Building the Qt port on MeeGo 1.2 Harmattan with Qt 5 ¶

See also Building QtWebKit on Linux

This page as well as the attempt of achieving this build is work in progress. It's also our TODO list to get there.

Goal ¶

The goal is to get WebKit trunk running on the N9/N950, to a state where it can be developed sensibly.

Assumptions ¶

• Working Scratchbox setup (url??)
• Running N950/N9 with root, security disabled and scratchbox home directory mounted via NFS
• Present clones of qtbase, qtxmlpatterns, qtdeclarative and qtscript. This is the minimal set. You can add more if you'd like. (mobility'ish ones for example)
  • ​https://qt.gitorious.org/qt/qtbase
  • ​https://qt.gitorious.org/qt/qtxmlpatterns
  • ​https://qt.gitorious.org/qt/qtscript
  • ​https://qt.gitorious.org/qt/qtdeclarative

Build Instructions ¶

• Install dependencies:
  • Basic build deps, shared between Qt 5/4 and WebKit stuff: fakeroot apt-get build-dep qt4-x11 libgrob-qtwebkit
  • Dependencies needed for XCB back-end: fakeroot apt-get install libxcb1 libxcb1-dev libx11-xcb1 libx11-xcb-dev libxcb-keysyms1 libxcb-keysyms1-dev libxcb-image0 libxcb-image0-dev libxcb-shm0 libxcb-shm0-dev libxcb-icccm1 libxcb-icccm1-dev libxcb-sync0 libxcb-sync0-dev libxcb-xfixes0-dev
  • Ensure the render packages are gone: fakeroot apt-get remove --purge libxcb-render-util0 libxcb-render-util0-dev
• Apply the combined xinput2/harmattan patches to qtbase: Download wget -O patch.txt http://paste.ubuntu.com/707217/ and apply with git am -3 patch.txt
• DO NOT USE SHADOW BUILDS OF QT (MODULES) AT THE MOMENT.
• Run configure in QtBase: ./configure -nokia-developer -fast -platform unsupported/linux-host-g++ -xplatform linux-g++-maemo -force-pkg-config -nomake tests
• And build qtbase with make
• Ensure your PATH is up-to-date: cd qtbase && export PATH=$PWD/bin:$PATH
• Build QtXmlPatterns, QtDeclarative and QtScript (in that order). Simply run qmake and make in the directories of the modules.
• perl Tools/Scripts/build-webkit -2 --qt --release --no-3d-canvas

Current Issues / TODO ¶

If you find any issues that you're working on, just add them below :)

• Qt 5 TODOs:
  • Touch Input (xi2) support in Qt 5 for Harmattan (Jocelyn)
  • Input method support in Qt 5 for Harmattan
• Most obvious WebKit issues:
  • Text is funny mis-rendered in MiniBrowser -touch. (Suspect Qt 5 scaled-text-with-raster-engine bug)
  • MiniBrowser doesn't show any web content on Harmattan (Jocelyn, work in progress with solution/patch)
• Rewrite MiniBrowser in QML
• Figure out "kinetic" scrolling (pending QScroller decision)

Done ¶

• Qt 5 TODOs:
  • Build issue with the -platform/-xplatform switch and fontconfig/freetype (Simon).
  • No interaction with page possible when launching MiniBrowser with -touch. Due to broken touch mocking. (Simon)
