[Rik]

Update of bug #55187 (project octave):

                Severity:              3 - Normal => 4 - Important          
                  Status:               Need Info => Confirmed

Follow-up Comment #29:

The test for qcollection generator is in m4/acinclude.m4


    AC_CHECK_TOOLS(QTCHOOSER, [qtchooser])

    OCTAVE_CHECK_QT_TOOL([moc])
    OCTAVE_CHECK_QT_TOOL([uic])
    OCTAVE_CHECK_QT_TOOL([rcc])
    OCTAVE_CHECK_QT_TOOL([lrelease])
    OCTAVE_CHECK_QT_TOOL([qcollectiongenerator])
    OCTAVE_CHECK_QT_TOOL([qhelpgenerator])


It seems like one possibility is to expand OCTAVE_CHECK_QT_TOOL macro to
accept a list of possibilities which it would check and accept the first one
found.  This is similar to how existing Autoconf macros work.

Possibility number two is to check for qhelpgenerator first, and if it is not
found, check for qcollectiongenerator.  We should not condition checks on the
version number of Qt, only on what is available in the system.

Changing the Severity to Important.  This should be fixed before the 5.0
release.
