Build Qt 4.7.4, on OSX Lion Machine, with MacOS10.5 SDK - 32 bit target

ronM71

@./configure -platform macx-llvm -arch i386 -sdk /developer/SDKs/MacOSX10.5.sdk@

It succeeds

@make@

Builds for a while and then errors:

Am I trying the formally impossible? Or perhaps I should use a different compiler?

Check that /Developer/SDKs actually exists. With the latest Xcode 4.3 update, the SDKs are now under /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs on my machine.

me too,have the same problem,seeking for solution.I'm developing on Mac os x 10.7.3,and would compile a program running on 10.5 and later. trying to compile QT 4.7.4 or 4.8.0. using:./configure -prefix /Users/mac/QTSDK_474_X86_10.5 -platform macx-g++ -sdk /Developer/SDKs/MacOSX10.5.sdk -arch x86 -release -opensource -nomake demos -nomake examples -no-qt3support -no-multimedia -no-opengl -no-openvg -no-libjpeg -no-libtif.

get the same build result error

 I've find another way to fit the requirement,using the "MacOSX10.6.sdk" instead of "MacOSX10.5.sdk",compile the QT 4.7.4,then use it to complie my application. my application can work on 10.5.
That's my solutions.

I have documented some of the issues here:
