You can use the dependency walker depends.exe. It is not provided by Microsoft anymore, but you can download it from its own homepage [dependencywalker.com].

PS:
For some hints on the usage of depends.exe, see this older thread [developer.qt.nokia.com]

Did you compile Qt from scratch (so from the zip file) or are you using a precompiled version?
The pre compiled version is AFAIK not compiled for MSVS 2010.

Thank you for answer. I Tried Dependency Walker, is seems like useful program, but it don’t help. I really didn’t have some dlls files, but when download these it doesn’t help. So error is somewhere else. Down is event log (Something is in Czech, but I thing it isn’t important.).

I do use precompiled version for VS 2008. Are you sure this is the reason for the error? I’ve read somewhere that version for VS 2008 is ok for 2010. I’ve wanted to avoid compile my own version because I’m beginner with VS and also with programming in general. But I probably found some tip how to do it and try to compile it.

You must not use the VS2008 Qt binaries together with VS2010. Absolutely never.

As there are nor prebuilt binaries for VS 2010, you will have to build Qt manually:

• Get the sources from the Qt download page [qt.nokia.com], do not use the sources included in the binary download for VS 2008!
• extract the zip
• call configure.exe
• run nmake
• point your project to use the newly created Qt

Thank you, although maybe little late, for advice I finally compiled Qt. According this: http://doc.qt.nokia.com/4.7/install-win.html
It took me (on my laptop) more than 3 hours but it finally working.

Hi,

I’m also trying to get QT to work with MS Visual studio 2010 professional.

I followed the link: http://doc.qt.nokia.com/4.7/install-win.html

I was able to compile and nmake the QT. When I launch the MS visual studio IDE, and tried to use QT I get the following error, it seems it cannot recognize QT. I added QT/bin to my environment variable path.

So I don’t know the problem?

compiling error:

fatal error C1083: Cannot open include file: ‘QPoint’: No such file or directory

fatal error C1083: Cannot open include file: ‘QMainWindow’: No such file or directory

fatal error C1083: Cannot open include file: ‘QString’: No such file or directory

Did you install the vsaddin [qt.nokia.com] ?
You should try to setup a new Qt project.

I have been doing it ever since VS2010 was released and never come across any problems. Is it really that bad?

Yes, it is. You will most likely run into troubles with memory management and other strange errors. From what I’ve heard, it could be possible to mix code compiled by two VS versions, but you really must know the internals of VS etc. to be aware of the implications. It’s usually not worth the effort unless you cry for strange errors :)

For Qt 4.8 there is a VS 2010 pre-compiled binary it seems (haven’t tried it yet), for 4.7 only VS 2008 is available http://qt.nokia.com/downloads/downloads#qt-lib
