Bug#974108: libkf5eventviews: FTBFS with qrand undefined

[Norbert Preining <norbert@preining.info>]

Source: libkf5eventviews
Version: 4:20.08.2-2
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

Hi

some changes in Qt seem to have triggered FTBFS here, as it fails with
/build/libkf5eventviews-20.08.2/src/prefs.cpp: In member function 'void EventViews::Prefs::createNewColor(QColor&, int)':
/build/libkf5eventviews-20.08.2/src/prefs.cpp:968:25: error: 'qrand' was not declared in this scope; did you mean 'srand'?
  968 |     QColor col = QColor(qrand() % 256, qrand() % 256, qrand() % 256);
      |                         ^~~~~
      |                         srand

qrand is defined in qglobal.h with

/*
  Reentrant versions of basic rand() functions for random number generation
*/
#if QT_DEPRECATED_SINCE(5, 15)
Q_CORE_EXPORT QT_DEPRECATED_VERSION_X_5_15("use QRandomGenerator instead") void qsrand(uint seed);
Q_CORE_EXPORT QT_DEPRECATED_VERSION_X_5_15("use QRandomGenerator instead") int qrand();
#endif

so it seems that the deprecation has actually disabled the function.

Best

Norbert
