[Octave-bug-tracker] [bug #50129] Incorrect Qt version chosen after automatic updates to configure

[John W. Eaton]

Follow-up Comment #8, bug #50129 (project octave):

Mike, are you using "configure -C" to enable config.cache?  I do see the
problem if I use the cache:


rm -f config.cache
configure -C   ## MOCFLAGS is set to -qt5 in Makefile
touch configure
make V=1 Makefile  ## ultimately runs "./config.status --recheck" and MOCFLAGS
is empty in Makefile


note that


rm -f config.cache
configure -C   ## MOCFLAGS is set to -qt5 in Makefile
touch Makefile.in
make V=1 Makefile  ## ultimately runs "./config.status Makefile" and MOCFLAGS
is empty in Makefile


It's the "--recheck" part (with the cache) that causes the trouble.  This
happens because of the problem that I noted in comment #6 about using MOC as
the cache variable.
