don’t use but need to run application?

[banlinhtienphong]

I write my qt application don’t use qtwebkit, qtsql, qtxml, qtnetwork, I build successful but when create standard alone application and run then have error : unable to locate component qtsql4.dll not found. When I add qtsql4.dll then have error unable to locate component
qtxml4.dll not found,…. final, I add all 4 dll follow: qtwebkit4.dll, qtsql4.dll, qtxml4.dll, qtnetwork4.dll then application run successful.Why in my code don’t use these libraries but when run still need them?

[wysota]

Maybe you enabled all those libraries in your project file? What does it look like?

And if you uncomment these?

#SET(QT_USE_QTSQL false)
#SET(QT_USE_QTWEBKIT false)
#SET(QT_USE_QTXML false)
#SET(QT_USE_QTNETWORK false)

and comment related entries in the INSTALL section?

[banlinhtienphong]

I will receive error: unable to locate component qxml4.dll not found, for example. I also don't understand this!

[wysota]

What does your project file look like now?

[banlinhtienphong]

I forgot, I use 1 library is display with cmakelists.txt as follow:

cmake_minimum_required(VERSION 2.8)

[wysota]

Could you answer my question, please?

[banlinhtienphong]

I don't clear understand your quesion, please ask again! my project have many files...

[wysota]

I'm asking to post your cmake project file again after incorporating changes I told you to do in post #4.

The Qt3 support library, that your project specifically links, requires the Qt XML, SQL, and Network libraries. The question is, does your project really require the Qt3 support library? As far as I can tell no other library requires QtWebKit.
