qt and vs

**jigfjifd** · 20th October 2010, 06:42

hello,

I'd like to add Qt 4.7 to VS2010 with the Qt add in 1.1.7.
I've already installed VS2010 and Qt and the add in.
When I make a new project, the compilation ends correctly but the executable doesn't work.
The error that is displayed by Windows is : "this application could not be launched because the configuration of this application is incorrect". Reinstalling the application could solve the problem."
I didn't make any special configuration.
What did I miss during the installation/configuration process ?

Thanks.

I think Problem is that your exe can't find the qt dlls.
Either copy them to the exe location or (better) add their location to your projects search path.

Hello,

yes you're probably right, because I didn't copy any dll or added anything to the search path.
How can I do the latter, exactly? (what to add, and where)
Besides, it seems weird to me that the error displayed by Windows is not 'missing dll' or something similar, as I've already seen this error displayed before.

thanks

"configuration of this application is incorrect" is more common to incorrect VC run time DLLs like MSVCRT.

Maybe your application is expecting VS2010 DLLs but finding VS2008 DLLs.

okay... so how do I fix this ?

Where do I find these dlls?

Are you sure you installed Qt built by VS and not the MinGW build?

**jigfjifd** · 20th October 2010, 16:21

Yes, although it's not the 2010 version. The installer is called "qt-win-opensource-4.7.0-vs2008.exe".

Run something like dependency walker and then copy the specific MS DLLs from your VS installation to the directory of the executable, or download the redistributable from MS Website.

I don't really understand, what do I have to download exactly ?
Iâ€™ve copied All the dlls (including QtGuid4.dll) of the bin folder into my executable directory, itâ€™s still not working.
The same error appears

Yes, although it's not the 2010 version. The installer is called "qt-win-opensource-4.7.0-vs2008.exe".

This could very well be the problem.
The VS2010 Dll's are probably not binary compatible with those of 2008.
You can test it by trying to run this with VS2008.
