Installing Qt 4.4 for Morons?

[chris062689]

I sware I've tried every guide I can find on how to install Qt 4.4 OpenSource.
I just simply can't figure out how to properly install it!

Does anyone have a "tried and true" method for installing Qt 4.4 (+ Eclipse / Visual Studio 2003, whichever's fine.) on Windows XP SP3? Could you walk me through it please? :crying:

I've been looking at Qt, and it seems like a really powerful framework, I just can't get it to install... :rolleyes:

I'm going to try this guide...

The easiest thing to do is to download the version for MinGW that has an installer and run it. Afterwards you are immediately ready to go. If you want to integrate your installation with some IDE, install the Eclipse integration. Note that this is optional, the framework will work without Eclipse - you can even use notepad to develop your applications.

Well, following that guide I'm stuck at the configure part.

After looking around, it appears that Microsoft Visual Studio C++ Express isn't supported? :crying:

Is MSVS 2005 Express supported?
Is there a way I can use MSVS 2008 Express with Qt?

I'll just do it with MSVS 2005 Express...
I followed this guide: http://53prime.com/?p=87
I'll report back if it works!
[EDIT: Nope, msvs 2005 express isn't supported either?!]

[chris062689]

Does anyone have a good tutorial on how to install Eclipse, Qt, Mingw?
I guess I'll just use Eclipse. I really don't care as long as I can use Qt! :p

[wysota]

As far as I know msvc-2008 is supported... I can see support for it in both the commercial and open source editions. If you use prefix in Windows, you have to manually copy the mkspecs directory or issue make install_mkspecs before building Qt. There is something wrong with the compilation process and qmake looks for the specs in a wrong directory.

[chris062689]

Trying Eclipse... this is giving me a migraine.

(After I ran configure, I ran mingw32make, this is what happened)

[tons of code here]

I think I'm getting closer, but what's wrong?

[wysota]

Ok, but why are you trying to build Qt if you already have it built for MinGW? Don't try to make things harder than they are.

[chris062689]

When I try to compile a program using g++, it comes back with errors...
So I assumed I needed to compile it..

OK, what steps do you suggest doing to install Qt / Eclipse? :(

[wysota]

I already wrote that few posts earlier. Install the binary package and you're ready to go. If you want eclipse integration, install the integration package and again you should be ready to go. Just make sure proper environment variables are defined. You can do that by using the "Qt command prompt" entry from the start menu.

[chris062689]

What?
I tried installing that binary package, and then tried compiling my Hello World program with "g++", it came back with errors

C:\Documents and Settings\Administrator\My Documents\QtExamples\helloworld>g++ h

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QPushButton hello("Hello world!");
hello.resize(100, 30);

hello.show();
return app.exec();
}

I'm so confused what I'm SUPPOSED to do and what I'm NOT SUPPOSED to do.. :crying:

[chris062689]

/sheds a tear. :crying:
I *finally* compiled my own program! :)

But.. it took so many steps...

Is there anyway I can.. condense that?
How exactly do I integrate it with Eclipse now?

Wait.. why does it only work when I execute it from the QT command line?
Why can't I run it in Windows Explorer? :confused:

This application has failed to start because mingw10.dll was not found.

[wysota]

Congatulations. Reading the docs often pays back :)


Is there anyway I can.. condense that?
You rarely need to call qmake again, so when you change something and want to recompile, you only call make.


How exactly do I integrate it with Eclipse now?
You might start with downloading the Qt Eclipse integration available from Trolltech site.

I think you already know the answer :)

You sir, do not know how to read the Topic Title.
Re: Installing Qt 4.4 for Morons?

Why can't I run them without the Qt Command Prompt?

[wysota]

It would help if you actually started reading some docs instead of trying things blind...

The command prompt sets paths and environment variables to both Qt and MinGW. Without it you need to make sure your system can find all the libraries when running an application. In that case the runtime of MinGW that is probably not sitting where it should (in a global system library path like C:\Windows\System or a local library path like the directory containing the binary you are trying to execute). This is all basic stuff concerning programming. You should really try to learn your deployment environment (Windows operating system in your case) before doing any software development on your own.
