macdeployqt - Missing dependancies when installing.

gerry.felteau

I created an application which runs in Qt creator.
Using macdeployqt to make an installer; once installed on another Mac, I get the following error trying to execute the application :

Library not loaded: @rpath/QtWidgets.framework/Versions/5/QtWidgets

I really need to deploy this asap.

Thank you.

Hi and welcome to devnet,

What version of Qt ?
On what version of macOS ?
What parameters did you pass to macdeployqt ?

gerry.felteau

I am using Qt v5.8 on OS X 10.11.6.

I simply used :

macdeployqt mytest.app -dmg

from the release directory.

Thank you.

Might be a silly question but do you have several version of Qt installed ? If so, which version of macdeployqt are you using ?

gerry.felteau

@SGaist No, I only have v5.8 and the macdeployqt that came with it.

Thank you.

SGaist

Can you share your .pro file ?

Can you show the result of otool -L on your application ?

What does the Frameworks folder contain ?

Also, what parameters are you passing to macdeployqt ?

i had a similar problem,
in my case the deps were succesfully deployed to the qt but the application still could not find them,
(they should be in myapp.app/Contents/Frameworks)

if your issue is similar, you could try
compiling with this flag, which will create an rpath to the frameworks folder

QMAKE_LFLAGS += -Wl,-rpath,@executable_path/../Frameworks

or to fix current version without recompile you could try editing current rpath

install_name_tool -add_rpath "@executable_path/../Frameworks" myapp.app/Contents/MacOS/myapp

@chips-and-fish Thank you so much ! That fixed it.
Although I am a bit surprised as the path to Framework is an artifact of macdeployqt; one would think it would automatically add it...
