Here's the latest scoop.
I can build tqtinterface and arts without a hitch. Building kdelibs fails. Therefore I haven't yet tested building kdebase.
As of svn 1170747 I could build kdelibs.
The first error message I received:
kservicegroup.cpp:76: error: 'QDir' has not been declared
I guessed and added the following to kservicegroup.cpp:
That stopped that error message . :) So kservicegroup.cpp needs to be patched.
The next set of error messages I encountered:
kurlbar.cpp:611: error: 'KIO' has not been declared
kurlbar.cpp:611: error: expected `;' before 'uds'
kurlbar.cpp:613: error: 'KIO' has not been declared
kurlbar.cpp:613: error: 'uds' was not declared in this scope
I'm attaching a log of the failed kdelibs build.
