Solved Problem opening Qt5.5.1 app on OS X 10.6.8
-
I have an application developed with Qt 5.5.1 on a system running OS X 10.10.5. The application will not open for a user attempting to use it on OS X 10.6.8. The problem report states that "App cannot be opened because of a problem." I have deployed the application bundle on my system where it works fine. Are there issues with deploying to 10.6.8 (Snow Leopard)?

Usually on that "there is a problem" screen on osx, you can get more information. Which is basically like a crash log. Can you post that info here?
Or barring that can you open the application in a debugger and show us the info from that?
And final question, did you limit your target osx platform when you built? Something like:
QMAKE_CFLAGS += -mmacosx-version-min=10.6 QMAKE_CXXFLAGS += -mmacosx-version-min=10.6Or did you use something like:
macx:QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6in your project file? ^ had to look that one up, I use cmake these days and couldn't remember the syntax.
-
10.6 support was drop, I think Qt 5.3.2 is the last version to support it.
-
10.6 was dropped as a build platform however applications should be able to run on it (provided that no API from newer version of OS X are used)

@SGaist said:
...(provided that no API from newer version of OS X are used)
That's exactly what happen, newer API are now used unconditionally and 10.6 fallback has been removed.

etcThat was for Qt5.4, so like I said, stick with Qt5.3.2 for 10.6 support.

Fair enough, then the documentation is not reflecting that move.

I went back to version Qt5.3.2 and now the app developed with it on a recent OS X runs on OS X 10.6.8. Thanks for the advice.
