QtWebkit build failed on Ubuntu 12.04 32-bit

[Sergey Lenski]

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 build was successful 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) {

Is it possible to build WebKit on Linux 32-bit?

[Eric Seidel (no email)]

I suspect the vast majority of the people you CC'd know nothing about this issue.

Yes. It looks like in your case the automatic setup of QMAKEPATH is not working for some reason. Try compiling with QMAKEPATH explicitly set to $WEBKITDIR$/Tools/qmake.

[Sergey Lenski]

Allan thanks a lot for your reply!

I set explicitly QMAKEPATH to $WEBKITDIR$/Tools/qmake as you advised. 
The errors described above disappeared but another error occurred during compilation:

I think that is the problem. If I am not mistaken it is also the .qmake.conf file that sets the QMAKEPATH. Maybe you lost deleted it by accident?

[Sergey Lenski]

No I didn't delete anything.
I tried to build nightly build archive r143127 2013-02-17.
The problem occurs on 32-bit Ubuntu 12.04
but on 64-bit Ubuntu 12.04 the same package was build successfully.

[Sergey Lenski]

Please advise.

Those archives are created by Apple and don't contain everything needed to build the Qt port (.qmake.conf at least is missing).

Please use the official git or svn repository if you want trunk, or use the qtwebkit module bundled with Qt5 if you want the latest release.
