Deploying a Qt application

[ChrisW67]

So, this is where I'm at now, please correct me if needed:
-For Linux users, I should probably compile my program using static linking (?)
Problem1: see afer.
Q1: I guess I want to compile two versions, 32 and 64 bits? How well are they going to work on different distributions?
Q2: Sould I make a deb file or something?

No, I'd use shared Qt and either ship the libraries with your binary or rely on the end-user to install Qt libraries. The deployment page explains how to launch your application form a shell script so that the libraries are found. You can wrap it in one of the common Linux deployment package or just ship a gzipped tar file that just needs to be extracted.

Most 64-bit Linux installs are capable of running a 32-bit app, so I would try that first.

-For Windows users,
Problem2: I've tried to cross-compile the app for windows from my PC using wine and mingw32, following every tuto I could find on the web, but I never got it to work; there always seemed to be an error with the qmake.conf file or something. I've come to the conclusion that even though I don't have a PC with Windows on it, I should just find one (I guess I would need one anyway to test the app) and compile my source there.
Q3: Suppose I manage to do that. Will my exe file work on all Windows computers?

Yes, XP up. If you build a 32-bit app it will run on either 32- or 64-bit systems. You can develop in a virtual machine if that is easier.

Q4: Should I try to create an installer (is it going to drive me crazy as well)?

Yes, this would normally be expected by Windows users, but you can do a zip bundle that just needs to be unzipped. The layout of a Windows deployment is covered many, many times in this forum.

-For Mac users,
Q5: I guess it's gonna be pretty much the same as for Linux case? (the advantage is, I do have a Mac at home).

You would normally build an App bundle. I cannot really help here, having never done it in anger.

Following above discussions....I tried shared library approach.
I am working on windows XP, using Qt 4.8.5, wince SDK 5.0, Visual Studio 2008.
I followed this link:
http://doc.qt.digia.com/4.7/deployment-windows.html and
configured my Qt with this command :
configure -shared -platform win32-msvc2008 -xplatform wincewm50pocket-msvc2008
Then ran command showed on prompt of Visual Studio 2008.
Everything went without error.

Then as described in above link, i tried to build 'plugandpaint' example. I built without errors but no file named 'pnp_basictools.dll' was created.
Then I used dependency walker for 'plugpaint.exe'. It shows QTGUI4.DLL, QTCORE4.DLL and COREDLL.DLL are not found. I found QTGUI4.DLL and QTCORE.DLL but not the COREDLL.DLL on my computer. I googled for this file and came to know that it is one of the wince core files similar to user32.dll.
I have wince5 sdk installed on my computer but no 'COREDLL.DLL'....how is this?
How to solve this problem?
What I am doing wrong?

I downloaded an older version.
worked fine.

Hey thanks for reply...
U mean older version of visual studio???

[harvey_slash]

I meant older version of Qt.
I use 4.8
why do you need that ?
I used this.
mingw32-make
(this was after configuring)
you need your environment variables set from the control panel.
then use (this is what I have used)
configure -platform win32-g++ -release -static -no-exceptions
||||||
(it should show lots of 'doing stuff')
then use
mingw32-make

Well thanks for your advice.
As I said I followed this link to install Qt for wince.

http://qt-project.org/doc/qt-4.8/install-wince.html

I found these links yesterday :
http://www.formortals.com/build-qt-s...-gcc-compiler/
http://www.formortals.com/how-to-statically-link-qt-4/

So I guess I have to build Qt statically. Well I am confused now. Please tell me if I am doing something wrong?
I would appreciate any advice that will point me in right direction.
