[Solved] QT5 QtWebkit build failed on Ubuntu 12.04 32-bit (WebKit nightly build)

[SergeyLenski2392]

Hello, everyone!

I couldn't build the last Webkit + QT5 on Ubuntu 12.04 32-bit.

I tried to build QtWebKit accroding to: http://trac.webkit.org/wiki/BuildingQtOnLinux .

On Ubuntu 12.04 64-bit all is OK but on 32-bit build failed.

QT

QT5 was build successfully with https://github.com/ossy-szeged/qt5-tools/blob/master/build-qt5.sh
The result was the same when I tried to build WebKit with http://releases.qt-project.org/qt5/5.0.1/qt-linux-opensource-5.0.1-x86-offline.run

WEBKIT

http://nightly.webkit.org/
Nightly build: WebKit-r141714

ENVIRONMENT

The environment variables seem to be correct:
QTDIR and PATH were set according to the instruction

• QTDIR=/home/zaq/work/qt5-tools/qt5/qtbase
• PATH=$QTDIR/bin:$PATH

QMAKE

qmake -v
QMake version 3.0
Using Qt version 5.0.0 in /home/zaq/work/qt5-tools/qt5/qtbase/lib

I suppose the first problem is that qmake cannot process pro-files commands like
@
use?(3D_GRAPHICS) {
@

I would be grateful for any help.

Why not use standard instructions from "Qt Project":http://qt-project.org/wiki/Building_Qt_5_from_Git?

Have you got all dependencies (Perl, Python, Ruby)?

[SergeyLenski2392]

I need the latest version WebKitQt port on Linux.

Build instructions: http://trac.webkit.org/wiki/BuildingQtOnLinux .
All dependencies are installed according to http://trac.webkit.org/wiki/BuildingQtOnLinux#DependenciesforspecificLinuxdistributions

I use the same instructions to build Ubuntu 12.04 64 - bit version and there is no any problem with build.

This error occurs on Ubuntu 12.04 32 -bit

[SergeyLenski2392]

The problem is that WebKit nightly builds http://nightly.webkit.org/
don't contain everything needed to build the Qt port
(.qmake.conf at least is missing).

On 64-bit Ubuntu I've got the sources from git repository.
but on 32-bit Ubuntu it was a 'Nightly Build' archive file :)

So to build the latest WebKit Qt port it is need the official git or svn repository.
