Bug 388675 – >=dev-qt/qtcore-4.7: qmake does not parse correctly spaces before ! operator

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Davide Pesavento (RETIRED) 2011-10-27 16:40:31 UTC]

phonon installs a broken /usr/share/qt4/mkspecs/modules/qt_phonon.pri
When qmake reads that file, it prints the following error:

/usr/share/qt4/mkspecs/modules/qt_phonon.pri:8: Unknown test function: !contains

It seems qmake doesn't like the backslashes used to escape the newlines. Indeed if the file content is changed to:

if(!exists($$_QMAKE_CACHE_)|!contains($$list($$fromfile($$_QMAKE_CACHE_, CONFIG)), QTDIR_build)) {
    QT_CONFIG += phonon
}

(where the two conditions are both on the same line), qmake no longer throws the above error.

Oswald, would you mind having a quick look at this please?

Davide, I've added a workaround in phonon-4.5.0-r2 and phonon-4.5.1-r1. 
Could you please verify if that helps?

Anyway, seems this is a qt-core bug (thanks Oswald for identifying this!!!)

Yes, the workaround works. Thanks!
I'll keep this bug open until qmake is properly fixed though.

According to the upstream bug report, this is fixed in 5.0.0 RC 1. Do you still want to track this bug for 4.x (I don't know what the possibility of backporting is?)

Right. I don't think this will ever be fixed in qt4.
