Problems running projects


  • Hi there,

    I am having problems running my applications and i get constantly the error "<file name> exited with code -1073741515". I cannot even run the samples included in the platform.

    I have tried to search and google a bit around but no luck. Even tried to reinstall, nothing works. Any ideas?

    Thank you in advance.

  • a quess you work on a linux distro?
    try install g++

  • Ah no, in truth I am on Windows 7. Hope this helps.

    I am very frustrated with this.

    Thanks

  • Hi,

    which tool chain do you use for building the windows app?
    Do you build debug or release?
    Which Qt / SDK version?

    All this would help identifiing your problem.

    EDIT

    if you convert your decimal number to hex, it is C0000135
    C0000135 means dll not found.

    You could use dependency viewer to check, which dlls are not found.

    Additionally, look at the post of Volker in another Thread, he points some links:

    These docs are available in Qt Assistant too. [/quote]

  • Hi there,

    Thanks for replying.

    To start with I am using Qt Creator 2.0.1 based on Qt 4.7.0(32bit).

    When I try to debug I get this Error: Executable Failed - During startup program exited with code 0xc0000135, just like as you pointed out and then when I try to run the program I get the error described above.

    Then I used Dependency Walker to check the missing dlls related with qtcreator.exe

    SHLWAPI.DLL and IEFRAME.DLL are displayed highlighted where on the bottom a message says "Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module." I don't know how this will help but next to IEFRAME.DLL, there is a small hourglass.

    That's all.

    Thank you all in advance. I hope this will be solved fairly soon because I have a project I need to work with.

  • Do you see any messages in the detailed debug log of qt-creator about which dll it cannot find?

    Can you launch you app from the command line (or windows explorer)?

    0

  • Alright, to start with, no messages found in the detailed debug log.

    However, I have tried to launch the application from the command line and i get the following message "The program can't start because mingwm10.dll is missing from your computer. Try reinstalling the program to fin this problem."

    Hope this helps.

    Thank you.

  • Either place that dll in the same dir as the executable or make sure that it can be found by the system by placing the dll's parent dir in the %PATH% search path. Note that you will need to restart qt-creator after modifying the environment variables for qt-creator to be aware of them.

  • Hi croussou,

    perhaps the links from volkers post help you to find, what you need:

    [quote author="Volker" date="1300382119"]See the general hints on "Deploying Qt Applications":http://doc.qt.nokia.com/stable/deployment.html and the specific instructions for "Windows":http://doc.qt.nokia.com/stable/deployment-windows.html

  • Okay, I located the .dll in question in the following directories.

    C:\Qt\2010.05\qt\bin\mingwm10.dll

    C:\Qt\2010.05\mingw\bin\mingwm10.dll

    Question is, why windows search cannot locate the .dll and I need to manually locate them in their directory?

    Now, as far as ZapB's post is concerned, how do I put the dll’s parent dir in the PATH search path?

    0

  • It depends on how your %PATH% environment variable is configured. If the dir:

    C:\Qt\2010.05\qt\bin\

    is listed in that env var then windows will look in there for dll's when it loads applications. To set the env var (from memory) go to Control Panel->System->Advanced->Environment Variables. Then edit the %PATH% entry to include the above path (don't forget to separate it from the other paths with a semi-colon).

    I've not used the Qt SDK on Windows but I am surprised that it did not set this up as part of the installation.

    Then restart qt-creator and see if you can debug your app. You shoudl also be able to run it from Windows explorer too now (assuming no other dll's remian unfound).

    0

  • windows searches for dll in the following way:

    Current directory of your executable

    windows system directory

    all paths loacted in the %PATH% environment variable

    Side by Side is searched in :
    C:<Windows>\system32\WinSxs

    You can look into this "MSDN article":http://msdn.microsoft.com/en-us/library/ms684175(VS.85).aspx for more information on that.

    bq. The first directory searched is the directory containing the image file used to create the calling process (for more information, see the CreateProcess function). Doing this allows private dynamic-link library (DLL) files associated with a process to be found without adding the process's installed directory to the PATH environment variable. If a relative path is specified, the entire relative path is appended to every token in the DLL search path list. To load a module from a relative path without searching any other path, use GetFullPathName to get a nonrelative path and call LoadLibrary with the nonrelative path. For more information on the DLL search order, see Dynamic-Link Library Search Order.

  • Sigh...

    I am afraid it didn't work. I am desperate right now so much, I really need to get some work done during the weekend.

    Any other possible solutions? I don't know maybe I did that process in the wrong way? I have created a new variable called qtcreator and inserted C:\Qt\2010.05\mingw\bin;C:\Qt\2010.05\qt\bin.

    Do you think I did something wrong?

    I am sorry this thread is taking ages to solve.

    0

  • What? Who said anything about making a new environment variable called qtcreator? Just add C:\Qt\2010.05\mingw\bin;C:\Qt\2010.05\qt\bin\ to the existing PATH environment variable.

    0

  • Okay, this time it was done right.

    Still doesn't work though, still displaying same message in Qt, but in windows the .exe file displays a new error now.

    "The program can’t start because MSVCP71D.dll is missing from your computer. Try reinstalling the program to fix this problem.”

    What does it mean anyway? At least has the other one been solved?

    0

  • 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.
    "Dependency Walker":http://www.dependencywalker.com/

    0

  • 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!

    0

  • 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.

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

    0

  • 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.

    0

  • 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?

    0

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

    0

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

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

    !http://img854.imageshack.us/i/dependencywalker.jpg/(DependencyWalkerPrint)!

    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.

  • Link or image is missing.

    0

  • 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?

    0

  • 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.

  • 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

    0

  • 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

    0

  • 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?

    0

  • 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.
