[Qt4-preview-feedback] Qt 4.5/Cocoa crash with -static -no-framework, even if qt_menu.nib in app bundle

[Martin Dyde]

Hello Trenton & co,

Background: some time last year, after you released the original 
Qt/Cocoa alpha, I spoke to you about using -static -no-framework for Qt 
Cocoa builds, since we'd prefer to build it that way (we don't need 
plug-ins, it simplifies maintenance for our installer (which is 
necessarily quite complex), and, our app does seem to start slightly 
faster when Qt is linked statically).  I must confess to knowing very 
little about Objective-C/Cocoa programming, so please forgive me if this 
question is just a result of ignorance on my part.  (The new macdeployqt 
util does indeed make the build process enormously easier when using 
private frameworks -- many thanks for that -- and we'll go for that 
approach if we do have to.)

./configure -help says:

"-cocoa ............. Build the Cocoa version of Qt. Note that 
-no-framework and -static is not supported with -cocoa. Specifying this 
option creates Qt binaries that requires Mac OS X 10.5 or higher."

... i.e. that -static and -no-framework aren't officially supported for 
Cocoa.

However, you mentioned to me that building with -static and 
-no-framework should still work if the $QTDIR/src/gui/mac/qt_menu.nib 
bundle (including its contents) was copied as <APP 
DIR>/Resources/qt_menu.nib.

That did indeed work fine with the original alpha releases of Qt/Cocoa 
last year, but it no longer seems to work with the recent Qt 4.5/Cocoa 
snapshots, e.g. qt-all-commercial-src-4.5.0-snapshot-20090212.tar.gz.

If I try building Qt with:

./configure -prefix $PWD -platform macx-g++ -static -debug-and-release 
-no-framework -sdk /Developer/SDKs/MacOSX10.5.sdk -arch x86_64

... Qt builds successfully.  However, if I then copy 
$QTDIR/src/gui/mac/qt_menu.nib into 
$QTDIR/examples/mainwindows/application/application.app/Resources and 
then try to run it, I get the following crash:

--------------------------------------

Is that something that can easily be fixed/worked around on either my 
part or your part?  Or do we definitely have to go for the frameworks 
approach now for Cocoa?
