[webkit-help] Linking error with Qt port on Linux in Debug mode

[Osztrogonac Csaba]

Hi Benoit,

Have you got DocTypeStrings.cpp in WebKitBuild/Release/WebCore/generated/release
directory? findDoctypeEntry(...) function should be defined here. This file is
generated from doctypestring.gperf by gperf.

br,
Ossy
