[SOLVED] NEW and CONFUSED

nHx4U

I need all the help I can get. I'm an absolute beginner with Qt and C++
I've downloaded and installed: Qt 5.0.2 with mingw 4.7.4 to desktop PC running Windows 7 x64
I can run the examples directly from Qt Creator and they are OK! However, when I go through the first tutorial ("Transitions") I get errors and the tutorial does NOT run.

Also. If I copy the "Examples" folder to another directory, the examples will not build/run from this new location.

See below.

Thanks

Thanks for your quick response.
I will re-install and try the tutorials again tonight, and inform you of my
results.

nHx4U

I re-installed Qt 5.1 with MingW48. I completed the beginners tutorial.
All worked fine. >>> However >>>>
Where's the "EXE"? I've built and run the tutorial but it doesn't create an independent application. Is there another step? or is the exe hidden in a folder somewhere? I've also copied the exe from the included example demo's, and they don't run outside the original example folder.

I appreciate your help.

Thanks.

Is there another step? or is the exe hidden in a folder somewhere?[/quote]With your project open, click the "Projects" button on the left of Qt Creator. That will show you the "build directory" where the .exe is produced.

This technique is called "shadow building" -- the .exe is built in a folder separate to your source code, to keep your code directory clean.

[quote]I've also copied the exe from the included example demo's, and they don't run outside the original example folder.[/quote]You need more than the .exe. You also need the DLLs that the .exe depends on. See "Creating the Application Package" at http://qt-project.org/doc/qt-5.1/qtdoc/deployment-windows.html#creating-the-application-package (but the only plugin you need is platforms\qwindows.dll -- ignore the instructions for other plugins)

nHx4U

Sorry. Still can't create a "Stand-Alone" package. I followed your instructions and created a "release" version (exe) in a separate folder. I've added a subfolder "platforms\windows.dll". I used "Dependency Walker" and copied the suggested .dll's into the folder, and it still won't run!. (Lots of DLL's. Some show up in 2 different locations and file sizes: one in MingW and also in Qt. I selected the mingw files. These were typically larger than the similar named Qt dlls.)

I created a simple app from:

http://qt-project.org/wiki/Basic_Qt_Programming_Tutorial

and also tried to follow the instructions in:

http://qt-project.org/doc/qt-5.0/qtdoc/deployment-windows.html#application-dependencies

JKSH

Please list all the contents of the folder where you tried to put your standalone package (.exe, .dlls, and subdirectories) -- it's hard to tell what you've put in there from broad descriptions alone.

JKSH

Sorry, I missed your last post.

"PLUGINS\Qwindows.dll" should be "platforms\qwindows.dll"

You have both Qt 4 (QtCore4.dll, QtGui4.dll) as well as Qt 5 (Qt5Core.dll, Qt5Gui.dll) DLLs -- those don't go together. Uninstall Qt 4 from your system completely and remove the Qt 4 DLLs. Then, delete these and re-compile your project

Qt-Ttutorial-01.exe
moc_widget.cpp
*.o

Get rid of api-ms-win-core-console-l1-1-0.dll and IEShims.dll -- those are system DLLS which you shouldn't need to deploy (Dependency Walker gave you false warnings here)

[quote]Some show up in 2 different locations and file sizes: one in MingW and also in Qt. I selected the mingw files. [/quote] Use the ones in the "Qt" folder. Also, please list the DLLs that you found in two places.

Some questions:

Did you uninstall Qt 5.0.2 before trying to compile with Qt 5.1? If not, uninstall Qt 5.0.2
Do you have multiple installations of MinGW in your computer? If you do, uninstall all others except for the one that came with Qt.

nHx4U

Thanks for your reply.
I've performed your last suggestions, and now get these errors:

When clicking Qt-Ttutorial-01.exe from RELEASE folder:

The procedure entry point
_Z8qWinMainP11HINSTANCE_S0_PciRiR7QVectorIS1_E could not
be located in the dynamic link library Qt5Core.dll.

