[solved] QT Creator 5.0.2 static build

koahnig

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.":http://download.qt-project.org/official_releases/qt/4.8/4.8.4/qt-everywhere-opensource-src-4.8.4.zip You cannot simply recompile statically the source delivered with another build.

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

Thank you so much. I always just found this download page
http://qt-project.org/downloads

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\Qt5.0.2...
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
o
y

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.

QT-static-prgm

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/Projects.pro
Qmake failed, return code 3

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

koahnig

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.

QT-static-prgm

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 -.-

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

koahnig

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?

QT-static-prgm

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

koahnig

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.

QT-static-prgm

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

koahnig

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

QT-static-prgm

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

koahnig

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.

QT-static-prgm

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??

koahnig

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()":http://qt-project.org/doc/qt-5.0/qtcore/qdebug.html 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.

QT-static-prgm

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.

koahnig

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).

QT-static-prgm

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.

QT-static-prgm

ok i just retest.

file>new>qtapplication
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;
w.show();

return a.exec();
}
@

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

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}

MainWindow::~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
