'configure'

    This text I have copied from the linux configure file, but the windows version displays something similar.

    In your case probably
    To reconfigure, run 'mingw32-make confclean' and 'configure'

    A mixture of settings from your previous trials is my only explanation at the moment. So a confclean would be helpful.

    I doubt that this is general problem, because it would be a bug.

  • still the same problem. At an other PC it worked. to build QT staticly, but it couldn't build the project

  • You are aware of differences between PCs?
    Those differences might be the reason for your problem. :-(

  • Jep i found it. fopr me i did all the steps i should do befor starting building. for the other i didn't. ANd i now know what the problem was. in makfile.conf the Define line says something about unicode. the last time i deletet all and replaced with the thing from the tut. this time i added the part from the tut and sice 1 hour it's building :D

  • Good to know.

    Typically it takes a bit of time.

    Is there a problem with the German wiki entry?
    If so, you should correct it. If you have doubt that it is general mark it as a difference for building Qt 5.

    If you want I can proof read.

  • Hi,

    yes i think i'll make a report of what i made to get it running.

    but before i need you help again.

    I have no problem with building. The exe is 164.431KB big.

    looks good i think. But when open it nothing happens. and if i run it with QT i get the messege
    Programm abgestürzt ..... Rückgabewert -1073741819
    something know about this??

  • Well, what can I say besides that your app crashed :-(

    You need to use the debugger and step through to the point where the app is crashing. Alternatively, you have to do it like our ancestors ( nach alter Väters Sitte ) put in some output statements where you think the application steps through.

    With MinGW you can use gdb for debugging. When debugging you can look at the values, if there is something wrong and stuff. If you haven't done before, it is good thing to look at, if you have done before, sorry for telling the obvious stuff.

    Sometimes it is good to make a mixed approach debugging and output statements. BTW for output during your debug session "qDebug()": is very helpful. You can do a lot of neat stuff with it.

    You can use more or less as cerr and cout in standard c++.

    By summarizing your findings you can update the wiki entry. Typically you have only a few things to add. So, it could be less work than writing a complete entry.

  • thanks for the link to the debug Class. That's really new for me.

    Normaly i debugg with couts :D

    the problem is, that this programm i wanted to be static has no errors.

    because it's a complete clean new QT applicattion.
    just made
    file>new>qt c++ application>next>next......
    added CONFIG += static in the .pro file, build. and that's it. the building toke a very long time, but there where no errors.

  • BTW it is Qt. QT stands for QuickTime.

    Oh, you got a "hello world" test application only. Or is it more?
    You are writing of a long compile time. What do you mean with long?

    I would assume that the problem is with the compile settings. A mixture of the "kit/tool chain". I doubt that just adding "static" to the .pro will do the job.

    To use qdebug I can really recommend. I used Qt already for a couple of years until I have started with qDebug. It looked cumbersome and why should you use when cout and cerr is available. However, together with Qt creator it makes sense and also you can more easily redirect the output stuff (e.g. to a file or a socket).

  • it's even less than a hello world. its an empty window that should apear.

    with long time i mean it seams to me to be minuts, but i think in real it was a bout 30 sec. for complex programms i made without static let'a take an Image Filter prgm it was just a few sec.

    i'll have a look at my test prgm in the afternoon. i have no pc here at the moment.

  • ok i just retest.

    Kits:Desktop and desktop static
    Desktop, without static, works fine.
    Desktop with static, builds fine, but crashes.

    @#include "mainwindow.h"
    #include <QApplication>

    int main(int argc, char *argv[])
    QApplication a(argc, argv);
    MainWindow w;;

    return a.exec();

    @#include "mainwindow.h"
    #include "ui_mainwindow.h"

    MainWindow::MainWindow(QWidget *parent) :
    ui(new Ui::MainWindow)

    delete ui;

    you see it's a normal clean new Application.
    Also in the pro file i changed nothing.

    When debugging i get the error

    bq. Der Prozess wurde nach Erhalt eines Signals vom Betriebssystem angehalten
    Name des Signals: SIGSEGV
    Bedeutung: Segmentation fault

    Free translated:

    bq. The Prozess was stopped after receive a signal from operatingsystem
    Name of the signal: SIGSEGV
    Meaning: Segmentation fault

    So a friend got this a while ago, when using a pointer showing on a memory that was not from the Application. But this works without static and is a clean new App.
    I really hope someone can help me

    The debugger stopps showing me a file named qatomic_i386.h
    never heard something about this.
    I toke the time it takes to build:
    static debugg: 20 sec
    static release : < 10sec
    normal debugg: < 5sec
    normal release: < 5sec

  • I assume you are using Qt creator for creating your app.