When running release build from Qt Creator (Qt-Tutorial-01.pro):

Starting C:\Users\Steve\Desktop\Qt_Tutorials\Qt-Tutorial-01\build-Qt-Ttutorial-01-Desktop_Qt_5_1_0_MinGW_32bit-Release\release\Qt-Ttutorial-01.exe...
The program has unexpectedly finished.
C:\Users\Steve\Desktop\Qt_Tutorials\Qt-Tutorial-01\build-Qt-Ttutorial-01-Desktop_Qt_5_1_0_MinGW_32bit-Release\release\Qt-Ttutorial-01.exe exited with code -1073741511

3. Running from the DEBUG build (in Qt Creator) works properly.

eMixam

For your 1st and 2nd error I would say it's a .dll problem, do you still have Qt4 or Qt5.0.2 dll in your release folder ?
Maybe you're compiling with Qt5.1 but the ones that are used are Qt5.0.2.

nHx4U

Thought I deleted everything other than Qt 5.1

I will use a "deep" uninstaller and clear everything Qt and re-install Qt 5.1

I will get back to you on results in a few days.

Thanks for your help.

The procedure entry point
_Z8qWinMainP11HINSTANCE_S0_PciRiR7QVectorIS1_E could not
be located in the dynamic link library Qt5Core.dll.[/quote]That means the program is using the wrong version of the DLL.

Question: Are you absolutely sure that you only have 1 version of Qt in your computer, and you have uninstalled all other versions?

Do this first:

Delete the folder C:\Users\Steve\Desktop\Qt_Tutorials\Qt-Tutorial-01\build-Qt-Ttutorial-01-Desktop_Qt_5_1_0_MinGW_32bit-Release

Build your project again in Qt Creator

Copy the DLLs that you need from C:\Qt\Qt5.1.0\mingw48_32\bin -- (if this is NOT where your DLLs are found, tell us the full directory)

Secondly, open a Windows Command Prompt (click Start -> Run, type in "cmd", and press Enter). Run this command...
@
path > C:\Users\Steve\Desktop\path.txt
@
...then open the text file on your desktop and paste the result here.

TO: JKSH (and others who have responded). Thank you very much.
I have performed tasks 1,2,3 above AND it actually works! :-)

Below is list of files and locations. Actual DLLs used were copied from Qt..\mingw subfolder.

HERE IS THE PATH FILE:

How does one know which files to include in the release folder - Other than "Dependency Walker"? When a particular DLL shows up in both Qt and mingw do you always choose the mingw? The mingw files are typically larger than the ones in the Qt folder.

I will now go on to attempt something more complex.

Thanks for all your help. Really appreciate it.

JKSH

Glad to hear! :) I hope you have fun exploring what Qt has to offer. If you have any more questions, please feel free to ask in these forums, and I'm sure someone will try to help you.

From this exercise, the take-home messages are:

Be aware of the libraries that you're using.
** If there are multiple versions on your computer, always ensure that you are linking to the correct version, and that you copy the correct DLLs
When you upgrade or change something (such as your libraries, or even your source code), you may need to delete your previously-compiled files because they could be linked to old libraries
** Some problems can be solved by deleting those files and re-compiling from scratch, like what you just did

This folder contains your Qt library (YOU SHOULD COPY THESE DLLS FOR YOUR STANDALONE APPLICATION):

C:\Qt-51\Qt5.1.0\5.1\mingw48_32\bin\

This folder contains the Qt Creator IDE (code editor), not your Qt library

C:\Qt-51\Qt5.1.0\Tools\QtCreator\bin\

This folder contains your MinGW compiler

C:\Qt-51\Qt5.1.0\Tools\mingw48_32\bin

Qt Creator is a standalone application. Its DLLs could be older than your library, so you don't want to copy those!

Thanks for your response.
I downloaded the Qt5.1 from: http://download.qt-project.org/official_releases/qt/5.1/5.1.0/qt-windows-opensource-5.1.0-mingw48_opengl-x86-offline.exe
After I installed, I have a folder: C:\Qt\Qt5.1.0
I used all library from: C:\Qt\Qt5.1.0\5.1.0\mingw48_32\bin
I searched and found a lot solution but no ones work for me.
Note: I use Qwt-6.1.0 in my application, I build and install it by Command Prompt from Qt the I installed

JKSH

The MinGW in that package uses Dwarf-2 instead of SJLJ, so replace libgcc_s_sjlj-1.dll with libgcc_s_dw2-1.dll.

Also, MinGW has changed: you don't need mingwm10.dll anymore, but you now need libwinpthread-1.dll
