How to command line build a proper dmg from a Qt app

SGaist

Just use a recent version of macdeployqt. The option is -fs.

Looks like -fs did somthing with filestystem. I can see it logged the follwing extra thing. But its still the same issue

Log: Image will use "HFS+"

But, If I open MyApp/MyApp.app/Contents/MacOS/MyApp then it complains the following on console and gives up with a crash

QQmlApplicationEngine failed to load component

You did not use the qmldir option when running macdeployqt.

Ah superb ! This made a difference. Now if I doubled clicked on the dmg and opened MyApp/MyApp.app/Contents/MacOS/MyApp that is inside it. It works and I am able to launch my app.

Thanks a lot till here.

But I am still curious why just double clicking on MyApp dies not work? Why do I have to run MyApp/MyApp.app/Contents/MacOS/MyApp instead of just MyApp ?

SGaist

Do you have any error message ?

Nelson_Piquet

@SGaist
The error message says following with a pop up

You can’t open the application “MyApp.app” because it is not
supported on this type of Mac.

SGaist

Are you using a pre-built version of Qt to build your application ?

By the way, why not use a more recent version of 5.9 ?

Nelson_Piquet

@SGaist

Do you mean 5.9.6 ? I am using 5.9.4 but this error occurs even if I build with 5.11.2.

SGaist

Can you show your .pro file ?

Nelson_Piquet

@SGaist

My .pro file has so many things which is due to multiple stuff and it would not make much sense to share it here. But I have set QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.12 and QML_IMPORT_PATH is set to nothing. Plus, following are some more settings I have in my .pro which might be relevant to this question

CONFIG += c++14
CONFIG -= bitcode

I am marking this Topic as solved. Do let me know if have a suggestion on this last error.
