Which DLL files to need to run exe files in other computer?

dbzhang800

You need re-read the documentation “Creating the Application Package” .

The windows platform plugin must be deployed, it's required by all the GUI application.
Seems that Qt5Sql.dll is deployed by yourself. so it nearly sure that database plugins is needed by your application.
other plugins such as imageformats is required if you used .gif/.jpg/... files in your application.
...

Please use a process tool such as Microsoft's process explorer to monitor your application, so you can easily find out all the dlls needed by your application.

Will I must copy these dll - I comment above - (in C:\Qt\Qt5.1.0\5.1.0\mingw48_32\bin) to RELEASE folder?

I cant' copy them to another folder such as \MyProject\Myresources\Mylib folder?

When I copy to target machine. It show

This application has requested the Runtime to terminate it in an unusual way Please contact the application's support team for more information

May you explain it for me. I'm looking forward to receiving your msg.
Thanks,

Thanks,[/quote]That means your program crashed. Does it run properly on your development PC?

Did you remember to include platforms\qwindows.dll?

What OS does your development PC use? What OS does your target PC use?

All programs will look for DLLs in the same folder as the .exe -- that is normal. If you look inside C:\Program Files, you can see that most programs put the .dll files together with the .exe files.

If you want to be tidy and clear, put a Shortcut on your desktop.

1.It's run fine when I run it on my development PC.

2.I forgot include platforms\qwindows.dll.

3.I use win7-32bit at development PC and target PC use win7-32bit too.

I have been checking how to add platforms\qwindows.dll to my project.

Will I copy it to \release\platforms\qwindows.dll and run executable file.

It didn't work in here. Will I reconfigure something at .pro file?

1.It's run fine when I run it on my development PC.[/quote][/quote]Sorry, I wasn't clear before: Does it run properly on your development PC, outside Qt Creator? Close Qt Creator, and run your program by launching the .exe file directly.

[quote]3.I use win7-32bit at development PC and target PC use win7-32bit too.[/quote]Ok, that should be easier then. (Deployment is harder if you build on Windows 7 and transfer to Windows XP)

[quote]I have been checking how to add platforms\qwindows.dll to my project.

Will I copy it to \release\platforms\qwindows.dll and run executable file. [/quote]Yes, that is correct. Your folder should look like this:

\release\application.exe
\release\Qt5Core.dll
\release\Qt5Gui.dll
\release\Qt5Sql.dll
\release\Qt5Widgets.dll
\release\icudt51.dll
\release\icuin51.dll
\release\icuuc51.dll
\release\libgcc_s_dw2-1.dll
\release\libstdc++-6.dll
\release\libwinpthread-1.dll
\release\platforms\qwindows.dll

(but maybe it needs more. Did you use "Process Explorer":http://technet.microsoft.com/en-au/sysinternals/bb896653.aspx, as suggested by 1+1=2?)

[/quote]No, the .pro file is only for compiling and linking.

When I copy a basic project to target PC. It work fine.

Yes,I close the Qt Creator and It run fine at development machine.

It's seem missing some dll when I ran real project at target machine.I use sqlite for database and some images for icon. That's all.

It show
C:\Qt\Qt5.1.0\5.1.0\mingw48_32\plugins\imageformats\qgif.dl at Process Explorer.
Will we create release\imageformats folder?

SGaist

Hi,

The deployment documentation "plugins chapter":https://qt-project.org/doc/qt-5.0/qtdoc/deployment-windows.html#qt-plugins

explains that.
Basically you need to create the plugins folder and the needed subfolder like imageformats.

appfolder
appfolder\plugins
appfolder\plugins\imageformats
etc...

I've written a doc note with some examples about it but it has been on moderation for some time now and I can't access it.

yes, thanks for your solution . But it didnt' work , Will we NEED reconfigure something at .pro file?

After I add these folder.

*appfolder\plugins*
appfolder\plugins\accessible
appfolder\plugins\imageformats
appfolder\plugins\platforms
appfolder\plugins\sqldrivers

It didn't work. So that, I try with :

*appfolder\release\plugins*
appfolder\plugins\plugins\accessible
appfolder\plugins\plugins\mageformats
appfolder\plugins\plugins\platforms
appfolder\plugins\plugins\sqldrivers

It didn't work too.

remove the plugins from your paths please

The only exception is platform, it should be in appfolder directly so:

appfolder\plaftorms
appfolder\plugins\imageformats
etc..

@SGaist : Do you mean that we* will not* put platforms and plugins to RELEASE folder. Will We put these folder to appfolder?

Both
@
appfolder\plugins\imageformats
@
and
@
appfolder\imageformats
@

can be used.

But if we use the former, a configure file called qt.conf is needed. while the latter doesn't need this file.

It's still didn't work. May you access my machine by teamviewer?.

I replace all of them by :

@appfolder
appfolder\accessible
appfolder\imageformats
appfolder\sqldrivers@

@appfolder\release\plugins
appfolder\release\plugins\accessible
appfolder\release\plugins\mageformats
appfolder\release\plugins\platforms
appfolder\release\plugins\sqldrivers@

But it didnt' work.

? Offline

I put

@appfolder\plugins
appfolder\plugins\accessible
appfolder\plugins\mageformats
appfolder\plugins\platforms
appfolder\plugins\sqldrivers@

And write code:

@int main(int argc, char *argv[])
{
qApp->addLibraryPath("../plugins");
QApplication a(argc, argv);

MainWindow w;
w.show();

return a.exec&#40;&#41;;

}@ at main.cpp

But it didnt' work. Just show "Microsoft Visual C++ runtime library".

I make some basic project for testing. It work fine if we use images , but if when I use sqlite for connect. It shows error “Microsoft Visual C++ runtime library”. I think that because we didn't reconfig plugins. So that, It shows error.
