Deployment of Qt App on Mac - dmg file does not run on a different machine

Clovea

Hi All,

I am very new to Qt/QML. I have installed Qt 5.3.1 on my mac and wanted to package my application. Following the instructions given "here":http://qt-project.org/doc/qt-4.8/deployment-mac.html#the-mac-deployment-tool, I successfully created a disk image file (.dmg) with my application. I can open/install and run it on my machine and everything works fine. When we try to run the same file on a different machine and we are getting the following error.

I have used "macdeployqt" and "otool -L" commands but it still does not solve my problem.

Can someone help me sort out this problem?

Thank you,

Clovea.

Hi, when you run "macdeployqt" did you specify the -qmldir switch? "Example here":http://stackoverflow.com/a/20903329/233402

Also, could you post a "otool -L" on your freefalltower.app/Contents/MacOS/freefalltower app?

Hi,

I have tried to add the qmldir flag in my "macdeployqt" command, it still does not work. Here is the output of my otool -L

Hmm the otool -L looks good, could you also open your .dmg file and do a "otool -L" on your app inside it, i.e. do a "cd /Volumes/VOLUME/..." etc.?

The output of the otool -L command is this:

Hi,

Are you using any custom library ?

hskoglund

Yes, also you could try with making an empty Widgets app, do macdeployqt and make a .dmg of the Widgets app, and see if that .dmg unpacks and runs ok on your other machine.

The following works for me for a simple Qt app-

go to build dir of your APPNAME, which is called build-APPNAME-Desktop_Qt_5_3_clang_64bit-Debug

~/Qt/5.3/clang_64/bin/macdeployqt APPNAME.app -dmg -qmldir=/Users/USERNAME/Qt/5.3/clang_64/qml -verbose=3

this generated a APPNAME.dmg file which I was able to use on another MacBook.

Thank you Shantanu, your solution does work for me as well.
