cannot chdir to D:/t/qt-symbian-release/build/Source/WebKit from D:/t/qt-symbian-release/build/Source: No such file or directory, aborting. at D:/t/qt-symbian-release/build/Tools/Scripts/webkitdirs.pm line 1698
The problem is that qmake is called on Symbian from different path.
It isn't so serious now, because trunk isn't buildable because of an RVCT bug. But it would be great if we can fix it tomorrow.
I disabled clean build feature on Symbian, because it doesn't support shadow build. Because of this Source directory was removed instead of WebKitBuild.
Fix landed in http://trac.webkit.org/changeset/94667.
Making a clean build is more complex on Symbian. If Symbian folks are interested in this automatic clean build feature, ideas are welcome.
