Problems running projects
-
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
These docs are available in Qt Assistant too. [/quote]

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?
-
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).
-
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\WinSxsYou 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.
-
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?
-
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.
-
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.

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.
