[Qt-interest] double-click on my application bundle doesn't work

Fri Dec 4 10:57:19 CET 2009

Aha yes another mac-specific issue. This parameter is used by certain libraries to determine if the app is running in non-bundled mode (GLFW for example). Good catch.

About the mac deploy project - it becomes a big deal when you use Webkit or phonon in your app because of all the dependencies so it's worth using for that. There's nothing to stop you running an additional shell script afterwards for additional mappings (as I do for boost). I know what a time sink it is having to maintain (and debug) those scripts. The mac deploy project is a godsend and makes mac app deployment almost as painless as Windows deployment (a big thing when you consider the resistance to producing mac versions of an existing windows project).

Hi,

I finally figured what was going wrong, with the help of the Console!
My app runs in text mode if command line arguments are provided (i.e., argc > 1). And when you double click on the bundle, MacOS passes an extra argument to the binary (argc==2), hence the app was starting in text mode and complaining about the incorrect parameters.
Thank you everyone for your help,

Nicolas (definitely a nice name :) )

What about QtCore, etc ?

Anyhow, there may be other problems in your bundle, such as a missing icon, a missing plist, etc.

The Console is the place to look at, I guess ;

Best-

PS : as for the mac deploy project, it is huge, but it does not appply when having libraries other than qt in the area AFAIK... In this case, a specific script is still needed. That s why I still use my own script.

I haven't checked the console, thanks for the tip.
I think I remapped the binary correctly, here is an snippet of otool's
output for the binary:

@executable_path/../Frameworks/QtXml.framework/Versions/4/QtXml
(compatibility version 4.5.0, current version 4.5.3)
@executable_path/../Frameworks/QtGui.framework/Versions/4/QtGui
(compatibility version 4.5.0, current version 4.5.3)

I wrote my own script to do the remappings (wasn't aware of the mac
deploy project), and the app works fine if I double click the binary
instead of the bundle.
