Qt installation (with vs10)

jigfjifd

okay, I've made a search in my computer and it is in
C:\Qt\4.7.0\qt-everywhere-opensource-src-4.7.0
not in
C:\Qt\4.7.0
sorry. I thought it was a Microsoft windows command or something, so I didn't try to find the executable before.

So what do I need to do now exactly?
You haven't answered me regarding the path variables and the note, both of which are mentionned in the website you gave me.

I don't know for the note. If you don't have MinGW or a bash or such installed, you probably don't need to take care of it.

I never set a PATH variable when I compiled on Windows. Just start the Visual Studio Command prompt and enter:

@
cd C:\Qt\4.7.0\qt-everywhere-opensource-src-4.7.0
.\configure.exe
nmake
@

And then have a cup of coffee or better go for lunch or dinner - it takes a looooong time until everything is compiled :-)

Hello,
so I typed it and here is the result :
@
C:\Qt\4.7.0\qt-everywhere-opensource-src-4.7.0>configure.exe
Unable to detect the platform from environment. Use -platform command lineargument or set the QMAKES
PEC environment variable and run configure again
See the README file for a list of supported operating systems and compilers.
Usage: (<<followed by hundreds of lines explaining its complicated usage>>)

C:\Qt\4.7.0\qt-everywhere-opensource-src-4.7.0>@

The default options seem to have failed ("Unable to detect the platform") and the usage of this executable seems quite complicated, so maybe you can help me once more :)

@.\configure.exe -platform win32-msvc2010 @

thanks, it's working so far.

Seems like you started cmd.exe, you must start the Visual Studio Command Prompt (in VS2005/2008 it's somewhere in the Start Menu / All Programs / MS Visual Studio 200x / as far a I remember); you'll have to look around...

jigfjifd

yes you're absolutely right, I noticed a few seconds later and edited my post. Sorry for the stupid question

jigfjifd

so...
the compilation is done (finally!).
What do I have to do now to link the framework to the vs add in, and are there any files that I don't need anymore ?

goetz

The VS addin does work independently from your Qt version. Just run the installer. You then must make your self compiled Qt visible to the plugin, there is an entry in the new Qt menu of Visual Studio - just look around. Some more info on the addin can be found "here":http://doc.qt.nokia.com/vs-add-in-1.0/index.html

Just play around :-)

jigfjifd

Hello again,

Can you give me a more detailed answer please ? I've been trying to look and play around but with no result.

I don't really understand why you ask me to run the 'installer'.
I thought that "That's all. Qt is now installed.", once I have done nmake.
I don't really understand either how to build a qt application from vs, it still seems not to be working.
Finally, I didn't get which files or directories are part of the installation/compilation process and can be deleted.

Thanks.

jigfjifd

I have added the path C:\Qt\4.7.0 to the qt options in the add in.
The qt keywords are not recognized by VS.

goetz

What I meant is that you should run the installer for the Visual Studio AddIn, which is completely independent from your Qt library installations (may it be a precompiled or a self compiled one). You can even have multiple versions of the Qt libraries installed and choose which one will be used for your project.

As far as I understood from your previous posts, you should add C:\Qt\4.7.0\qt-everywhere-opensource-src-4.7.0 to the addin. It's in "Extras" menu (German version, the menu between "Debug" and "Windows"), then "Options...", then choose Qt.

Then you should follow the steps of the Getting Started guide of the "VS Addin Documentation":http://doc.qt.nokia.com/vs-add-in-1.0/index.html

I've changed C:\Qt\4.7.0\qt-everywhere-opensource-src-4.7.0 to C:\Qt\4.7.0.
I've added C:\Qt\4.7.0 to the add in (which means that in the qt options of the vc addin, in the versions tab, I have a line called : version 4.7.0, path C:\Qt\4.7.0)
It's still not working.
The first line of my program is #include <QtGui/QApplication>, but it says the file can't be found.
Yet I have a file called qapplication.h in C:\Qt\4.7.0\include\QtGui, which contains #include "../../src/gui/kernel/qapplication.h", and I have indeed a file called qapplication.h in C:\Qt\4.7.0\src\gui\kernel.

Did you set up your project using the wizard from "new project" / Qt appplication? If not you must add :\Qt\4.7.0\include to the include path of your project. The wizard adds that for you automatically, AFAIK.

jigfjifd

The project had been created with the wizard before the framework compilation which is probably why it didn't work.
I created a new project, and it works now.
Thanks a lot for your help.

I have one last question that hasn't been answered yet. Which files/directories were only part of the compilation process and can hence be deleted ?
Thanks.

goetz

For the previously created project: As far as I know you can set the Qt version to be used afterwards, that should set the appropriate include paths.

You probably can delete the .cpp files. All of the .h files are definitely needed. But I won't do that. The disk space you gain is not that much and it's not worth the effort, IMHO. If you really want you can delete the examples subdir, but I won't do that either, because it's a good source to sneak how the trolls do certain things :-)
