            Bug ID: 359658
           Summary: Compilation of preprocesstask.cpp fails if
                    QT_NO_CAST_FROM_ASCII is defined
           Product: digikam
           Version: 5.0.0
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Panorama
          Assignee: digikam-devel at kde.org
          Reporter: thisco at webcake.de

Found this problem today while trying to compile the digikam-9999 ebuild (git
master) on my Gentoo system. Apparently, QT_NO_CAST_FROM_ASCII is defined on my
side, causing the QString(const * char) c'tor to be private. As a consequence I
was not able to compile preprocesstask.cpp without modifying it, such that
QImg::save(const QString&, FORMAT, DImgLoaderObserver* const) gets called in
PreProcessTask::computePreview(const QUrl& inUrl) instead. The patch is
included in the "Additional Information" section.

Reproducible: Always
