I'm running Mac OS X 10.6 on my development machine and am building a QT application that I would like to work on 10.5 (and 10.4) as well as 10.6. My application has both a library component and a gui component, each as their own QT project with dependencies.
I have followed the instructions of the QT deployment guide. In both .pro files I have added:
CONFIG += x86 ppc
QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.4
I peered inside the makefile, and confirmed that it includes a line:
export MACOSX_DEPLOYMENT_TARGET = 10.4
I built QT static with the following configure:
./configure -universal -sdk /Developer/SDKs/MacOSX10.5.sdk/ -opensource -static -debug-and-release
I compiled my application in QT Creator, and the resultant application runs flawlessly on 10.6 machines, but crashes on 10.5 machines.
Is there anything else I need to be doing to get a QT application working on OS X 10.5? Does anyone have any idea why this is crashing?
It's crashing with this message:
