Problems running applications .exe

[croussou]

Thanks for replying.

Shouldn't those .dll's have been automatically put in the Environment Variable->Path during the installation of the software? Why with Qt this insertion should be done manually?

In addition, I am running Nokia Qt SDK 1.0.2. All the applications are automatically deployed on the mobile. Is there a way to also choose to run the application as a desktop application?

What is the difference between Nokia Qt SDK 1.0 from Qt SDK for Windows? I guess the first is intended for mobile use only? How do I combine both?

I thought to install both versions but wouldn't that cause some problems?

Thanks again.

The Qt SDK 1.1 beta combine (and let you choose) different mobile and desktop Qt SDK versions.

//but still doesn't put those dll's in path
//i think it's a good thing, since you can easy "emulate" a system without Qt (a deployment target) on your development system
LE: and you can select which dll's must be included when you are creating the installer.

Alright got it.

I guess I will uninstall everything and install the Qt SDK 1.1 beta from the beginning that combines both.

So I need to add the directory paths of the missing .dll's in the Environment Variable->Path; and do that for every missing .dll?

Thanks.

No, not Path is not for individual dll, the OS will see all the dll's that are in the path you added.

So if you choose to add to Path you will need to add two paths:
1) one for the MinGW run-time dll's, it will be something like: C:\QtSDK\mingw\bin
2) another one for Qt dll's, looking somthing like: C:\QtSDK\Desktop\Qt\4.7.2\mingw\bin

Note that the Beta can install Qt built with VS (2005/2008) and those dll's won't work if you build your application with MinGW... so be careful

And, as i said earlier i recommend you to leave the Path alone and just copy the dll's (this way you will get prepared for deploying your application on other systems)

LE: be careful not to delete stuff that is already there, and note that different paths are separated by ;

What do you exactly mean by that? Copy the .dll's where?

read step 3 on this page: http://doc.qt.nokia.com/4.7/install-win.html

Also, you should be able to run your program from the <filename>-build-desktop folder by opening a Qt prompt:
Start-Programs-Qt SDK (version)-Qt Command Prompt

This prompt should have the path set correctly for finding all dll's for mingw and Qt. Unless of course if your executable depends on other 3rd party dll's, then you will have to deal with those in a similar fashion by placing them in the path or copying them to the said folder.

In general, you can only run a program from the command line if:
1) the executable is in the current folder, or
2) the executable's location is in the path

same applies to DLL's

If you want to deploy, then look at this web page: http://doc.qt.nokia.com/4.7/deployment-windows.html

Thank you all for your answers.

Everything works great now, I choose desktop app, works fine, then Sybian or Maemo still fine. I am very glad. Much appreciated.

Let's say now though, you develop an application you want for Sybian. You test it and it works like a charm and you decide to "export" it. Is this the right way to say it? Anyway, what I am trying to say is that, you want to install it on your phone or even share on a forum or with friends.

How would you do that? Is there something additional to be done?