    What do you change when switching from dynamic to static build?

    The differences there are essential. My guess is that the compilation of the static app doesn't use a consistent memory model.

    In creator go to "Options"->"Build&Run" under the Tabs "Kits" and "Qt versions" you find what you have installed and accessible.
    On the left side of creator under "Projects" ->"Build&Run" you can find the actual kits used for your build. With manage kits, you have a link to the options menu.
    In the "Projects" menu you can switch between different setups.

    When switching setups, I found it helpful to rerun qmake from creator. This makes sure that you use the settings you see. For your small project it does not matter anyhow and it saves a lot of headaches. Use also shadow build.

    Probably you should post "part" of your error messages as displayed.

    PS: I am to lazy to translate the menu entries back to German. I prefer the English terms and have switched the language of creator a long time ago. ;-)

  • Yes. I have the Creator 5.0.2. There i made a new Project.
    Name: test
    Desktop Qt 5.0.2 MinGW 32bit
    Desktop Qt4.8.4 (Qt_static)

    Options>..>Qt Versions give me a ! at the Qt 4.8.4 (Qt_static) version.
    The details say Hilfskomponeten: keine verfügbar
    and Es ist kein qmlviewer installiert

    Options...>Kits There is also a ! at the static Kit.
    The Message is Warnung: Der Compiler ... erstellt möglicherweise keinen mit der Qt Version ... kompatiblen Code.

    So maybe it's because i use Qt 5.0.2 Creator and Qt 4.8.4 for static??

  • YEAH!!!!!
    It works thank you a lot.

    The Problem was i cloned the Kit. And so it toke the minGW from Qt. I now deleted it and made a new one and choosed the MinGW in my C:\MinGW direction. I installed a while ago for Eclipse.

    And now it works :D

    I have just a small problem. I one Programm i made i use try and catch. and for some reason the compiler give me the error
    exception handling disabled, use -fexceptions to enable
    What does it mean? Can't i use try catch for static release?? for dynamic it works.
    Or do i only need a option for compiling??

  • Congratulations!! :D

    Just for clarification. There is no Qt creator version 5... out yet, ;-)
    What you have installed are the Qt libs version 5.0.2 together with Qt creator version 2.7 something.
    Qt creator is an IDE using also Qt libs. However, it may be used with different Qt lib versions.

    With the exceptions I am not sure right away.
    You need to check MinGW docs if the switch has to be used throughout all libs. IIRC this is not a requirement, but you should better check.

    If it is an requirement than you need to recompile Qt libs. This implies that Qt libs can be compiled with exceptions switched on.

    I cannot imagine that there should be a problem, because it would be too common.
    You would need to set the compile switch in your .pro. Checkout the" qmake documentation": for more details. Checkout the QMAKE_CFLAGS_... and QMAKE_CXXFLAGS...

  • Ok.

    just saw there is an other problem. When there is a unused variable. it doesn't work eighter.

    The only problem, when using clickable lables the compiler say unsused, but it's is used.

    can it be that the option -no-exceptions is the problem??


    ok forget it. it works :D

    but how can i make the compiler using öäü...??
    with the dynamic it wörks, now i get a A with an ~ over it for a Ö.

  • The Umlaute is more a character set problem, I believe.

    Qt has "QLocale": for this. However, that stuff is completely outside of my experience.

  • With QLocale it works.

    i made a thread here
    how i get Qt static working.

    Just noticed, that Qt now didn't find the
    #include <Q...>
    for dynamic :D but i don't care i like static more.

  • Using static Qt libs or static libs in general has certainly advantages.
    However as noted already right at the beginning:
    [quote author="koahnig" date="1372231046"]
    First you need to make your own static Qt libs. However, you need to be aware of the license issues when you like to distribute your application.

    "Here is the link to the license options":

  • Jep i know. And at the moment i'm not thinking of doing a non opensource prgm. But the problem was only with one programm. don't know why. an other programm with QApplication header works.
