Problems running projects
-
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.
-
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?
-
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
