How to release a Qt Quick application?

kathy

I have built a release version of Qt Quick application using Qt Creator on Windows XP. It run great in Qt Creator. But in release folder, If I double click the exe file, a blank window pop up. I have checked the dll it used. All are in the release folder. Using Process Explorer I found comparing to run in Qt Creator, the exe does not load the image dll like: qjpeg4.dll, qico4.dll, qsvg4.dll, and qmng4.dll. But all these files are in the same directory as the exe file. Why the exe can not load these files?

they should be in imageformats directory

What you mean? I need to create a sub directory called imageformats relative to my exe file folder?

DenisKormalev

Yep and move these libs to this dir.

What I want is put evarything in release folder and release the folder to other PC which nol Qt library installed.

I have moved to the dll files but still no luck.

My directory structure is:

In release/,

myApp.exe
QtCore4.dll
QtDeclarative4.dll
QtGui4.dll
QtNetwork4.dll
QtScript4.dll
QtSvg4.dll
QtSql4.dll
QtXml4.dll
QtXmlPatterns4.dll

in release/imageformats

qgif4.dll
qico4.dll
qjpeg4.dll
qmng4.dll
qsvg4.dll

What is wrong?

all looks ok. Are you sure your problem is in not-loaded image plugins?

I copy the contents of imageformats to plugins/imageformats relative to the exe, and create a qt.conf file.

Directory structure: @
app/app.exe
app/(Qt dlls)
app/qt.conf
app/plugins/imageformats/(plugin files)
@

qt.conf @
[Paths]
Plugins=plugins
@

I tried it but no luck. I use the depends.exe to profile it and found it said can not open wintab32.dll. But I searched my PC and can not find it.
