[Qt-interest] line number '0' for Qt libs under Qt Creator's debugger

[Garth Dahlstrom]

Hi all,

A co-worker and I are working on a project built on Qt that requires  
us to patch Qt to add Java support to QtWebkit (we will eventually  
contribute these changes back to the community btw).

As part of this effort we need to be able to debug within the Qt  
libraries effectively, currently we are stuck with an issue where by  
all Qt line numbers in the debugger's stack under Qt Creator always  
appear as '0'. (refer to the attached screenshot or http://imgbin.org/index.php?page=image&id=899 
)...  this means we are stuck injecting qDebug statements to Qt and  
relinking... which is painful to say the least.

Any tips or steps to getting line numbers for the Qt stuff under debug  
would be extremely helpful.

Here are the configurations I've tried so far - they all experience  
this behaviour of '0' for Qt line numbers shown in the image:
-- On Snow Leopard (OSX 10.6.1) --
- Qt 4.5.3 (mac ports) + Qt Creator 1.2
- Qt 4.6 Preview 1 + Qt Creator 1.3 Preview
All with and without DYLD_IMAGE_SUFFIX=_debug (the _debug frameworks  
to crash the app on start because of this Apple bug http://www.openradar.appspot.com/7309435 
  )

-- Windows XP --
Qt 4.5 + mingw + Qt Creator 1.2
Qt 4.6 Preview 1 + mingw + Qt Creator 1.3 Preview

With each of the above configurations had valid 'debug helper' built.

Please shout if you know anything I can try to fix this.

Thanks,

-G
