c++ - Qt 5 cannot deploy on SnowLeopard -
i have issue app doesn't run on 10.6 snow leopard.
i compile these parameters:
qmake lspro.pro -r -spec macx-clang config+=release config+=x86_64 in pro file, have these elements:
template = app headers = \ mainwindow.h \ app_mediamanager.h \ api.h \ tool_htmleditor.h \ tool_videoencoder.h \ tool_thumbnaileditor.h sources = \ main.cpp \ mainwindow.cpp \ app_mediamanager.cpp \ api.cpp \ tool_htmleditor.cpp \ tool_videoencoder.cpp \ tool_thumbnaileditor.cpp qt += network webkitwidgets widgets concurrent sql qmake_cxxflags_x86_64 += -mmacosx-version-min=10.6 qmake_macosx_deployment_target = 10.6 icon = icon.icns resources = lspro.qrc but simple hello world or example files, doesn't work...
i add libraries macdeployqt script. when running on 10.6 error in report:
dyld error message: library not loaded: /usr/lib/libc++.1.dylib referenced from: /users/username/desktop/lspro.app/contents/macos/../frameworks/qtwebkitwidgets.framework/versions/5/qtwebkitwidgets reason: image not found the question simple: how can target 10.6 clean qt5 in 10.8?
update 1:
thanks comments, looks 10.6 didn't shipped c++11 support yet, causing app crash when looking it. tried 2 solutions:
failed solution1 : rebuild qt5 noc++11 flag, resulting app starts on snowleopard fails inner elements videoplayer missing in qwebkit, unable call external binary /execute command (app crashes exc_bad_access) although binary runs fine when called directly , more undiscovered.
failed solution2 : tried naively include missing dylibs (libc++.1.dylib , libc++abi.dylib) in snowleopard, app still crashes message :

ok got work. compiled qt5 (5.1.2) on snowleopard git (have xcode 4.2 10.6 sdk) in case these config:
./configure -developer-build -opensource -nomake examples -nomake tests -qt-sql-mysql i had fix small elements in code making app crash without reason (variable names..) , ok.
just don't forget use mac deploy tool on 10.6 , app runs ok on 10.8 (untested on 10.7 assume ok.)
hope helps anyone.
the nspreferredscrollerstyledidchangenotification notification available in osx 10.7 , later, noted @ bottom of page:
qt conditionally compile os x 10.7 apis if mac_os_x_version_max_allowed >= mac_os_x_version_10_7. see e.g.:
possibly version of qt using not compiled 10.6 sdk.
there known issue: "to use qt on or 10.6, need build qt on 10.6 machine":
