Hi,
I am migrating my application from Qt4.8 to Qt 5.6 so I need to manually compile QtWebKit like documentation said:
With Qt 5.6 the following modules are no longer part of the release packages, but users can still build them from source: - Qt WebKit - Qt Declarative (Qt Quick 1)"So i did:
git clone --branch 5.6 git://code.qt.io/qt/qtwebkit.git cd qtwebkit mkdir build && cd build /home/john/Qt5.6.3/5.6.3/gcc_64/bin/qmake ../WebKit.pro makeBut I got error:
