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)
project(display)
find_package(Qt4 REQUIRED)
include(${QT_USE_FILE})

[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.
