I managed to compile Qt everywhere 4.8.1 libraries and examples with QtWebKit for Windows CE :
configure -platform win32-msvc2005 -xplatform wince60standard-x86-msvc2005 -webkit

The problem is when I try to run any example on Windows CE, the application crashes : Application fancybrowser.exe encountered a serious error and must shut down
On the platform builder, I can see "First-chance exception is an unknown module (0xC0000005 : Access Violation)" and on the output "DoImport Failed! Unable to import from Library 'QtWebKit4.dll'".

Does anyone have an idea of what the problem could be ?
