Problems running projects

ZapB

This is the same type of error. The system cannot find another dll. In this case MSVCP71D.dll. This looks to be a debug dll from the MS Visual C toolchain.

Can you clarify which compiler you are using to build your app please? You should be using mingw or MSVC not both. What is your Qt built against? From your previous posts it looks like you are using Mingw. I am not sure why you have this dependency on the MSVC debug runtime.

Please use dependency walker. With this you will see which lib is missing.

Thanks for still providing help.

I think I am using mingw but how can I know for sure?

Do you think Microsoft Visual Studio 2010 has something to do with this? At work I have NetBeans, Qt, Microsoft Visual Studio, and Eclipse on same computer and works great all together.

I don't understand what could be the problem on this computer.

Load the binary in the dependency walker and show the picture. Then we can see what's wrong. I'm having all versions running on my pc. It's just a matter of environment configuration!

croussou

Sorry, by binary you mean the qtcreator.exe?

If so, it displays the IEFRAME.dll as red with a small hourglass on the side.

Is this any helpful?

Thank you.

Scylla

You want to start a application, isn't it? This application you have to load in the dependency walker.

croussou

Okay, I have loaded the .exe file of my application and this is the output...

MSVCP71D.DLL (yellow question mark)
MSVCR71D.DLL (yellow question mark)
QTCORED4.DLL (red)
IEFRAME.DLL (red + hourglass)

By the way, the application doesn't run at all. Both on Qt or from Windows.

giesbert

From Qt? You mean creator!

As you said you build for windows, which lib wants to include MSVC[P|R]71D.dll ?
QtCored4.dll is the debug version of Qt. Did you put the libs beside the exe?

Where is the screen shot of dependency viewer?

ZapB

Is this on the development machine or on some other random machine to which you are trying to deploy your application?

croussou

I am implementing and testing my application on the development machine.

This is the print screen from dependency walker with <filename>.exe loaded.

And yes, I mean Qt Creator, the damn app won't run in any way.

I have tested the application on another machine with Qt Creator and it works perfectly.

Thanks.

ZapB

Link or image is missing.

croussou

Oh I tested and it works. Open image in new tab.

Well here is the actual link

OK. Well that shows that QtCore4d.dll cannot be found in the dll search paths. LOcate this dll on your machine and make sure that it is in one of the dirs listed in the %PATH% environment variable.

Can you paste the value of the %PATH% env var please. Also where are your QT libs installed?

andre

Also, make sure you use the right QtCore4.dll file. The default SDK distribution comes with two versions: one version that is used by the Qt tools itself (build with MSVC, I think), and one that is used for the applications build with these tools, build with MingW32 by default, but overwritten if you build Qt with VS yourself. You are probably going to need the second one. That version is located in QtRoot\qt\bin, where QtRoot is the root directory of your Qt installation, for example c:\Qt\2010.05\

The version in QtRoot\bin is the version used for Qt's tools itself, and that one probably will not work.

croussou

This is the Path environment variable...

C:\Program Files\PC Connectivity Solution;C:\Program Files\ATI Stream\bin\x86;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0;C:\Program Files\ATI Technologies\ATI.ACE\Core-Static;c:\Program Files\Microsoft SQL Server\100\Tools\Binn;c:\Program Files\Microsoft SQL Server\100\DTS\Binn;C:\Qt\2010.05\mingw\bin;C:\Qt\2010.05\qt\bin;*C:\Windows\System32*

In bold is the new addition of the QtCored4.dll in the Path environment variable.

Libraries are found inside the Qt installation folder itself since I have installed the Qt SDK and not the Frameworks individually. Do you think I should install the 4.7.2 version of Qt libraries (minGW 4.4, 321 MB) instead of the already installed 4.7.0 included with the SDK?

Qt libs are installed in C:\Qt\2010.05\lib

giesbert

you must use the version you linked again or newer.
If 4.7.0 is installed on the machine and found by the path before 4.7.2 and you link against 4.7.2, it will not work!the other way round it would work

croussou

Nope, nothing. Nothing works. This is just a nightmare going on and on.

The final step is to format my computer and install everything again. It was working before so I guess it should be fine.

Any final suggestions?

croussou

Thank you all for your help.

I have formatted my computer and reinstalled everything from the beginning. Now everything works fine with Qt Creator. I have already started developing my application.

However, I can still not run the application in Windows, meaning the extension .exe, I can't really understand what is causing this. I am happy though that at least the IDE works and maybe I will deal with this problem on a later stage.

Again, thank you so much all.
